| Dec-16-09 | | WhiteRook48: what if black declines the 15 Rxe6 sac? |
|
| Dec-16-09 | | TheChessGuy: The person who mentioned Paul Keres earlier was right on target. Paul Felix Schmidt was a fellow Estonian who likely influenced the aggressive, tactical play that the pre- and early-Soviet Keres is known for. |
|
| Dec-16-09 | | psmith: <WhiteRook48>: what do you have in mind instead of 15...Kxe6? Here is what I came up with using Fritz 5.32:
(a) 15... Nf6 16. Rde1 Bd6 (16... Rhe8
17. Nh4 Nd5 18. Bg6+ Kg8 19. Bxe8 Rxe8 20. Nf5  ) 17. Bc4 Nd5 18. Qd3
(b)15... b5 (to stop Bc4)16. Bg6+ Kxe6 17. Re1+ Kf6 18. Qd3 Qf4 19. Re4
(c) 15... Bf6 16. Bc4 Kf8 17. Rde1
g6 (17... b5 18. Qe3 Qd8 19. Qa3+ c5 20. Bxb5 a6 21. Bxd7 Qxd7 22. Qxc5+ ) 18. Qe3 Any improvements? |

 | | benveniste: It looks like Black's key error was 18. ... ♔g6. 18. ... ♗c8 seems to equalize. |
|
Dec-16-09
 | | Jimfromprovidence: <benveniste>
Rybka freeware also likes 18...Bc8, because if prevents the continuation 19 d5+ Kg6 20 Qd3+, because black now has 20...Bf5.
click for larger viewIt prefers the continuation 18...Bc8 19 Ne5 h5 and sees an even match at that point.

|
| Dec-16-09 | | psmith: The continuation 18...Bc8 19. Ne5 h5 is one of those computer defenses that a human is unlikely to even take account of. 18...Bc8 undevelops and blocks off Black's Rook, and 19...h5 seems to weaken Black's King position. But actually the first move provides the defense Bf5 and the second prevents 20. Qf3+ Bf5 21. g4 which is strong against other 19th moves. But, but, but: the evaluation "even match" for a position in which White is down a piece and a Rook while Black's King is exposed seems bizarre, without further analysis. Maybe it all ends in perpetual. Who knows. |
|
Dec-16-09
 | | Phony Benoni: <psmith> What "even match" probably means is that White sacrifices all his material, but Black runs out of time calculating defenses and the game has to be declared a draw. |

| Jan-22-23 | | Brenin: Embarras de richesses! My choice was 24 Qf4, threatening 25 Qh4+, e.g. 24 ... Qxf5 25 Nd7+ Nxd7 (25 ... Kg6 26 Rg1+ and 27 Bd3) 26 Re6+ Kf7 27 Qxf5+ Ke8 28 Qg5 Nf6 29 Rxe7+ Kxe7 30 Qxg7+ and 31 Qxf6. But there are plenty of other moves, such as 24 Rg1, which look just as good. |
|
| Jan-22-23 | | Mayankk: The poor Black King has been chased to the centre and all the White pieces are circling around, waiting to give the killer blow. My line was 24 Ng6 Nxg6 25 fxg6+ Kxg6 26 Bf7+ Kh6 27 Re6+ Bf6 28 Qf4+ Kh7 29 Qf5+ and 30 Qg6# If 24 Ng6 Bb4, I may have diverged with 25 c3. Now White will likely recover one piece and still keep the initiative. But no way as efficient as 25 Re6+. |
|
| Jan-22-23 | | mel gibson: Almost any move wins.
I chose 24. Nxc6 which wasn't the best but still won.Stockfish 15 says:

