| Oct-25-09 | | Bleepbloop1: although i had seen 0-0 and 0-0-0! as potential solutions, I was intrigued by 12.Bb5?, then I realized black had qe6+! 13. kf1?! cxb2!! 14.rad1 Qxd1+ 15.Nxd1 b1=Q :D however, 13.kd1!? seems a bit stronger for white, probably also winning. Very interesting position! |
|
| Oct-25-09 | | gofer: Well, I have looked at a few things, but nothing seems quite as forcing as Bxf7+ and since getting through most of the typing of this post I realise that really this was quite an easy find... ...probably easier than last Friday's MOTD! 12 Bxf7+ Kxf7
13 Qf4+ ...
13 ... Nf6 14 Ne5+ winning the queen
13 ... Kg8 14 Qc4+ winning the queen and then mating
13 ... Kg6 14 Nh4+ Kh5 15 g4#
So that leaves just two possible moves, both put black in deep trouble. 13 ... Ke6
13 ... Ke8
The white bishop and queen are acting as noose round the black king's neck... ...time to kick away the chair he's standing on... 14 O-O-O!
This is much more active and threatening than O-O which does free up e1 for one of the rooks, but if white plays O-O-O then Rhe1+ is coming and there is already a rook on d1 further tightening the noose! Black can play cxb2+, but white just plays Kb1 and now uses the pawn as a defense! If Black delays playing cxb2+ until later then actually Kxb2 followed by Ka1 may be more appropriate. If Black plays c2 then Rhe1+ is now horrible for black... So the only real question is what defenses has black got??? There are lots of permutations and all of them lose a huge amount of material, so I think black resigns... I have no inclination to look at this in more detail, right now. I hope I haven't missed a really good defense! Time to check... |

| Oct-25-09 | | David2009: <johnlspouge: More Mom-and-Pop evaluations by Toga> Thanks for these a good refutation of Qg6+. Crafty plays 18...Be6 instead of 18...Kg6 and matches Toga (ply 14/54) move for move up till move 25: thus 12.<Bxf7+> Kxf7 13.Qf4+ Ke8 14.0-0-0 cxb2+ 15.Kxb2 Qb6+
16.Ka1 Nf6 17.Rhe1+ Kf7 18.Qc4+ Be6 19.Rxe6 Qxe6 20.Ne5+ Ke7 21.Qxc5+ Ke8 22.Qb5+ Nd7 23.Rxd7 Qxe5+ 24.Qxe5+ Kxd7 25.Qb5+ Ke6 26 Qb3+ Ke5!? (Kd6 - Toga) 
click for larger viewSo far I have played Toga's moves. Now I am on my own: 27 f4+ Kd6 28 Qxb7 Re8 29 Qxa7 Re4 30 g3 h6 31 Bd8 Re1+ 32 Kb2 Re2+
33 Kc3 Re1 34 Kd2 Rh1 35 Qd4+ wins the exchange and another pawn 1-0 (adjudication). 
click for larger viewWikipedia has an article on Crafty. The on-line endgame trainer I use is a cut-down version (no castling or en passant captures) and is rapid-play so is weaker than the full version. [Similarly, Toga 14/54 is weaker than full Toga.] The endgame trainer is very quick, free to use, easy to set positions up in and fun to play against. My current playing strength is around 1700 so Crafty must be at least 300 - 400 better. Creating a link in a 'White to play and win' game is very quick, because one can cut-and-paste the FEN position from the Chessgames.com game. You can also try your luck at old chestnuts (like winning with K+Q against K+R). |

| Oct-25-09 | | gofer: Now I would like to say that I saw the following...
12 Bxf7+ Kxf7
13 Qf4+ Ke8
14 O-O-O cxb2
15 Kxb2 Qb6+
16.Ka1 Nf6
17.Rhe1+ Kf7
18.Qc4+ Be6
19.Rxe6 Qxe6
20.Ne5+ Ke7
21.Qxc5+ Ke8
22.Qb5+ Nd7
23.Rxd7 Qxe5+
24.Qxe5+
At which point a "pro" would have turned the advantage into a win. But I would be lieing. But its nice to see that I wasn't completely "insane". Or at the very least, I am not the only one in the "looney bin"... |

