KRAVITCH, Circuit Judge:

William Thompson, a prisoner of Florida, filed a petition for a writ of habeas corpus in the federal district court asking that his murder conviction and death sentence be set aside. After an evidentiary hearing the district court denied relief. We affirm.

BACKGROUND

The Florida Supreme Court summarized the facts of the crime in deciding Thompson's direct appeal:

The appellant Thompson, Rocco Surace, Barbara Savage, and the victim Sally Ivester were staying in a motel room. The girls were instructed to contact their homes to obtain money. The victim received only $25 after telling the others that she thought she could get $200 or $300. Both men became furious. Surace ordered the victim into the bedroom, where he took off his chain belt and began hitting her in the face. Surace then forced her to undress, after which the appellant Thompson began to strike her with the chain. Both men continued to beat and torture the victim. They rammed a chair leg into the victim's vagina, tearing the inner wall and causing internal bleeding. They repeated the process with a night stick. The victim was tortured with lit cigarettes and lighters, and was forced to eat her sanitary napkin and lick spilled beer off the floor. This was followed by further severe beatings with the chain, club, and chair leg. The beatings were interrupted only when the victim was taken to a phone booth, where she was instructed to call her mother and request additional funds. After the call, the men resumed battering the victim in the motel room. The victim died as a result of internal bleeding and multiple injuries. The murder had been witnessed by Barbara Savage, who apparently feared equivalent treatment had she tried to leave the motel room.

Thompson v. State, 389 So.2d 197, 198 (1980).

Thompson and Surace both pled guilty and were sentenced to death, but these pleas and sentences were set aside by the Florida Supreme Court. Thompson v. State, 351 So.2d 701 (1977); Surace v. State, 351 So.2d 702 (1977). Upon remand, Thompson again pled guilty, and again was sentenced to death. The Florida Supreme Court affirmed, 389 So.2d 197 (1980); the state courts also denied collateral relief. 410 So.2d 500 (1982). Thompson then filed a petition for habeas relief in the federal district court raising numerous grounds. He subsequently sought to amend his petition to add claims based on ineffective assistance of counsel. Because these additional claims had not been presented to the Florida courts, the district court granted a continuance to allow Thompson to exhaust the claims in state court and the state appealed. This court affirmed the district court's continuance, but also stated that the district court, in its discretion, could have accepted the state's offer to waive exhaustion with respect to the new claims. Thompson v. Wainwright, 714 F.2d 1495 (11th Cir. 1983), cert. denied, 466 U.S. 962, 104 S.Ct. 2180, 80 L.Ed.2d 562 (1984). On remand, the district court accepted the waiver, and, after an evidentiary hearing, found all of Thompson's claims without merit.

I. INEFFECTIVE ASSISTANCE CLAIMS

Thompson contends that his counsel, Harold Solomon, was ineffective during entry of his second guilty plea and the sentencing proceeding. Solomon's representation of Thompson began after the first plea was set aside and continued through the state proceedings for collateral relief.

In Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984), the Supreme Court articulated the standards for reviewing claims of ineffective assistance of counsel. The petitioner can prevail only if counsel's "acts or omissions were outside the wide range of professionally competent assistance," id., 104 S.Ct. at 2066, and "there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different." Id. at 2068. The questions of whether counsel's performance was deficient, and whether the defendant was prejudiced by any deficiency are mixed questions of fact and law. 104 S.Ct. at 2070. The district court ruled that Solomon was not ineffective, and found that numerous of the alleged errors by Solomon resulted from Thompson's own actions.

A. Entry of the Guilty Plea

In Hill v. Lockhart, ___ U.S. ___, 106 S.Ct. 366, 370, 88 L.Ed.2d 203 (1985), the Court made clear that the Strickland standards apply to the assistance of counsel in entering a plea. The record here indicates that after the Florida Supreme Court vacated Thompson's first guilty plea, Thompson again decided to plead guilty, although Solomon discussed the ramifications of the plea with Thompson and told him that he was prepared to try the case. Nevertheless, Thompson contends that Solomon's assistance before and during the plea proceeding fell outside the wide range of professionally competent assistance, and that but for Solomon's ineffective assistance there is a reasonable probability that Thompson would have been found incompetent to enter a plea.

