Is there any case law where a reasonably competent attorney advised a defendant to admit prior convictions that qualify as a strike?

In the situation before us, a reasonably competent attorney would be informed of the types of prior convictions that qualify as strikes and advise his or her client of the applicable law in any discussion of an admission. (See People v. McCary (1985) 166 Cal.App.3d 1, 7-9.) Walsh points to no place in the record, however, which indicates that trial counsel was not reasonably informed of the facts or law before advising him to admit the priors. (See People v. Vargas (2001) 91 Cal.App.4th 506, 537 [the defendant bears the burden of showing the court that trial counsel's decision to advise defendant to admit the priors was not informed].)
