1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. f3 e5 7. Nb3 Be6 8. Be3 Nbd7 9. Qd2 b5 10. O-O-O Rc8 11. g4 Nb6 12. g5 Nh5 {This moves the knight farther away from the queenside, but now Black's plan shifts to targeting White's weak kingside pawns. For now, f3-f4 is also prevented, and the knight may someday itself find a home on f4.} 13. Kb1 Be7 14. Rg1 O-O 15. Qf2 Nc4 16. Bxc4 Rxc4 17. Nd5 Bxd5 18. exd5 {18. Rxd5 f5 19. exf6 Nxf6 20. Qg2! as in GM Deepan Chakkravarthy - GM Dao Thien Hai, Cebu 2007, should be about equal.} Nf4 19. Bxf4 Rxf4 {Black appears a little better.} 20. Qg3 Qc8 {Perhaps an inaccuracy, as now Na5-c6 is possible.} 21. Rd3 Qf5 {I originally planned for 21... Qf5 22. Na5 h6 and if 23. Nc6 (23. gxh6? g6) then 23... Bxg5, but that fails to 24. Ne7+!. So it seemed 21... Bd8 was called for. But then I realized 21... Qf5 22. Na5 Re8! 23. Nc6 Bf8 is perfectly satisfactory. The knight is pretty, but it is perhaps the only good thing about White's position, and Black has thematic play with ...g6, ...Bg7, ...Rf8, and ...f6.} 22. Nd2 f6 {Now the endgame after 23. g6 Qxg6 24. Qxg6 hxg6 25. Rxg6 Kf7 and ...Rh8 is very nice for Black.} 23. gxf6 Qxf6 24. Ne4 Qh6 25. Ra3 {The rook is misplaced here as White has no serious threat.} g6 {Before doing anything, Black has to fix the weakness of the critical square g7. Now the Black queen is available for use.} 26. Rxa6 {Simply a blunder.} Rxf3 27. Qg2 Qxh2 {White resigned here. The end would have been: 28. a3 Rf1+! 29. Qxf1 (29. Ka2 Qxg1) 29... Rxf1+ 30. Rxf1 Qg2 31. Re1 Bh4 32. Re3 Qg1+.} 0-1