In Strickland, the Court noted that "[i]f it is easier to dispose of an ineffectiveness claim on the ground of lack of sufficient prejudice, which we expect will often be so, that course should be followed." 104 S.Ct. at 2070. With respect to the plea proceeding, petitioner's ineffectiveness claim falls into this category. Thompson contends that Solomon was aware that Thompson had mental difficulties, and yet allowed the plea proceeding to go forward. Although the record does indicate that Solomon believed his client had mental problems, such problems do not necessarily mean a defendant is incompetent to enter a plea; moreover Thompson has not identified anything Solomon could have done that would have changed the outcome of the plea proceeding. At the time Thompson was first charged in 1976, four psychiatrists examined him and all four found him competent to stand trial. Nevertheless, Solomon petitioned the court for a new examination to determine Thompson's competence, which request was denied. At the plea proceeding, Thompson brought the possibility of Thompson's incompetence to the trial judge's attention. After interrogating Thompson, the trial judge was satisfied with Thompson's competence to enter a plea. Because we are unaware of any further steps Solomon could have taken to prevent the guilty plea, or to convince the court that Thompson was incompetent, we hold that Thompson's claim of ineffective assistance of counsel at his plea proceeding fails under the prejudice prong of the Strickland test.

B. The Sentencing Hearing

Thompson's claim of ineffective assistance at his sentencing hearing is more difficult. At this hearing the state called police officers, the medical examiner, the victim's mother, and most importantly, Barbara Savage, who related the details of the crime. Solomon did not call any witnesses. Thompson challenges many of Solomon's acts and omissions as falling "outside the wide range of professionally competent assistance." Strickland, 104 S.Ct. at 2066. The district court ruled, however, that Solomon was greatly hindered by Thompson's own actions; specifically, Thompson directed Solomon not to investigate certain matters and refused to testify at the sentencing hearing. Thompson's actions affect both our analysis of whether Solomon was deficient, and whether any deficiencies meet the prejudice standard of Strickland.

1. Failure to Investigate and Present Mitigating Evidence

Thompson's significant allegations that Solomon was ineffective in the sentencing proceeding fall into three categories: failure to investigate and present possible mitigating circumstances; failure to move for a continuance when Thompson refused to testify; the closing argument, which Thompson contends did more harm than good.

A criminal defense attorney has a duty to investigate, but this duty is limited to reasonable investigation. Strickland, 104 S.Ct. at 2066. Thompson alleged several areas of investigation ignored by counsel: among others, Solomon did not investigate the background of the codefendant Surace, and Solomon neither contacted the psychiatrists who had examined Thompson in 1976 nor considered offering the psychiatric reports into evidence. In these two respects, we agree that Solomon's performance was insufficient. In a capital case, where a defendant's life may well depend on the extent and nature of his participation, the background of a codefendant could be crucial. Here, one of Solomon's goals was to affix blame for the crime on Surace, and his failure to investigate Surace's background is, therefore, not understandable. Under the Florida capital statute, psychiatric expertise is relevant to certain statutory mitigating factors. See Fla. Stat.Ann. § 921.141(6). Moreover, Solomon testified in the district court that he thought Thompson was retarded; hence his failure to contact the examining psychiatrists or make any other effort to present Thompson's limited mental capacity to the jury is inexplicable.

Thompson also contends that Solomon was ineffective for failing to investigate Thompson's own background, including childhood and early family life, school records, and service records. Solomon, however, testified in the district court that Thompson directed him not to investigate his past. In Strickland, the Supreme Court noted the importance of the defendant's communications with his attorney in scrutinizing the attorney's decision whether to investigate. 104 S.Ct. at 2066. The Court stated that "when a defendant has given counsel reason to believe that pursuing certain investigations would be fruitless or even harmful, counsel's failure to pursue those investigations may not later be challenged as unreasonable." Id. Nonetheless, Thompson contends that Solomon should not have heeded his request because Solomon was aware that Thompson was experiencing mental difficulties.

