What is the test for ineffective assistance in a criminal case?

range of reasonable professional assistance. It is particularly difficult to prevail on an appellate claim of ineffective assistance. On direct appeal, a conviction will be reversed for ineffective assistance only if (1) the record affirmatively discloses counsel had no rational tactical purpose for the challenged act or omission, (2) counsel was asked for a reason and failed to provide one, or (3) there simply could be no satisfactory explanation. All other claims of ineffective assistance are more appropriately resolved in a habeas corpus proceeding. [Citations.]" (People v. Mai (2013) 57 Cal.4th 986, 1009.)

"Judicial scrutiny of counsel's performance must be highly deferential. It is all too tempting for a defendant to second-guess counsel's assistance after conviction or adverse sentence, and it is all too easy for a court, examining counsel's defense after it has proved unsuccessful, to conclude that a particular act or omission of counsel was unreasonable. [Citation.] A fair assessment of attorney performance requires that every effort be made to eliminate the distorting effects of hindsight, to reconstruct the circumstances of counsel's challenged conduct, and to evaluate the conduct from counsel's perspective at the time. Because of the difficulties inherent in making the evaluation, a court must indulge a strong presumption that counsel's conduct falls within the wide range of reasonable professional assistance; that is, the defendant must overcome the presumption that, under the circumstances, the challenged action 'might be considered sound trial strategy.' [Citation.]" (Strickland v. Washington (1984) 466 U.S. 668, 689.)
