73rd Ukrainian Women’s Chess Championship; Kiev, June 17, 2013
Sicilian Defence B33

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6 8. Na3 b5 9. Nd5 Be7 10. Bxf6 Bxf6 11. c4 b4 12. Nc2 a5 13. g3 0-0 14. h4 Be6 15. b3. For 15. Bh3 Ra7 16. Kf1 Bxd5 17. Qxd5 Qb6 see Abdulla – M. Muzychuk, 10th Women’s European Team Chess Championship, Warsaw 2013. 15. ... g6 16. Bg2 Bg7 17. 0-0 Ra7. Black’s Queen-Rook thematically goes to the Kingside. 18. Qd2 f5 19. exf5 gxf5 20. Rad1 f4! Mariya sacrifices a Pawn for the sake of the initiative. 21. Nxf4. Olga accepts the gift. 21. ... exf4 22. Bxc6 Bg4! 23. Rde1? No doubt the cause of all White’s subsequent troubles. White had to play 23. f3 Bh3 24. Rfe1 since after 24. ... Qb6+ 25. Qf2 Qxc6 26. Qxa7 Qxf3 27. Qf2 fxg3 28. Qxf3 Rxf3 29. Nd4 Rf2 Black’s initiative fully compensates for the sacrificed Exchange, but probably not more. 23. ... Bc3 24. Qd5+ Kh8 25. Rb1 Rg7. Black evidently has a terrific attack. 26. Nd4 Qf6 27. Nf3 Bh3 28. Kh2. Sad, but necessary. 28. ... Bxf1 29. Rxf1 fxg3+ 30. fxg3 Be5 31. Rg1

31. ... Rfg8? A slip by Mariya. Both the “loud” 31. ... Bxg3+! 32. Rxg3 Qf4 33. Ng5 Qxh4+ 34. Kg2 Qf4 and the “silent” 31. ... Rg4! followed by ... Rf8-g8 (as 32. Nxe5?? is refuted by 32. ... Rxh4+! 33. gxh4 Qxh4+ 34. Kg2 Rf2 mate) would have won easily. 32. Nxe5 dxe5 33. Qe4? Olga misses her chance! White could have put up stronger resistance by 33. Qf3. 33. ... Rg4! 34. Qf3 Rxh4+! 35. Kg2. Alternatively 35. gxh4 Qxh4+ 36. Qh3 Qxh3+ 37. Kxh3 Rxg1 simplifies to an easily winning ending. 35. ... Rf4! 0 : 1. For if 36. Qd5 then 36. ... Rf2+ and mate next move.