This court addressed a similar issue in Mitchell v. Kemp, 762 F.2d 886, 889-90 (11th Cir. 1985). In Mitchell, counsel did not investigate a capital defendant's background, in part because the defendant directed him to leave his family "out of it." 762 F.2d at 889. Although the court found that counsel was not ineffective, it noted that the attorney did not blindly follow Mitchell's instructions: the attorney did not probe deeply into Mitchell's reasons for not wishing to involve his family, but did make an independent evaluation of character witnesses by an in-depth conversation with Mitchell. Id. at 890. The new Fifth Circuit also has held that although a capital defendant's stated desire not to use character witnesses does not negate the counsel's duty to investigate, it limits the scope of the investigation required. Gray v. Lucas, 677 F.2d 1086, 1093-94 (5th Cir. 1982), cert. denied, 461 U.S. 910, 103 S.Ct. 1886, 76 L.Ed.2d 815 (1983); see also Martin v. Maggio, 711 F.2d 1273, 1280 (5th Cir. 1983) (defendant's "instruction that his lawyers obtain an acquittal or the death penalty did not justify his lawyer's failure to investigate the intoxication defense. . . . Uncounselled jailhouse bravado, without more, should not deprive a defendant of his right to counsel's better-informed advice."), cert. denied, ___ U.S. ___, 105 S.Ct. 447, 83 L.Ed.2d 373 (1984).

The reason lawyers may not "blindly follow" such commands is that although the decision whether to use such evidence in court is for the client, Foster v. Strickland, 707 F.2d 1339, 1343 (11th Cir. 1983) (lawyer bound by client's counselled decision to not rely on insanity defense), cert. denied, 466 U.S. 993, 104 S.Ct. 2375, 80 L.Ed.2d 847 (1984) the lawyer first must evaluate potential avenues and advise the client of those offering possible merit. Here, Solomon did not evaluate potential evidence concerning Thompson's background. Thompson had not suggested that investigation would be fruitless or harmful; rather, Solomon's testimony indicates that he decided not to investigate Thompson's background only as a matter of deference to Thompson's wish. Although Thompson's directions may have limited the scope of Solomon's duty to investigate, they cannot excuse Solomon's failure to conduct any investigation of Thompson's background for possible mitigating evidence. Solomon's explanation that he did not investigate potential mitigating evidence because of Thompson's request is especially disturbing in this case where Solomon himself believed that Thompson had mental difficulties. An attorney has expanded duties when representing a client whose condition prevents him from exercising proper judgment. See Code of Professional Responsibility EC 7-12 (Fla.Stat.Ann. 1983). We conclude that Solomon's failure to conduct any investigation of Thompson's background fell outside the scope of reasonably professional assistance.

Solomon's plan at the hearing was to elicit certain mitigating circumstances through cross-examination, call Thompson, who would express his remorse, and in closing, plead to the jury for mercy. Solomon testified, however, that when the time came for Thompson to take the stand, Thompson refused, stating that he was afraid of making a fool of himself before the jury. Solomon urged Thompson to testify, but Thompson was adamant. Two days later, Thompson did take the stand, at Surace's trial. There Thompson took the majority of blame for the torture-murder himself, deflecting blame from Surace.

The petitioner contends that when he refused to testify, Solomon should have moved for a continuance to determine the basis of his refusal. Although Thompson now claims that he refused to testify because of threats from Surace, according to Solomon, Thompson did not mention these threats until after the sentencing was complete; Thompson's explanation at the time was that he did not want to make a fool of himself. Solomon had prepared Thompson to testify, and he urged Thompson to do so. The ultimate decision whether to testify is for the defendant, and a defendant who rejects his lawyer's advice on such a matter may not later challenge the lawyer's effectiveness. Foster v. Strickland, 707 F.2d 1339, 1343 (11th Cir. 1983). Faced with Thompson's sudden refusal to testify, Solomon apparently made a decision to carry on with the remainder of his presentation. In light of Thompson's adamant position, Solomon's decision to go forward as best he could under the circumstances was not outside the bounds of reasonably professional assistance.

Our conclusion that aspects of Solomon's representation fell outside the range of reasonably professional assistance requires addressing the prejudice prong of the Strickland test. In discussing the showing a petitioner must make to obtain a new trial on the ground of errors by counsel, the Supreme Court specifically rejected an "outcome-determinative standard," 104 S.Ct. at 2068, under which the petitioner would have to prove by a preponderance of the evidence that the result would have been different had the petitioner been provided reasonably effective representation. Instead the Court set forth a standard under which:

The defendant must show that there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome.

Id. Thompson presented considerable evidence at the district court hearing. We must first consider what portion of this evidence could have been presented and argued at the sentencing hearing by a reasonably effective counsel, and then whether such evidence may have been persuasive to a jury. We also must review the evidence actually presented to the sentencing jury, because a "conclusion only weakly supported by the record is more likely to have been affected by errors than one with overwhelming record support." Id. at 2069. If we are confident that the jury still would have concluded that the balance of aggravating and mitigating circumstances warranted death, then the petitioner cannot obtain relief. Id.

