12. Nd5 Nxd5 A deservedly more popular move is 12... exd5!? though after 13. exd5 white threatens to recover the piece with Nf5. 13... Kf8 14. Nf5 Bd8 15. Nxg7 Kxg7 16. Qg3 (threatening 17.Bxf6 Kxf6 18.Qg5#) 16... Nh5 (16... Rg8 17. Bxf6+ Kf8 18. Re8+ Kxe8 19. Qxg8+ Nf8 20. Re1+ Kd7 21. Bf5+ Ne6 22. Bxe6+ fxe6 23. Qxe6#) 17. Qg4 Bxg5 18. Qxg5+ Kf8 19. Qxh5 Nc5 is the only defense, taking away the possibilities of Qh6+. Interestingly, Fritz thinks this position is relatively even, despite White's piece deficit.(19... h6) 20. Qh6+ Kg8 21. Re3 13. exd5 Bxd5 Best might be 13... Bxg5 14. fxg5 but gives up the e5-square and allows Black to defned with ...Ne5 followed by . ..Bxd5.(14. Rxe6+ is more in the spirit of the position: 14... fxe6 15. Nxe6 Qa5 16. Qh5+ g6 17. Bxg6+ Ke7) 14... Ne5 followed by 15... Bxd5 14. Qxd5 exd5 15. Rxe7+ Kf8 16. Bf5










16... h6 Multiple picturesque mates are threatened after 16... Rd8 17. Be6 f6 18. Rf7+ Ke8 19. Rxg7 20. Bf7+ Kf8 (20... Ke7 21. Bg6+ Kf8 22. Ne6#) 21. Ne6+ Ke7 22. Bg6+ Kxe6 23. f5+ Ke5 24. Re7# 17. Rxd7 Qxd7 18. Bxd7 hxg5 19. h3 Better was traps the rook. 19. fxg5 since 19... Rxh2?? 20. Bh3 19... gxf4 Despite the relative material equality, rook and two pawns for bishop and knight, White is winning here. Let's compare the positions: Black has many weak pawns, while White's are all healthy. White's minor pieces are active: in particular the knight has an excellent square at d4, while Black's rooks cannot use the half-open e- and c-files. White's king is safe and well-place, but Black's blocks his h8-rook and is vulnerable to harassing checks from the knight. 20. Bc6 Ra7 21. Bxd5 g6 22. Bf3 Rd7 23. Nc6 Kg7 24. Nb4 a5 25. Nd3 g5 26.

Black resigned. Medina's advice to young girls who want to improve at chess: "Always study, play as much as you can, and don't let losing get you down." 1-0 [Vicary E.]
