CARLEY, Justice.

Appellant was indicted on alternative counts of malice murder and felony murder in the commission of an aggravated assault. He pled not guilty by reason of insanity and was brought to trial before a jury. Although the trial court charged, at appellant's request, on voluntary manslaughter, he was found guilty of both malice murder and felony murder. The trial court merged the two convictions and sentenced appellant to life. Appellant's motion for new trial was denied and he appeals.

1. On appeal, appellant urges that a portion of closing argument by counsel for the State was violative of OCGA § 17-8-76. However, no objection was raised below. " Upon objection to argument which contravenes [OCGA § 17-8-76], a mistrial is mandatory." (Emphasis supplied.) Gilreath v. State, 247 Ga. 814, 835 (15) ( 279 S.E.2d 650) (1981).

Moreover, an objection predicated upon OCGA § 17-8-76 would have been meritless. The contested argument occurred in the context of an attack by counsel for the State upon the credibility of testimony that had been given by appellant's expert. OCGA § 17-8-76 (a) bars argument "that a defendant, if convicted, may not be required to suffer the full penalty imposed by the court or jury because pardon, parole, or clemency of any nature may be granted...." Since counsel for the State was merely attacking the credibility of testimony and she "did not specifically refer to pardon, parole, or other clemency, the statute was not contravened, and the trial court was not required to declare a mistrial. [Cits.]" Romine v. State, 256 Ga. 521, 533 (10) ( 350 S.E.2d 446) (1986).

2. In his motion for new trial, appellant raised the issue of the effectiveness of his trial counsel. The trial court found that appellant's trial counsel had not been ineffective. On appeal, appellant urges that the trial court erred in denying the motion for new trial on this ground.

The allegations of ineffectiveness relate to the manner in which appellant's trial counsel dealt with the expert who was proffered by the State. The record demonstrates, however, that the State's expert was subjected to a thorough and sifting cross-examination.

While other counsel, had they represented appellant, may have exercised different judgment, the fact that the trial counsel chose to try the case in the manner in which it was tried and made certain difficult decisions regarding the defense tactics to be employed with which appellant and his present counsel now disagree, does not require a finding that the representation below was so inadequate as to amount to a denial of effective assistance of counsel. [Cit.]

Solomon v. State, 247 Ga. 27, 29 (1) ( 277 S.E.2d 1) (1981).

[T]he constitutional right to assistance of counsel [means] "not errorless counsel, and not counsel judged ineffective by hindsight, but counsel reasonably likely to render and rendering reasonably effective assistance." [Cit.]

Hawes v. State, 240 Ga. 327, 329 (1) ( 240 S.E.2d 833) (1977).

3. Appellant urges that his conviction must be reversed because the trial court gave a "sequential" charge contrary to the mandate of Edge v. State, 261 Ga. 865 (2) ( 414 S.E.2d 463) (1992).

The intent of Edge, supra at 867 (2), is to preclude "a felony murder conviction . . . where [such a conviction] would prevent an otherwise warranted verdict of voluntary manslaughter." (Emphasis supplied.) Thus, the giving of a "sequential" charge may be reversible error in a case wherein the jury must determine whether a homicide is felony murder or voluntary manslaughter.

The "sequential" charge eliminates the jury's full consideration of voluntary manslaughter because, if it concludes a felony murder occurred, it would not then go on to consider evidence of provocation or passion which might authorize a verdict for voluntary manslaughter. Instead, the trial court should instruct the jury so as to ensure adequate consideration of charges for both [felony murder and voluntary manslaughter].

(Emphasis supplied.) Edge v. State, supra at 867 (2).

In the instant case, appellant was found guilty of malice murder, as well as the alternative count of felony murder. Accordingly, any error in the giving of a "sequential" charge in connection with felony murder and voluntary manslaughter clearly would be harmless. Voluntary manslaughter could not have been eliminated from the jury's consideration by virtue of the "sequential" charge. Voluntary manslaughter was eliminated from the jury's consideration by its finding that appellant was guilty of malice murder. "Intent to kill is an essential element of both murder and voluntary manslaughter. [Cits.] Provocation, or the lack thereof, is what distinguishes the two offenses." Parks v. State, 254 Ga. 403, 414 (12) ( 330 S.E.2d 686) (1985). By finding that appellant had committed the homicide with malice, the jury necessarily found that appellant had committed the homicide without the provocation sufficient to authorize a verdict of guilty of voluntary manslaughter. "`It is the absence of malice [and the presence of sufficient provocation] which differentiates manslaughter from murder.'" Parker v. State, 218 Ga. 654, 658 (5) ( 129 S.E.2d 850) (1963).

Moreover, Edge, supra at 867 (2), holds that a "sequential" charge "is not appropriate where there is evidence that would authorize a charge on voluntary manslaughter." "The evil which Edge seeks to cure is not present in the case before us." Stewart v. State, 262 Ga. 894 ( 426 S.E.2d 367) (1993). In the instant case, the trial court did charge on voluntary manslaughter, but a review of the transcript demonstrates that the evidence would not authorize that charge. Under the evidence, appellant was either guilty of murder or not guilty by reason of insanity. According to appellant's own testimony, "there was no exact reason" why he stabbed the victim, he "lost it," and "didn't purposefully do it." There being no evidence that appellant's act of stabbing the victim to death was his intentional response to sufficient provocation on her part, the jury would not have been authorized to find that the homicide was an act of voluntary manslaughter. Accordingly, the trial court's error was not in giving a "sequential" charge in connection with felony murder and voluntary manslaughter, but in giving any charge whatsoever on voluntary manslaughter as a possible offense for which appellant could be convicted.

4. Construed most favorably for the State, the evidence was sufficient to authorize a rational trier of fact to find proof of appellant's guilt beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307 ( 99 S.C. 2781, 61 L.Ed.2d 560) (1979).

Judgment affirmed. All the Justices concur.