The evidence of Thompson's background presented to the district court consisted mostly of his Marine Corps and school records. The Marine Corps records indicate that Thompson was dishonorably discharged for a misrepresentation on his enlistment papers: he stated that he had not committed homosexual acts when in actuality he had a significant history of homosexual conduct. Thompson's elementary school records include grades, teacher comments, evaluations by the school psychologist, and intelligence test scores. They indicate that he was mildly retarded, had poor motor skills, had great difficulty in basic subjects of reading, writing and arithmetic, was hyperactive, and difficult.

Thompson also proffered the psychiatric evaluations prepared in 1976 and ignored by Solomon; these exhibits further document Thompson's troubled early years. They indicate Thompson left school in the ninth grade at the age of eighteen, that he had had difficulty getting along with his parents, and that he had been a drug abuser. All four psychiatrists who examined Thompson in 1976 concluded that he was sane at the time of the offense and that he was capable of assisting in his defense. This does not mean, however, that no psychiatric mitigating factors, statutory or nonstatutory, were indicated in the reports. Three of the psychiatrists diagnosed Thompson as having a personality disorder; the fourth questioned the extent of Thompson's participation in the crime due to possible intoxication and drug use.

Finally, Thompson contends that reasonable investigation of Surace would have revealed that Surace was involved with violent motorcycle gangs, had been convicted of intimidating a government witness, and at age fourteen had killed a playmate. In sum, reasonable investigation would have yielded evidence of Thompson's low intelligence and troubled past and the violent reputation of his codefendant.

Even had the jury heard this evidence, however, we are confident that Thompson's sentence would have been the same. The jury's determination was strongly supported by the aggravating circumstances introduced in the record. Nothing Solomon could have presented would have rebutted the testimony concerning Thompson's participation in the brutal torture murder. The testimony indicated that although Surace initiated the beatings, Thompson took over, beating the victim with a chain, his fist, a chair leg, and a billy club. The testimony also indicated that it was Thompson who actually raped the victim with the chair leg and billy club. After hearing testimony that Thompson committed these atrocities, the jury heard nothing from Thompson himself in reply. As noted above, Thompson, and not Solomon, was responsible for his failure to testify. We do not believe that there is a reasonable probability that evidence of a difficult youth, an unsavory codefendant, and limited mental capacity would have altered this jury's decision.

Furthermore, the evidence offered in the district court would not be particularly persuasive even had the crime been less egregious. Barbara Savage testified at the trial as to Surace's connection with motorcycle gangs and that Thompson was following Surace's lead throughout the incident, and Solomon argued this point to the jury. With respect to Thompson's mental condition, which was not touched upon at the sentencing hearing, although the psychiatric reports suggested a personality disorder, and the school records indicated low intelligence, none of the material indicated that Thompson was suffering any specific disturbance at the time of the crime which would have mitigated his participation. Finally, although Thompson's difficulties in his early years were ignored at the sentencing hearing, he has produced no witnesses, and we doubt that the jury would have found mere copies of school records particularly persuasive.

2. Closing Argument

Thompson also attacks Solomon's closing argument, set forth in the margin. Thompson contends that Solomon unnecessarily stressed the horror of the crime, and that he should not have referred to his court-appointed status. This court has previously condemned references to court-appointed status, arguing that such references "effectively stack the odds against the accused." Goodwin v. Balkcom, 684 F.2d 794, 805-06 (11th Cir. 1982), cert. denied, 460 U.S. 1098, 103 S.Ct. 1798, 76 L.Ed.2d 364 (1983). In King v. Strickland, 714 F.2d 1481, 1491 (1983), reinstated, 748 F.2d 1462 (11th Cir. 1984), cert. denied, ___ U.S. ___, 105 S.Ct. 2020, 85 L.Ed.2d 301 (1985), this court granted relief on a claim of ineffective assistance of counsel based in part on a closing argument which "did more harm than good." 748 F.2d at 1464.

