Nf3 b6 4. g3 Bb7 5. Bg2 Be7 6. O-O O-O 7. Nc3 Ne4 8. Nxe4 { This exchange leads to very drawish positions. 8.Qc2 or 8.Bd2 are slightly more testing lines. } 8... Bxe4 9. Ne1 Bxg2 10. Nxg2 d5 11. cxd5 exd5 12. Bf4 a5 13. Rc1 Na6 14. Qa4 c5 { Checa wastes no time in advancing his queenside majority. } 15. Rfd1 Bf6 16. Be3 { Also possible was } (16. Be5 Bxe5 17. dxe5 Rb8 18. Nf4 d4 { With an interesting position and play for both sides. }) 16... Re8 17. dxc5 bxc5 18. Nf4 d4 19. Bd2 Bg5 20. Qc4 Bxf4 21. Bxf4 Qe7 { White has managed to arrest Black's pawns, and now may begin undermining them with Re1 and e3. } 22. Re1 Qb7 23. b3?! { A slight inaccuracy, as it gives up control of the c3 square. Black now embarks on a maneuver to make use of this new outpost. Better would have been to undermine the central pawn duo with the pawn break 23.e3. } (23. e3 dxe3 24. Bxe3 Qxb2 25. Red1 Qf6 26. a3 Qc6 $10) 23... Nb4 24. a3 Na2 25. Rc2 Nc3 26. Bd2 { This immediate reaction invites the knight to take up a central role via the e4 square. Better would have been to deny the knight this route with the prophylactic move } (26. f3) 26... Ne4 27. Rec1 h5 28. Be1 Ng5 29. h4 Ne6 30. Rd1 Qe4 31. Qd3 Qb7 32. Rc4 Ra6 33. b4?? { An unfortunate blunder that allows Black to achieve a winning position in combinative style. } 33... axb4 34. axb4 Nf4! 35. gxf4 Rg6+ { The threat of mate forces White to jettison the queen. } 36. Qxg6 fxg6 37. bxc5 Qc8 38. Rcxd4 Qg4+ 39. Kh2 Qxh4+ 40. Kg2 Qg4+ 41. Kh2 Rxe2 42. Rd8+ Kh7 43. Rf8 h4 44. Rd3 Rxe1 45. Rdd8 Qg1+ { {#R} 0-1
