Be3 {The idea is to harass the queenside holes, particularly b6 with the bishop, knight, and queen. } Bd7 10. Na4 Ra6 {I calculated that the rook could come here to defend b6. However, I was okay with this because it takes away the last square from the knight. If I were to force a trade of the knight for the bishop, getting a knight to e6 would be deadly.} 11. Nc3 cxd5 12. cxd5 b5 13. a4 {The only move that maintains my positional advantage and doesn't let black expand on the queenside.} b4 14. Nb5 Ra8 15. Rc1 Na6 16. Qb3 Qb8 17. Nfd4 Nc5 18. Rxc5 dxc5 19.
