| Jul-12-15 | | mel gibson: Great game -
DR4 64 bit agrees with the solution.
It's a perfect example of what happens when you don't castle your King. |

| Jul-12-15 | | diagonalley: rook sacrifice *14* moves before the end!? ... a leap of faith shurely!? ... agree with <An Englishman> ... (double sigh) |
|
| Jul-12-15 | | saturn2: 20 Rxf5 gxf5 21 Bh5+ Kf8 22 Rxf5+
a:if Black interposes a piece he looses it, since it is attacked 3 times and defended only 2 times
b: if 22...Kg8 23 Rf7 and the black Queen gets trouble. |

| Jul-12-15 | | morfishine: I had <20.Rxf5> |
|
| Jul-12-15 | | Al2009: @dzechiel
21.Bh5! was better, and I can show you why.
21...Kf8 22. Rxf5+ Kg8 23. Rf7 Qxf7 (only) 24. Bxf7+ 25. Kxf7 and now 26. Qd1!!
is devastating, and Black is in zugzwang It cannot move pieces any more If 26...h5 27. Qf3+ etc.
I analyzed several variations, White can also move g2-g4 etc. |

|
| Jul-12-15 | | wooden nickel: Material is even <with same-colored knights?!> and Black is already pushing White around by attacking his knight and threatening to win the quali, the problem is he didn't castle yet and is literally pushing White into making this nice rook sac 20.Rxf5!
after 20... gxf5 21.Rxf5 h5

I wasn't sure which move, but the played 22.c5 turns out to be an elaborate choice!
Nice pun "Don't Judge a Rook by its Cover" |

is devastating, and Black is in zugzwang It cannot move pieces any more.In his video comment Gufeld mentions this variation (it also was my 'solution') up to move 25 and says it is not enough, because black gets more than enough compensation for the queen. (Q+2P vs 2R+B)
I also dont understand, why you think it is zugzwang for black. |
|
| Jul-12-15 | | agb2002: The material is identical.
Black threatens fxe4, g5 and Bxf4.
These threats and the position of the black king suggest 20.Rxf5 gxf5 (20... Bxb2 21.Nxd6#) 21.Bh5+ Kf8 22.Rxf5+ Kg8 (22... Nf6 23.Qe8#; 22... Bf6 23.Bxf6 wins decisive material) 23.Rf7 (traps the queen) 23... Qxf7 24.Bxf7+ Kxf7 25.Qa3 winning the pawn on d6 (queen and three pawns vs two rooks and a piece) and a much better position because the black king is still unsafe and the black pieces lack development and coordination. I can't do more today. |

 | | Jimfromprovidence: <JoergWalter> <On youtube there is a video where Gufeld presents this diamond studded game. It is big fun to watch a very temperamentful Gufeld and his management of the english language. Highly recommended> Loved the videos. This guy was a natural born teacher; he was very proud of his own performance as well, as he should have been. I liked the way he described that he was afraid to play 30 c7 because of possible complications from black's ability to castle next move. He felt that his analysis of 30 c7 was not complete enough to go forward with that particular move with confidence. It's interesting because black can still castle after the text 30 Bc4. Here is the position after 30...O-O.

White to play and win. |
|
| Jul-13-15 | | CHESSTTCAMPS: Material is even, but white has several tempos advantage in deployment, with black uncastled and the rooks and light-squared bishop still at home. Black threatens fxe4 and g5 (fwiw), but white is in a great position to sacrifice to further expose the vulnerable king in the middle. 20.Rxf5! Obvious, but requiring some calculation nonetheless. 20... gxf5 21.Rxf5! (Bh5+ Kf8 22.Rxf5+ Kg8 gives king more freedom) h5 (other 22.Bh5(+) wins) 22.Ng5! Qg6 (otherwise 23.Ne6 wins immediately) 23.Bd3 (threatening Rxd5+ and Ne6) Bd4+ 24.Kh1 b5 25.Qc2 Qg8 (otherwise 26.Re5+ is crushing) 26.Ne6 Bb6 27.Rxh5! Rxh5 28.Bg6+ Qf7 29.Bxh5! Qxh5 30.Nxg7+ wins. Not going to try for broader analysis tonight, but this seems to work... |
|
| Jul-13-15 | | CHESSTTCAMPS: Having now seen the game, I still like 22.Ng5. Computer analysis, anyone? |
|
| Jul-13-15 | | devere: A brilliant win by Gufeld! |
|
| Jul-13-15 | | ASchultz: I agree Gufeld's video is well worth a look! His English isn't perfect and that doesn't matter. I found it captivating to follow with analysis running on the side. A reminder everything doesn't have to be perfect for a lot to go well. I think Gufeld definitely has "it." I took a SWAG at Rf5 because aggressive moves are aggressive, but it was instructive to see the how and the way. |
|
| Jul-13-15 | | Al2009: @saturn2
Gufeld was in error in his video, simply because he just statically evaluated the material, without laboring the position, and without realizing that Ra8 and Bc8 are motionless (blocked by Nd7), and any moves of Nd7 causes losses of material (25...Nc5?? 26. Nxc5 and 26. Qh5+ followed by Qxe5 winning a piece) . After 25. Qd1!! Black is quickly lost.
a) 25...h5 26. Qf3+ Kg7 27. Qe3!Rh6 28. Qg5+ Rg6 29. Qe7+ followed by Ng5 and White wins b) 25...Rg8 (the best) 26. Qf3+ Kg7 27. Qg4+ Kh8 28. Qe6! Kh7 29. Nxd6 and again White is winning It took White 13 moves, after 21. Rxf5, to win.
How can you really say that it was the best choice and there were no faster ways to win? Of course Gufeld was just trying to defend his own moves in the game as the best ones, but that is not true! |

