What is the standard for a successful ineffective assistance of counsel claim?

The Sixth Amendment standard for analyzing an ineffective assistance of counsel claim is well established. To prevail on a claim of ineffective assistance of counsel, a petitioner must show that his trial counsel's performance "fell below an objective standard of reasonableness" and that "there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different." Strickland v. Washington, 466 U.S. 668, 687-88, 694 (1984).