Counsel representing a defendant in a death case is in a difficult position, and Solomon's failure to present any mitigating evidence made the task even more difficult. Where, as here, the defendant has pleaded guilty, counsel can hardly make a credible closing argument asking for mercy without acknowledging the crime; nor can he ignore the defendant. Thompson argues that Solomon's discussion of Thompson as a "loser" and of the heinous nature of the crime, went far beyond the need to maintain credibility. In this case, Solomon may have gone beyond what was necessary. We decline, however, to further critique the closing; reviewing courts must not unnecessarily "grade counsel's performance," Strickland v. Washington, 104 S.Ct. at 2070, and this admonition seems particularly compelling in the case of closing argument, an inherently subjective task. Here, in light of the overwhelming evidence of aggravating circumstances, we believe that Thompson has failed to show a reasonable probability that the closing argument, even considered together with Solomon's failure to present mitigating evidence, changed the outcome. We therefore need not determine whether the argument met the standard of reasonably professional assistance. 104 S.Ct. at 2070.

In only one case, King v. Strickland, have we relied on counsel's closing argument to grant relief under the Strickland v. Washington standard. The closing argument in King is in one respect similar to the argument in this case; both counsel referred to their court-appointed status. In King, however, counsel in effect apologized to the jury for representing such a horrible person, 714 F.2d 1491, and totally disassociated himself from his client. Solomon's reference to his status was in an attempt to evoke sympathy for his client, and Solomon did not attempt to disassociate himself from Thompson. More important, King's conviction, unlike Thompson's was based on circumstantial evidence, and such convictions always present a better case for mercy to the sentencing jury. 748 F.2d at 1464.

In sum, the overwhelming evidence of aggravating circumstances convinces us that there is not a reasonable probability that the jury would have changed its sentencing conclusion had Solomon presented and argued the mitigating evidence now offered, and Thompson's claim of ineffective assistance at his sentencing hearing therefore must fail under the prejudice prong of Strickland v. Washington.

II. RESTRICTION ON MITIGATING EVIDENCE

A. Nonstatutory Evidence

Thompson contends that the trial court restricted consideration of non-statutory mitigating factors in violation of Lockett v. Ohio, 438 U.S. 586, 606-08, 98 S.Ct. 2954, 2965-67, 57 L.Ed.2d 973 (1978). He argues that the jury instructions, coupled with objections the judge sustained when Solomon attempted to advise the jury that they were not limited to statutory mitigating circumstances and when he sought to elicit testimony that Thompson was taking drugs at the time of the crime, all indicate that evidence of non-statutory mitigating circumstances was restricted.

The district court found that Thompson had presented this claim to the Florida courts on direct appeal and therefore considered it on the merits and denied relief. Based on the briefs and opinions in Thompson's state appeal, the state contends that the issue was not presented on Thompson's direct appeal and asks that we apply procedural default to the claim. See Ford v. Strickland, 696 F.2d 804, 816-17 (11th Cir. 1983) (en banc) (Florida rule that all grounds must be raised on direct appeal adequate reason to bar federal review). The state argues that although it has waived exhaustion of the claim, it has not and does not waive procedural default. This argument raises difficult questions. First, we note that the Lockett claim was one of the original claims in Thompson's petition, filed on February 24, 1982. Not until July 9, 1984, the day of the evidentiary hearing, did the state first assert that the claim had not been presented to the state courts. Moreover, at no time did the state file a motion to dismiss the claim. In the meantime, the district court had held a hearing on whether to continue its consideration of the petition, this court had entertained an interlocutory appeal, the state had offered an unconditional waiver of exhaustion, and the district court had exercised its discretion to accept that waiver. Throughout this time (February 24, 1982 — July 9, 1984), the parties acted under the assumption that the claims in the original petition had been presented to the Florida courts. See, e.g., Jenkins v. Andersen, 447 U.S. 231, 100 S.Ct. 2124, 2127 n. 1, 65 L.Ed.2d 86 (state may waive procedural default by not asserting it in a timely manner). Second, the state's offer of a waiver of exhaustion was unconditional. Now the state requests that the federal courts apply procedural default, a state law ground of decision, to a claim in the petition. The district court's acceptance of the waiver was discretionary, and had the court been told that the state wished the court to apply a state law ground of decision, the district court may well have chosen to decline the state's waiver. See Thompson v. Wainwright, 714 F.2d 1495, 1508-09 (district court should decline waiver of exhaustion if undecided questions of state law exist). Accordingly, it seems quite possible that the state has waived procedural default. We need not decide this question, however, because the district court was clearly correct in declining Thompson relief on the merits of his Lockett claim.

