With no explanation, chose the best option from "A", "B", "C" or "D". has not waived the requirement that the district court exercise discretion. More important, even if the district court does not consider the possibility of denying the motion for self-representation, the court is obliged to assure that the defendant’s waiver of counsel is knowing, voluntary, and intelligent.

And, where a defendant seeks substitute counsel on the basis of a claim that his present counsel is ineffective, a defendant’s waiver of counsel may not be voluntary where the court narrows the defendant’s options to either self-representation or proceeding with his present counsel. See, e.g., Pazden v. Maurer, 424 F.3d 303, 313 (3d Cir.2005); Gilbert v. Lockhart, 930 F.2d 1356, 1360 (8th Cir.1991) (<HOLDING>). At the very least, the court was required to

B: holding that a defendants waiver was invalid where he was required to choose between proceeding with unprepared counsel or no counsel
C: holding that defendants failure to obtain counsel despite opportunities to do so implied a waiver of counsel
D: holding that where trial counsel was not ineffective appellate counsel was not ineffective for failing to raise claim of ineffectiveness of trial counsel
