"It is well established that ineffective assistance of counsel claims 'brought on direct review will be decided on the merits when the cold record reveals that no further investigation is required, i.e., claims that may be developed and argued without such ancillary procedures as the appointment of investigators or an evidentiary hearing.' Thus, when this Court reviews ineffective assistance of counsel claims on direct appeal and determines that they have been brought prematurely, we dismiss those claims without prejudice, allowing defendant to bring them pursuant to a subsequent motion for appropriate relief in the trial court. State v. Thompson, 359 N.C. 77, 122-23, 604 S.E.2d 850, 881 (2004) (citation omitted) (quoting State v. Fair, 354 N.C. 131, 166, 577 S.E.2d 500, 524 (2001)), cert. denied, 546 U.S. 830, 163 L. Ed. 2d 80 (2005).
"To prevail on a claim of ineffective assistance of counsel, a defendant must first show that his counsel's performance was deficient and then that counsel's deficient performance prejudiced his defense. Deficient performance may be established by showing that counsel's representation fell below an objective standard of reasonableness. Generally, to establish prejudice, a defendant must show that there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome. State v. Allen, 360 N.C. 297, 316, 626 S.E.2d 271, 286 (citations and quotation marks omitted), cert. denied, 549 U.S. 867, 166 L. Ed. 2d 116 (2006).
"Decisions concerning which defenses to pursue are matters of trial strategy and are not generally second-guessed by this Court. State v. Prevatte, 356 N.C. 178, 236, 570 S.E.2d 440, 472 (2002), cert. denied, 538 U.S. 986, 155 L. Ed. 2d 681 (2003).