This court recently has described the method for analyzing Lockett claims such as the one advanced by Thompson. Hitchcock v. Wainwright, 770 F.2d 1514 (11th Cir. 1985) (en banc). A court should consider all the circumstances, including the status of Florida law at the time of sentencing, the trial record, and proffers of nonstatutory mitigating evidence claimed to be available. 770 F.2d at 1517. Here, at the time of sentencing, the confusion in Florida law had partially been alleviated by Lockett, but the Florida Supreme Court had not yet issued its clarifying opinion in Songer v. State, 365 So.2d 696, 699 (Fla. 1978). Solomon, however, did not proffer any nonstatutory mitigating evidence at the sentencing hearing. Solomon also testified in the district court that in preparing for the sentencing hearing he did not feel constrained by Florida law in investigating nonstatutory mitigating circumstances.

Solomon did testify that he felt constrained when the trial court sustained objections to questions about alcohol and drug use by Thompson and Surace, and the record of the sentencing proceeding indicates that the court did limit cross-examination on this point. For example, Savage was not allowed to answer Solomon's question whether they were taking any pills. Thompson, however, did not proffer, either at trial or in the district court hearing, what the witness would have answered. Furthermore, in her pretrial deposition Savage did not state that Thompson was taking drugs, although she did indicate that Thompson and Surace were drinking heavily on the day of the crime, and this fact came out in other testimony. We conclude therefore that Thompson has not shown any excluded evidence that could have affected the sentence. The testimony introduced at the sentencing hearing indicated that at the time of the crime Thompson was well able to communicate, and that he and Surace concocted an alibi story. Accordingly, we find that additional evidence regarding intoxication would have been cumulative and would not have made a difference to the sentencing jury.

In sum, with respect to nonstatutory mitigating circumstances, we conclude that Thompson did not proffer any significant nonstatutory mitigating circumstances either at sentencing or at the district court's evidentiary hearing and that his claim must therefore be denied.

B. Statutory Mitigating Evidence

Thompson also contends that the trial court excluded evidence of statutory mitigating circumstances; specifically he argues that the court limited cross-examination intended to show that he was under the influence of an extreme emotional disturbance. Fla.Stat.Ann. § 921.141(6)(b). The only testimony Thompson claims was excluded, however, was Savage's response to questions concerning whether Thompson intended the beating to kill the victim. The trial judge did not rule that the testimony was irrelevant; rather he ruled that the witness could not testify to the subjective intentions of another person, and Thompson does not argue that this ruling was improper under the Florida rules of evidence. Lockett entitles a capital defendant to introduce all relevant mitigating evidence at sentencing, but does not require a state to abandon its rules of evidence concerning what is competent testimony. Cf. Martin v. Wainwright, 770 F.2d 918, 938 (11th Cir. 1985) ( Lockett does not abrogate Florida evidentiary rule which prevented defendant from admitting selected portions of documents without admitting entire document).

III. WHETHER THE COURT SHOULD HAVE FURTHER INQUIRED INTO THOMPSON'S COMPETENCY TO STAND TRIAL

Thompson contends that the trial court should have conducted a hearing into his competency to stand trial. A court that has a bona fide doubt of the defendant's competency to stand trial must sua sponte conduct a hearing to consider that issue. Pate v. Robinson, 383 U.S. 375, 385, 387, 86 S.Ct. 836, 842, 843, 15 L.Ed.2d 815 (1966); Hance v. Zant, 696 F.2d 940, 948 (11th Cir.), cert. denied, 463 U.S. 1210, 103 S.Ct. 3544, 77 L.Ed.2d 1393 (1983). The test for competency to stand trial is: whether the defendant "has sufficient present ability to consult with his lawyer with a reasonable degree of rational understanding — and whether he has a rational as well as factual understanding of the proceedings against him." Dusky v. United States, 362 U.S. 402, 402, 80 S.Ct. 788, 789, 4 L.Ed.2d 824 (1960). The district court found that no doubt had been raised of Thompson's competency.

