Sherman Guy pleaded guilty to distributing cocaine base and the district court 1 sentenced him to 120 months imprisonment and 5 years supervised release. On appeal, Guy’s counsel has moved to withdraw and filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), raising the following issues: whether the sentencing court erred in considering cocaine base which formed the basis of other distribution counts that were dismissed, and whether the court erred in determining that Guy was a career offender. In a pro se supplemental brief, Guy reasserts these issues, and also argues that the government breached the plea agreement by failing to object to inclusion of the cocaine base from the dismissed counts in calculating his sentence, the government failed to disclose that he would be sentenced as a career offender, and his counsel was ineffective.

The district court properly sentenced Guy as a career offender. Guy was over 18 years old when he committed the instant controlled-substanee offense, and he previously had been convicted of two controlled-substanee offenses and two crimes of violence. See U.S.S.G. §§ 4B1.1 (career-offender criteria); 4B1.2(a) and (b) (defining crime of violence and controlledsubstanee offense). Thus, his offense level was determined by his career-offender status, not the cocaine base from the dismissed counts. See United States v. Darden, 70 F.3d 1507, 1548 n. 17 (8th Cir. 1995) (declining to review argument which would not affect sentence), cert, denied, 517 U.S. 1149, 116 S.Ct. 1449, 134 L.Ed.2d 569 and 518 U.S. 1026, 116 S.Ct. 2567, 135 L.Ed.2d *382 1084 (1996). As to Guy’s pro se arguments, the government did not breach the plea agreement, which specified that the sentencing range could be higher than was estimated during plea negotiations, and Guy’s ineffective-assistance claim is not properly raised in this direct criminal appeal. See United States v. Martin, 59 F.3d 767, 771 (8th Cir. 1995).

Upon careful review of the record, see Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we find no other nonfrivolous issues. Accordingly, the judgment is affirmed. We also grant counsel’s motion to withdraw.
