1. Nf3f5 2. c4Nf6 3. g3g6 4. Bg2Bg7 5. Nc3d6 6. d3O-O 7. Rb1e5 8. O-ONa6I didn't want to allow myself to become too reactive to White's queenside plans. But with benefit of hindsight, it might have been better to play something like ...a5 instead.
9. Qc2c6 10. b4Nc7 11. a4Rb8 12. b5Bd7 Maybe 12... cxb5 would have been better.
13. b6axb6 14. Rxb6Ne6 15. a5Qc7 16. Qb1White's c3 knight becomes loose, and I began keeping an eye out for an exploit based on my g7 bishop.
16... Nc5 17. Ba3e4I was trying to counteract White's queenside expansion by playing in the center.
18. Ne1exd3 19. exd3Be6 20. Nf3Nfd7 Trying to capitalize on the loose knight. It ends up netting a pawn.
21. d4Na6 22. d5Bf7 23. Rb3Nac5 24. Bxc5Nxc5 25. Ra3Bxc3 26. Rxc3Qxa5 27. Rc2cxd5?First step on the road to losing control of d5.Now 27... Qd8 looks better to me. My queen is out of play on a5.
28. Ng5dxc4? Second step, giving up my own light-squared bishop.
