Is there any reason for a defendant to ask for a continuance or a mistrial?

Defendant points to trial counsel's claim that he was in a "pickle" because the more time he spent reviewing the recording the less time he had for other matters, and argues that trial counsel had no reason not to ask for a continuance or a mistrial. But counsel could rationally have concluded the trial was going as well as could be expected because the stipulation was favorable and that it was not necessary to seek a continuance or a mistrial. "Even the best criminal defense attorneys would not defend a particular client in the same way. [Citation.]" (Strickland v. Washington (1984) 466 U.S. 668, 689 [80 L.Ed.2d 674, 695].)