Three factors should be considered in determining whether the trial court violated Pate by not conducting a hearing on competency: (1) evidence of the defendant's irrational behavior; (2) his demeanor at trial; and (3) any prior medical opinion on his competency to stand trial. Drope v. Missouri, 420 U.S. 162, 180, 95 S.Ct. 896, 908, 43 L.Ed.2d 103 (1975). Before the first plea proceeding in 1976, Thompson was examined by four psychiatrists, and all four found him competent to stand trial. Thompson filed a new motion for examinations in connection with the 1978 plea proceeding, but as the Supreme Court of Florida noted, nothing in the motion indicated any "circumstance that had caused the mental condition of the appellant to change since those prior examinations." 389 So.2d at 199.

Thompson contends that his responses during the trial judge's interrogation at the plea proceeding raised a doubt as to his competency. The trial judge interrogated Thompson regarding any past mental problems, and whether he understood the proceedings and the ramifications of pleading guilty. Thompson points to one response as raising a doubt: when the court asked Thompson if he had been employed in the past two years, Thompson answered yes; in fact, Thompson had spent the prior two years in either the county jail or on death row. This one incorrect response, however, hardly indicates that Thompson was incompetent. Thompson correctly answered numerous questions from the judge, and we conclude that there was no need for the judge to further inquire into Thompson's competency.

IV. AKE CLAIM

Before the sentencing proceeding, Solomon requested that the court appoint experts to conduct psychiatric and neurological examinations of Thompson. The trial court denied these requests and the Florida Supreme Court affirmed. 389 So.2d at 199. In his habeas petition, Thompson contends that the denial of psychiatric assistance unconstitutionally restricted the presentation of mitigating circumstances. Subsequent to the district court's ruling on the petition, the Supreme Court decided Ake v. Oklahoma, ___ U.S. ___, 105 S.Ct. 1087, 84 L.Ed.2d 53 (1985), in which it established a limited right to court-appointed psychiatric assistance in presenting a defense. We now evaluate Thompson's claim in light of Ake.

In Ake, the Supreme Court considered an indigent defendant's need for psychiatric assistance both at trial and at the death penalty sentencing hearing. With respect to guilt or innocence, the Court held

that when a defendant demonstrates to the trial judge that his sanity at the time of the offense is to be a significant factor at trial, the State must, at a minimum, assure the defendant access to a competent psychiatrist who will conduct an appropriate examination and assist in evaluation, preparation, and presentation of the defense.

Id., 105 S.Ct. at 1097.

Thompson's claim on appeal, however, is limited to the sentencing phase and the Court's discussion in Ake of the need for psychiatric assistance in capital sentencing proceedings was somewhat different. The Court focused on the fact that certain states place before the jury psychiatric evidence of a defendant's future dangerousness, and that the Court had approved such a practice. Id. at 1097 (quoting Barefoot v. Estelle, 463 U.S. 880, 896-905, 103 S.Ct. 3383, 3395-3400, 77 L.Ed.2d 1090 (1983)). The Court held:

In such a circumstance, where the consequence of error is so great, the relevance of responsive psychiatric testimony so evident, and the burden on the State so slim, due process requires access to a psychiatric examination on relevant issues, to the testimony of the psychiatrist, and to assistance in preparation at the sentencing hearing.

Id., 105 S.Ct. at 1097.

The motion filed with the trial court stated that counsel believed Thompson suffered from a mental defect "which would render him incapable of assisting in his defense, and may have precluded the Defendant from knowing right from wrong at the time of the alleged criminal acts." The trial court heard the motion, and again no mention was made of mitigating circumstances. Because Thompson did not request psychiatric assistance to aid in presenting mitigating circumstances, Ake does not apply. Bowden v. Kemp, 767 F.2d 761, 764; Bowden v. Francis, ___ U.S. ___, 105 S.Ct. 1834, 1834-35, 85 L.Ed.2d 135 (1985) (O'Connor, J., dissenting from remand to court of appeals in light of Ake). We hold therefore that Ake did not require appointment of a psychiatrist at the sentencing phase.

Thompson did argue in his motion for a new trial and his brief on direct appeal to the Florida Supreme Court that the denial of psychiatric assistance limited the development of mitigating circumstances. Ake, however, requires appointment of psychiatric assistance only where a showing of need is made before trial. 105 S.Ct. at 1097.

V. COERCION OF THOMPSON'S PLEA

Finally Thompson contends that his decision to plead guilty, and to testify on behalf of Surace was not voluntary, but was coerced by threats from Surace. Thompson presented this claim to the Florida courts in a motion for collateral relief. The state trial court found Thompson's affidavit not credible, and refused to hold a hearing. The Florida Supreme Court affirmed. 410 So.2d 500 (1982).

