Kg1 Rg8 One move too late. Now that wK is closer to shelter, it's better to play 34... f3 35. Qf1 Qg4+ 36. Kh1 fxe4 . 35. Kh1 Rxg7 36. Qf1 Qxc3 37. Bd3 f3 38. Rd1 Ba4?? Black is ruining his position. 38... f4 secures the point. 39. Qxf3 Bg4 40. Qxf4+ Kg8 The R must move, but not off the back rank, so the B is lost. 39. Rb1= White gains a vital tempo to take the f-pawn. 39... Kg8 40. Qxf3 Bc2 41. Qxf5 Black's Q and B remain out of action just long enough for White to grab a perpetual check. 41... Bxb1 42.

Frank escaped another would-be crushing attack after his opponent played one lazy move.

Ne5 Nxe5 10. dxe5 Nd7 11. f4 Nf8 11... b5!? is a more active bid for play. It can't hurt to open the c-file with the wQ there, either. Instead, Black continues to develop slowly enough for White to build up a K-side attack unhindered. 12. b3 Bd7 13. Bb2 Rc8 14. Kh1 Qb6 15. Rac1 Red8 16. e4 Be8 17. f5 Bg5 18. f6 d4 19. h4 19. c5! Qa5 20. Nc4 Qxc5 21. Ba3 secures the nice d6 outpost for the steed. 19... Be3 20. Rce1 Nd7 20... Qa5 21. Nf3 c5 reinforces the d4 pawn and gives the Be8 a diagonal to play on. 21. Nf3 gxf6 22. exf6 Nxf6? An oversight, but Black was lost anyway. 2rrb1k1/ pp3p1p/1qp1pn2/8/2PpP2P/1P2bNP1/PBQ3B1/4RR1K w - - 0 23 22... e5 23. Qe2 Kh8 24. Ng5 Bxg5 25. hxg5 Qc5 26. Bh3 planning Bf5, Qh5 and/or Rh1 with a strong attack. Black's unfortunately placed Bishop hurts his defensive chances. 23. Nxd4? 23. Rxe3 immediately exploits the newly created pin. The wriggling attempt 23... Nh5!? 24. c5 Nxg3+ (else White just plays Nxd4) 25. Kg1 Qa5 26. Bxd4! Nxf1 27. Bxf1 gives the Q a straight shot to g2. White has a dangerous attack. 23... Bxd4= 24. Rxf6 Qa5 White probably hoped for 24... Bxf6?? 25. Bxf6 and a Q check on the g-file finishes matters. 25. Bxd4? Qxe1+ 26. Rf1 Qxg3 27. Bf6 White continues to play for an attack, unable or unwilling to believe that the well has run dry, especially when his position was so promising five moves ago. 27... Rd3 28. Rg1 Kf8 29. Qc1 Qe3 30. Qa3+? A worthless check that just puts the Q out of play. 30... c5 31. Qb2 Rd4? There were better ways to keep up the pressure. 31... Bc6 32. Bg5 Qd4 is the non-sacrificial way to keep the wQ out of the long diagonal. 32. Bg5?? White's 'attack' has been a dismal failure; it was time to admit it, grab some material, and get back in the game. 32. Bxd4 Qxd4 33. Qc1 32... Qg3 33. Qc1 Bc6 34. Bf6 Bxe4! White might as well resign after this move. He can defend the threat of ...Qh3#, but he can't withstand the entrance of a third attacker. 35. Qh6+ Ke8 36. Be5 Qh3+ 37. Bh2 Bxg2+ The finish is ( 37... Bxg2+ ) 38. Rxg2 Rd1+ 39. Rg1 Qf3# 0-1 [Ryan/Fritz 9]

White is very lucky to survive the attack.

1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. e3 c6 6. b4 O-O 7. a4 a6 8. c5 Bg4 9. h3 Bxf3 10. Qxf3 Nbd7 11. Bb2 e5 12. O-O-O? The wrong spot for the King. Black can easily open the position on the Queenside, thanks to White's advanced pawns. 12... e4 13. Qe2 b6 14. g4 bxc5 15. dxc5 15. bxc5 at least limits Black to only one open file. 15... Rb8 16. Na2 16. Qxa6!? Qc7 17. Bb5 Ne5 (17... cxb5 18. Nxb5 gives White play he doesn't deserve) 18. g5 Nfd7 19. Nxd5?! cxd5 20. Qd6 Qxd6 21. cxd6 gets the Queens off for a small material investment, but Black returns the favor: 21... Rxb5! 22. axb5 Rc8+ 23. Kb1 Nd3 and Black has several weak pawns to target. 16... a5 17. Ba3 axb4 18. Bxb4 1r1q1rk1/3n1pbp/2p2np1/2Pp4/PB2p1P1/4P2P/N3QP2/2KR1B1R b - - 0 18 18... Rxb4! I really wanted to criticize this move. Unfortunately, it has one strong, inescapable point: It removes White's best defensive piece. 19. Nxb4 Qa5? It's hard to blame Black for thinking that White had no counterplay. Black could have won by grabbing a pawn and steering the N towards its strongest post, d3. 19... Nxc5 20. Qc2 (20. Nxc6? Qd6 21. Nd4 Rc8 22. Nc2 Nd3+ and White had better give back the exchange (already!) because 23. Kd2 Rxc2+! 24. Kxc2 Qc5+ mates.) 20... Qb6 and White is in a pitiable position. He can't possible stop all the potential invasions on the a-file (... Ra8xa4), b-file (...Rb8) and long diagonal (...Nfd7, releasing the Bishop). His N can't even move away without allowing ...Nb3+ and a 'windmill'. 20. Nxc6 Qxc5+? Black ends up attacking with just the Queen. 20... Qxa4 21. Qa6 Qb3 still offered attacking chances. ...Nxg4 and ...Nxc5 are both in the air. 21. Qc2= Qa3+ 22. Kd2 d4 22... Kh8 23. Nd4 Qb4+ 24. Qc3 Qb8= 23. Bc4? Under no circumstances should the pawn be allowed to live. It single-handedly revitalizes Black's attack. 23. Nxd4 Nd5 24. Nb5 Qb4+ 25. Ke2 leaves Black without a good follow up. 23... d3 24. Qb3 Qd6 25. Bb5? 25. Rc1 Nc5 26. Qa3 25... Nd5?? Winning is 25... Nc5 26. Qc4 (26. Qa2 and now Black does get away with 26... Nd5 27. Qxd5 Qf6! and wK has nowhere to hide) 26... Nxg4! 27. hxg4 Qf6 and White has no good answer to the twin threats of ...Qb2+ and ...Qxf2+. 26. Qxd5! This move hits like a cold shower. 26... Bc3+?? A move borne of (understandable) frustration. If Black had calmed down, he might have found our familiar friend, 26... Qf6! which is still strong enough to keep the result of the game in doubt. 27. Kxc3 Qa3+ 28. Qb3 Qc5+ 29. Kd2 Qd6 30. Qc3 Rc8 31. Ne7+ Qxe7 32. Qxc8+ Kg7 33. Qc3+ 33. Bxd7 33... Ne5 34. Bxd3 exd3 35. f4 1-0 [Ryan/Fritz 9]
