Before: PETERS, P.J., GARRY, MULVEY, AARONS and PRITZKER, JJ.
PRITZKER, J.In full satisfaction of a three-count indictment, defendant pleaded guilty to one count of robbery in the second degree and waived his right to appeal. Although defendant subsequently moved—both pro se and with newly assigned counsel—to vacate his plea, defendant ultimately withdrew that motion and thereafter was sentenced in accordance with the terms of the revised plea agreement to 10 years in prison followed by five years of postrelease supervision—said sentence to be served concurrently with the sentence defendant then was serving. This appeal by defendant ensued.We affirm. To the extent that defendant's brief may be read as challenging the validity of his waiver of the right to appeal, we find this claim to be unpersuasive. Defendant was advised that an appeal waiver was a condition of the plea agreement, County Court distinguished the waiver of appeal from the trial-related rights that defendant was forfeiting, defendant executed a written waiver of appeal in open court and, in response to questioning by the court, defendant confirmed his understanding of the waiver. Under these circumstances, we are satisfied that defendant's combined oral and written appeal waiver was knowing, intelligent and voluntary (see People v. Hall, 147 A.D.3d 1151, 1151, 47 N.Y.S.3d 147 [2017], lv. denied 29 N.Y.3d 1080, 64 N.Y.S.3d 170, 86 N.E.3d 257 [2017] ; People v. Dolberry, 147 A.D.3d 1149, 1150, 46 N.Y.S.3d 437 [2017], lv. denied 29 N.Y.3d 1078, 64 N.Y.S.3d 167, 86 N.E.3d 254 [2017] ).
Although defendant's challenge to the voluntariness of his plea survives his As for defendant's ineffective assistance of counsel claim, certain of the arguments now advanced-including counsel's alleged failure to adequately explore potential defenses and sufficiently explain the various options available to defendant-implicate matters outside of the record and, as such, are more properly considered in the context of a CPL article 440 motion (see People v. Breault, 150 A.D.3d 1548, 1549, 52 N.Y.S.3d 683 [2017] ; People v. Franklin, 146 A.D.3d 1082, 1084, 45 N.Y.S.3d 635 [2017], lvs. denied 29 N.Y.3d 946, 948, 54 N.Y.S.3d 377, 379, 76 N.E.3d 1080, 1082 [2017] ). To the extent that the balance of this claim impacts upon the voluntariness of defendant's plea, "such claim survives his valid appeal waiver but is unpreserved for our review in the absence of an appropriate postallocution motion" ( People v. Lewis, 143 A.D.3d 1183, 1185, 40 N.Y.S.3d 605 [2016] ). Finally, in light of defendant's valid appeal waiver, his challenge to the severity of his sentence is precluded (see People v. Lambert, 151 A.D.3d 1119, 1120, 55 N.Y.S.3d 526 [2017], lv. denied 29 N.Y.3d 1092, 63 N.Y.S.3d 9, 85 N.E.3d 104 [2017] ; People v. Caldwell, 148 A.D.3d 1468, 1468, 49 N.Y.S.3d 312 [2017] ).
ORDERED that the judgment is affirmed.
PETERS, P.J., GARRY, MULVEY and AARONS, JJ., concur.
