Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. f3 e5 7. Nb3 Be6 8. Be3 h5 9. Bd3?! { A rare move, and not one I understand. The bishop interferes with ideas of Nc3-d5, and even facilitates a quick ... d6-d5 from Black, as in this game. } 9... Be7 10. Qe2 b5 11. Qf2 Nbd7 12. Rd1 b4 13. Ne2 a5 14. Ra1? { If White wants to play positional, slow maneuvers, she might want to look for alternatives to the Open Sicilian! } 14... a4 15. Nd2 d5! { As promised! } 16. exd5 Nxd5 17. Bb5 Nxe3 18. Qxe3 O-O 19. Bxd7 Bxd7 { Trading off two pairs of minor pieces should have helped White weather the storm, but now it's two bishops against two knights in a wide open center. Furthermore, Black's four-versus-three kingside pawn advantage looks highly mobile, while White's three-versus-two on the queenside is frozen. } 20. Ne4 Qc7 21. c3 f5 22. Nf2 Bc5 23. Qd2 bxc3 24. Qxc3 Qb6 25. O-O Bb5 26. Qe1 Qa6 { The bishop pair has shown its power, and now it is time to pick up some material and get some rest before tomorrow's games. } 27. Nc3 Bxf1 28. Qxf1 Qxf1+ 29. Rxf1 Rfb8 30. Nd1 a3 31. b3 Rxb3! { Flashy! And accurate! } 32. axb3 a2 33. Nc3 a1=Q 34. Rxa1 Rxa1+ 35. Nb1 Rxb1# { 0-1 Black wins. } 0-1