At the district court hearing, Thompson testified that he was coerced into pleading guilty and testifying for Surace. He explained that while he and Surace were being held together in 1978, Surace told Thompson to take credit for the killing or Surace would have him killed, and Thompson testified that he believed Surace could do this based on Surace's membership in motorcycle gangs and Surace's comrades in prison. Thompson introduced no evidence to corroborate this testimony, other than a stipulation by the state that at the time of Thompson's second plea, Thompson and Surace were transported to the county courthouse together and held in the same cell while in the courthouse, and testimony of Thompson's trial lawyers that Surace used Thompson as his "tool" and before the second plea proceeding Surace's counsel was attempting to convince Thompson to commit perjury. Surace testified in the district court and denied Thompson's allegations. After hearing the testimony, the district court found that Thompson had not met his burden of proof, in effect finding that Thompson's testimony was not credible.

Although Thompson challenges the voluntariness of his plea as a ground on appeal, he provides no legal arguments in his brief. As stated above, based upon Thompson's affidavit attached to his pleadings in the collateral proceeding, the state courts found his claim incredible and held no hearing. The district court received evidence on the claim at the evidentiary hearing, but in its order denying relief ruled that Thompson had not met his burden under section 2254 of proving that the conclusion of the state court on collateral review was erroneous. The effect of the section 2254 presumption was that Thompson was required to present convincing evidence that his plea was not voluntary; normally, a habeas petitioner need only demonstrate by a preponderance of the evidence that he is entitled to relief. 28 U.S.C. § 2254(c); Thomas v. Zant, 697 F.2d 977, 986 (11th Cir. 1983). The district court's understanding of section 2254 was mistaken. Section 2254(d) does provide that a federal court considering a habeas petition must afford a presumption of correctness to state court factual findings, but only if the findings were made "after a hearing on the merits of a factual issue," and that hearing must meet the requirements set forth in section 2254(d)(1)-(8). Here the state court refused to hold such a hearing, and thus the findings of the state courts in the collateral proceeding are not entitled to a presumption of correctness.

Nevertheless, we do not believe that a remand is necessary. Although the state courts did not hold a hearing on collateral review, the state trial court held an adequate hearing on Thompson's plea at the time it was entered. The transcript of that proceeding is part of the record. The trial court placed Thompson under oath, and specifically inquired:

THE COURT: Has any persons [sic] used any threat, force, pressure, intimidation, or promised anything to you for the purpose of getting you to plead guilty to these charges?

THE DEFENDANT: No, Sir.

THE COURT: Are you doing it voluntarily?

THE DEFENDANT: Voluntarily, sir.

The state trial court then announced that it found that Thompson's "decision to plead guilty has been made freely, voluntarily, and intelligently."

In Blackledge v. Allison, 431 U.S. 63, 97 S.Ct. 1621, 52 L.Ed.2d 136 (1977), the Supreme Court stated that "the representations of the defendant [at a plea hearing] as well as any findings made by the judge accepting the plea, constitute a formidable barrier in any subsequent collateral proceedings." 97 S.Ct. at 1629. The Court further ruled that the petitioner's "declarations in open court carry a strong presumption of verity." Id. In Moya v. Estelle, 696 F.2d 329 (5th Cir. 1983), the habeas petitioner contended that his own attorney had intimidated him into pleading guilty. The new Fifth Circuit held that in light of the petitioner's sworn statement at the plea proceeding that he had not been threatened and that he was satisfied with counsel, no evidentiary hearing was necessary on his claim in a federal habeas proceeding. 696 F.2d at 332-33. See also, Rogers v. Maggio, 714 F.2d 35, 38 n. 5 (5th Cir. 1983).

Here, Thompson testified under oath that his plea was not coerced, and the state trial court so concluded. The district court in effect gave these findings a presumption of correctness. We see little difference between the presumption of correctness under section 2254 and the "strong presumption of verity" identified by the Supreme Court in Blackledge. Accordingly, the district court was correct in requiring Thompson to present convincing evidence that his plea was not voluntary and the district court's conclusion that Thompson failed to meet this burden is not clearly erroneous.

CONCLUSION

For the foregoing reasons, the order of the district court denying Thompson's petition for a writ of habeas corpus is

AFFIRMED.
