In the Arena / 3rd Washington International
22. f4 With the idea of 23. e5 dxe5 24. f5.
22. ... Qb2?! He took off his gloves and so did I. (22.
... Qg7 23. Rf2 Rce8 24. Rb1 Nb6 25. Qf3 and White has a strong attack).
23. Rf2 Qxa3 24. e5 c4 25. f5!! White has no time to waste with e5-e6.
25. ... cxb3 26. Bb1 The bishop must stay on this diagonal.
26. ... dxe5 27. Qh6 Qe7 Here I spent 15 minutes calculating
White’s options, reaching the one minute mark. Yaroslav had only about a minute as well. The rest of the game was played on the increment.
28. Nh5! Less effective is 28. f6 Nxf6 29. Nf5 gxf5
30. Rxf5 Ne4!! (30. ... Kh8 31. d6 Nxd6 32. Rxf6 e4 33. Rfxd6) 31. Bxe4 f6 32. Rh5 Rc7 33. Rd3 Kf7 when Black keeps the extra material. 28. Ne4 gxf5 29. Rxf5 f6 30. Rf3 Kh8 and the attack seems to have stopped.
28. ... gxh5 29. f6 Nxf6 30. d6! Nxd6 31. Rxf6 e4 32. Rfxd6
Despite the seeming material equality, the black king is way too exposed.
32. ... b2? The following two alternatives fail: 32.
... Rfe8 33. R1d5 Kh8 34. Bxe4; 32. ... Rc7 33. Bxe4 Qxe4 34. Rd8. This keeps Black in the game: 32. ... Rc5 33. Qe3 Qe5 34. Qxb3 Rc1.
33. R6d5 Kh8 At A Glance ⁄2
34. Qf4? After I played this I immediately realized
I had 34. Bxe4 (The proof is 34. Bxe4 Qxe4 35. Qf6+ Kg8 36. Rg5+ Qg6 37. Rxg6+ hxg6 38. Qxb2 and White should be winning for the following reasons, after opening the h- file with g2-g4, the white rook will transfer to the h-file and connect with the queen on h8, or White could just trade a pair of rooks and bring the king to h6!
34. ... Rc4 35. Re5 Qa7+ 36. Kh2 Better is 36. Kh1! f6 37. Rxe4.
36. ... f5?
Black can equalize with 36. ... f6 37. Rxe4 Qb8!.
37. Rxf5 Rxf5 38. Qxf5 Qc7+ 39. Kh1 Qe7 Here he actually flagged, but White is simply winning anyway.
40. Rd7 Rc1+ 41. Kh2 Rc5 41. ... Qxd7 42. Qf8 mate.
42. Qf2! Qe5+ 43. g3 Qf5 44. Qd4+ Qe5 45. Rd8+ Kg7 46. Qd7+ Kh6 47. Qd2+ Kg6 48. Bxe4+ Qxe4 49. Qd6, Black resigned.
Kayden Troff, the current youngest U.S.
GM (although several players in this event may soon claim this distinction), had a very interesting endgame win against FM Kevin Wang in round six.
The last critical moment GM Kayden Troff (2617) FM Kevin Wang (2402) 3rd Annual Washington International (6) 08.11.2014 Notes by Troff.
BLACK TO PLAY It’s been a long game and my opponent
has held on pretty well but this was the last critical moment of the game.
60. ... h3?
After 60 moves he makes his first real mistake. This is a tough position and I thought that he probably couldn’t hold a draw but looking at it afterwards he could have: 60. ... Bd7! 61. b6 Bc8. These moves and (more importantly) the idea behind them were necessary to find. The idea is that, surprisingly, I cannot break through if he sits tight and holds his position. The main line is 62. Kf2 (62. Kg2 Kf6 63. Kh3 Kg5) 62. ... Kf6 (It is important that he brings his king to g5.) 63. Ke3 Kg5 64. Kf3 Ba6 which draws; The knight is uneatable 60. ... Kxd4? 61. f6 Be6 62. b6, and White gets a queen.
61. Kg3 Kf6 No better is 61. ... Bd7 62. b6 Bc8 63.
Kh2 And now Black is in Zugzwang. And after 63. ... Kf6 64. Kxh3 White brings his king up to help the f-pawn promote.
62. Kxh3 Now he can’t stop both of my passed
pawns since my king is no longer tied down to his passed h-pawn.
62. ... Kg5 63. Kg3 Bd7 64. b6 Bc8 65. Kf3 Ba6 66. Ke3 Kf6 67. Kf4 Bb7 68. Nb3 Bc6
Also losing is 68. ... Bc8 69. Nc5 d4 70.
b7 Bxb7 71. Nxb7 d3 72. Nc5 d2 73. Ne4+ Kf7 74. Nxd2.
69. Na5 Ba8 70. b7 Bxb7 71. Nxb7 d4 72. Nc5, Black resigned.
