Is a mere conclusory allegation insufficient to prove that counsel was ineffective?

Mere conclusory allegations are insufficient to prove that counsel was ineffective. Shah v. United States, 878 F.2d 1156, 1161 (9th Cir.1989). A habeas petitioner is entitled to an evidentiary hearing or habeas relief when "he has alleged facts [in his petition] which, if proven, would entitle him to relief.... Notice pleading is not sufficient, for the petition is expected to state facts that point to a real possibility of constitutional error." O'Bremski v. Maass, 915 F.2d 418, 420 (9th Cir.1990) (quotations omitted).