| Jan-22-23 | | King.Arthur.Brazil: I figured the line: 24. Nd7+ Nxd7 25. Re6+ Kg5 26. Rg6+ Kh4 27. Qg3#. or 25... Kf7 26. Rh6+ Kf8 27. Rxh8#. The longer way is 25...Ke8 27. Rxh8+ Nf8 28. Be6 Qb7 29. Qxh5+ Kd8 30. Qf7 Rc8 31. Rxf8+ Bxf8 32. Qxf8+ Kc7 33. Bxc8 Qxc8 34. Qxg7+ Kb8 35. Qe5+ Kb7 36. Qe7+ Kb8 37. f6! and win. The other answer is 24. Nf7+ Qxd7 25. Re6+ Nxe6 26. fxe6+ Kg6 27. Qf7+ Kg5 28. exd7 seems that White can win. Not 25... Kg5 26. h4+ Kxh4 27. Qg3#. The remain move is 25... Kf7 26. Rh6+ Ke8 27. Rxh8, similar to previous ones, where Be6 and Qxh5+ must follow. But I'm not sure if the King would follow this line, in a real game; but don't call <Brenin>...lgs. In a game where isn't said 'insane', I'd follow with 24. Ng6, for example: 24... Qxf5 25. Qxf5+ Kxf5 26. Nxh8 Bh4 27. Nf7 Bxf2 or 24... Nxg6 25. fxg6+ Kxg6 26. Bd3+ Kh6 27. Rxe7 with strong attack. Time to check it out. |
|
| Jan-22-23 | | Mayankk: If 24 Ng6 counts as an insane move, while the attack actually started 10 moves earlier via the Knight-Rook sacs - 14 Nxf7 Kxf7 15 Rxe6 Kxe6, then what sort of a difficulty level will 14 White to move be ? Or is it that 14 Nxf7 and 15 Rxe6 were speculative sacs and White had only locked in the win at the 24th move ? |
|
| Jan-22-23 | | Refused: My first instinct was to play 24.Be6, which is also winning. The Bishop is obviously untouchable as
24...Nxe6 25.fxe6+ Kxe6 26.Qf7+ is dead.
and after something like 24...Qc7 25.Qg3 looked good. |
|
| Jan-22-23 | | nalinw: The engine here - which I have little faith in - says that things are equal after the sacs - so Black has not played the best defence |

Black threatens Qxf5.

A) 24... Qxf5 25.Nd7+
A.1) 25... Nxd7 26.Re6+ Kf7 27.Qxf5+ Ke8 28.Qg5 wins. A.2) 25... Kg6 26.Bd3 Qxd3 27.cxd3 Nxd7 (27... Bg5 28.Ne5+ Kh6 29.Nf7+ wins) 28.Rxe7 wins decisive material. B) 24... h4 25.Ng4#.
C) 24... g5 25.fxg6+ Kg7 26.Qf7+ Kh6 27.g7 wins. D) 24... Nh7 25.Nd7+ Qxd7 26.Qe5+ Kg5 27.Qxg7+
D.1) 27... Kh4 28.Qg3#.
D.2) 27... Kf4 28.Qg3+ Kxf5 29.Qh3+ and 30.Qxd7 wins decisive material. D.3) 27... Kxf5 28.Bd3+ Kf4 29.Qg3#.
E) 24... Nd7 25.Nxd7+ as in D.
F) 24... Bd6 25.Ng4+ hxg4 26.Qxd6+
F.1) 26... Kxf5 27.Bd3+ Kg5 28.Qe7+ Kf4 (28... Kh6 29.Qh4#; 28... Kh5 29.Re5+ and mate in two) 29.Qe5+ Kf3 30.Qg3#. F.2) 26... Kg5 27.Qe7+ Kh5 (27... Kxf5 28.Bd3+ transposes to F.1) 28.Bf7+ g6 (28... Kh6 29.Qh4#) 29.fxg6 Kh6 (due to g7+) 30.g7 Kxg7 (30... Rh7 31.Qf6+ Ng6 32.Qxg6#) 31.Be8+ Kh6 (31... Kg8 32.Qf7#) 32.Qf6+ Kh7 33.Re7+ Kg8 34.Qf7#. F.3) 26... Ne6 27.Rxe6+ looks winning.
G) 24... b5 25.Qh4+
G.1) 25... Kxf5 26.Qxe7 recovers material while keeping the attack. G.2) 25... g5 26.fxg6+ as above. |

Rxh8#.> I also figured 24 Nd7+ is a win, but the continuation is 24 .. Qxd7 25 Re6+ Nxe6 26 fxe6+. Then: 26 ... Kg5 27 Qe3+ Kg4 28. h3+ Kf5 (or 28 ... Kh4 29 Qg3#) 29. Bd3+ Kf6 30. Qe5# 26 ...

28 ... Bd8 29. Bd3 Kg5 30. Qg6+ Kf4 31. Qf5# (a similar line follows after 28 ... Bh4), or 28 ... Bg5 29. Bd3 and 30. Qg6#
28 ... Kg5 29. Qxe7+ -- I won't give all the lines, but White now has Q and B for 2 rooks and Black's King is out in the open and getting mated. And if that isn't enough, White has the d7 pawn. |
