Crashdown

侯逸凡 (Hóu Yìfán) – Eduardo Patricio Iturrizaga Bonelli
2nd Chess Festival Eighth Centenary 2019 of Salamanca University; time control: 40 minutes plus 5 seconds per move; Salamanca, November 30, 2019
Caro-Kann Defence B10

1. e4 c6 2. Nf3 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Qe2 Nxe4 (5. ... Nbd7?? 6. Nd6 mate, Keres – Arlamowski, Szczawno Zdrój 1950) 6. Qxe4 Qd5 7. Qh4 Qe6+ 8. Be2 Qg4 9. Qg3 Qxg3 10. hxg3 g6 11. a4!? An interesting strategic novelty which will provide White with a lasting initiative, though in the end 侯逸凡 (Hóu Yìfán) won’t achieve more than a drawish endgame, probably due to some omissions along the way. Proof theory gave 11. d4 Bg7 12. Bh6 Bf6 13. Ne5 Be6 14. 0-0-0 Nd7 15. f4 Rg8 16. g4 Rd8 17. c4 Bxe5 18. fxe5 Nb6 19. b3 g5 20. Kc2 f6 21. exf6 exf6 22. Kc3 Kf7 23. Rdf1 Rg6 24. Bd3 Bxg4 25.

Bg7 12. a5 Bf5 13. c3 e5 (13. ... Nd7 14. d4 0-0 15. 0-0 Rfd8 16. Re1⩲) 14. d3. After 14. d4!? exd4 15. Nxd4 Bxd4 16. cxd4 0-0 17. g4 Be6 “Two Bishops and the better King gives White the upper hand”, says Grandmaster Vasif Durarbayli. 14. ... Nd7 15. Be3 0-0 16. Nd2 Nf6 17. Nc4 (17. f3⩲) 17. ...

57. Rf1+. A pretty drawing variation is 57. b7! Na5 58. Rd6+ Ke7 59. Ra6 Kxd7 60. Rxa5 Rxa5 stalemate. 57. ... Ke7 58. b7?? Crashdown. 58. Kc7 should still be enough for White to draw the game. 58. ... Kxd7 59. Rd1+ Nd6 0 : 1.
