We find that defendant received effective assistance of counsel. The court properly rejected his postconviction motion alleging ineffective assistance of counsel based on the decision by his trial counsel to withdraw a speedy trial motion, since defendant has failed to demonstrate that this motion, had it been considered, would have been successful ( see, People v. Hobot, 84 N.Y.2d 1021; People v. Robideau, 133 A.D.2d 903, lv denied 71 N.Y.2d 902). The court's findings of excludability are amply supported by the totality of the record, including the parties' submissions, and no evidentiary hearing was necessary ( see, People v. Satterfield, 66 N.Y.2d 796).
Defendant failed to preserve his claim that the People presented excessive, unnecessary and prejudicial background and expert testimony on the methods of operation of drug sellers and we decline to review this claim in the interest of justice. Were we to review this claim, we would find the challenged testimony was necessary to clarify issues beyond the ken of the ordinary juror ( see, People v. Taylor, 75 N.Y.2d 277, 288; People v. Santiago, 243 A.D.2d 328; People v. Kelsey, 194 A.D.2d 248).
The verdict was based on legally sufficient evidence and was not against the weight of the evidence. Issues of credibility were properly presented to the jurors, who saw and heard the witnesses ( People v. Gaimari, 176 N.Y. 84, 94) and we see no reason to disturb their determination. Since there was ample evidence supporting a constructive possession theory (see, People v. Bundy, 90 N.Y.2d 918), that theory was properly submitted to the jury.
We have considered defendant's other contentions and find them to be without merit.
