Defendant's guilty pleas were knowing, intelligent, and voluntary. By pleading guilty, defendant waived any claim that his right to testify before the Grand Jury was violated ( People v McConville, 188 AD2d 358, lv denied 81 NY2d 843), and the court was under no obligation to specifically advise defendant of that consequence of his plea ( see, People v Harris, 61 NY2d 9). In view of defendant's advantageous plea bargain, defendant was provided with meaningful representation ( People v Ford, 86 NY2d 397, 404; People v Rivera, 223 AD2d 400, lv denied 88 NY2d 969).