| Jul-17-15 | | patzer2: Here's my look at this game and the Sunday July 12, 2015 puzzle (20. ?) with the chessgames.com Opening Explorer and Deep Fritz 14: <1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Nd5 Nxd5 8. exd5 Nb8 9. c4 a6> Here I prefer the popular move 9... Be7 as in Wei Yi vs Zhao Jun, 2010 or M Lokander vs J L Hammer, 2015. <10. Nc3 Nd7> Here I prefer 10... Be7 as in
Svidler vs A Timofeev, 2004 or Do Duc Minh vs W So, 2004. <11. Be2 g6> Here <RV>'s Rybka suggestion 11...Be7 = is my preference and also the first choice of Deep Fritz 14. <12. O-O Bg7?> This natural move is premature. Better is the Fritz suggestion 12... f5 when play might continue 13. Qa4 Rb8 14. Be3 f4 15. Bd2 Be7 16. Ne4 O-O = (0.00 @ 21 depth, Deep Fritz 14). <13. Ne4 Qe7 14. Qa4 f5 15. Bg5 Qf8 16. f4 h6 17. Bh4 exf4 18. Rxf4 Be5
19. Raf1 Qg7?> This loses to White's brilliant reply. Black can put up
more resistance with 19... Bxf4 20. Rxf4 Kf7 but after 21. Qb4 a5 22. Nxd6+
Kg8 23. Qa3 Rh7 24. Rf3 g5 25. Bf2 Ne5 26. Re3 Re7 27. Nxc8 Rxc8 28. d6 Re6 29. c5 Qf6 30. Qxa5  to  (+1.81 @ 20 depth, Deep Fritz 14) White has a near winning advantage. <20. Rxf5!!> This solves last Sunday's puzzle. <20...gxf5 21. Rxf5!> Though it
might win with difficulty, much weaker is the tempting 21. Bh5+ Kf8 22. Rxf5+ Kg8 when play might continue 23. Bf7+ Kh7 24. Ng5+ hxg5 25. Qc2 Bxh2+ 26. Kxh2 Kh6 27. Qf2 Ne5 28. Rf6+ Qxf6 29.

Bd3!> This is another critical winning follow up. <26...Qg7 27. c6!> This is yet another critical follow up needed to insure the win. <27... bxc6> If 27... Nc5, then play could continue 28. Rxe5+ Be6 29. Rxe6+ Nxe6 30. Qxe6+ Kf8 31. Bf6 Qg6 32. Be7+ Ke8 33. Bxg6#. <28. dxc6 Nc5 29. Rxe5+ Ne6 30. Bc4> This wins but stronger is 30. Rxe6+! Bxe6 31. Qxe6+ Kf8 32. Be3 Qe7 33. Qf5+ Ke8 34. Bc5 Qf7 35. Qe5+ Kd8 36. Bb6+ Kc8 37. Bf5+ Qxf5 38. Qc7#. <30... Qa7+ 31. Be3 Qh7 32. Rxe6+ Bxe6 33. Qxe6+ Qe7 34. Qg6+> Black resigns in lieu of 34...Kd8 35. Bb6+ Kc8
36. Be6+ Kb8 37. Qg3+ Qd6 38. Qxd6#.
P.S.: Got 20. Rxf5!! for my Sunday puzzle solution, but after 20...gxf5 I missed 21. Rxf5! and lost my way trying to find a win with 21. Bh5+. |