My analysis was done with Fritz ... its clearly indicated as well. " - Fritz 11." (I never intended to anyone think that I did that in my haed.) I GUESSED that 12.0-0-0 was the answer. However, I was NOT 100% sure it would work. This was the main reason that I quickly analyzed the game. Its an amazing game, by the way. Thanks to the CG staff for bringing it to our attention. |

| Oct-25-09 | | MaxxLange: <Its an amazing game, by the way. Thanks to the CG staff for bringing it to our attention.> plus one
what a beautiful move, 12 0-0-0!!, giving up the Queen, with the theme of VACATION of the e1 square, threatening the deadly Re1+ |
|
| Oct-25-09 | | Athamas: I'm not sure of anybody that could do all those variations without a board... I usually decide on a select few moves in my head and move them on my board at home to make sure it's correct and keep moving if I don't see anything decisive initially as it's a puzzle. |
|
| Oct-27-09 | | patzer2: In going back over last Sunday's puzzle (12. ?), the revelation by <johnlspouge> that there are not one but two possible solutions in 12.0-0-0!! or 12. Bxf7+!! continues to amaze me. Even more stunning is the strong possibility that Taimanov move is inferior to 12. Bxf7+!!, based on Toga analysis approaching "best play." Of couse a strong move is only as good as a player's ability to calculate the winning follow-up. In this case, I think 12. 0-0-0!! is the best practical OTB move, while 12. Bxf7+!! might be the best choice in a correspondence or computer assisted match. |
|
| Oct-28-09 | | patzer2: After several days of playing it out against Fritz, I've come to the conclusion 12. Bxf7+!! is better. Here's some analysis based on an over night run and a lot of follow-up move-by-move with Fritz: 12. Bxf7+!! Kxf7 13. Qf4+ Ke8 (13... Kg6 14. Nh4+ Kh5 15. g4; 13... Ke6 14. O-O-O  ; 13... Nf6 14. Ne5+ ; 13... Kg8 14. Qc4+ Qd5 15. Qxd5#) 14. O-O-O cxb2+ 15. Kxb2 Nf6!? 16. Rhe1+ Be7 17. Rd6 Qb5+ 18. Ka1 Rf8 19. Bxf6! gxf6 (19... Rf7 20. Ng5 gxf6 21. Nxf7 Kxf7 22. Rxe7+ Kxe7 23. Qxf6+ Ke8 24. Rd8#) 20. Rxf6 Rxf6 (20... Rg8 21. Rf7 Qd7 22. Ng5 Kd8 23. Rfxe7 Qxe7 24. Rxe7 Kxe7 25. Qe5+ ) 21. Qxf6 Qd7 22. Qh8+ Kf7 23. Ne5+ . |

| Dec-07-09 | | Lovuschka: After considering all analyses here, we can come to this conclusion:
12.Bxf7+ was the best move, winning the game in the attack against the black king.
12.O-O-O was good but could lead to a difficult endgame after the best black defense. Also it seems that 12.Se5? Sxe5!! 13.Bb5 Bd7 14.Bxc6 Bxc6 leads to a game where black has good chances for a draw - if not more. Now the "wrong" player sacrificed the queen... The queen sacrifice of this game first appeared in a simultan game by H. Müller 1934. Black took the queen there and after 12...Qxa4 13.Rhe1+ Be7 14.Rxe7+ Kf8 15.Rxf7+ Kg8 16.Rfxd7+ Qxc4 17.Rd8+ Ke7 18.Se5+ Ke6 19.Sxc4 white was a piece up. Jakov Neistadt says in his book about queen sacrifices, Taimanov later wrote that he found the combination in his game, i.e. he didn't know the predecessor. |

| Feb-07-11 | | mastermind7994: Interesting game..not sure why I haven't heard of this game before. |
|
| Apr-07-11 | | Llawdogg: Wow! 12 0-0-0!! was fantastic. Was the ghost of Paul Morphy visiting Mark Taimanov 100 years after his heyday? Brilliant game! |

| Feb-07-14 | | Mudphudder: Never seen such an impressive Taimanov game before. |

 | | Honza Cervenka: Well, even back in 1960 this was a known opening theory, or better said "opening trap" known at least from 1934, when it occurred in then widely published miniature H Mueller vs Sauke, 1934. Since that time it had maybe dozens of victims including some grandmasters, and some of them went down in a bit different path like Bogdan Sliwa in Sajtar vs Sliwa, 1947. Main culprit of usual black disasters in this line seems to be 8...d4. Instead of that it is better to insert 8...b5! 9.Qxb5 Rb8 as it was demonstrated by Karpov in Miles vs Karpov, 1990. |
|

| | Honza Cervenka: And if you would like to know what can happen if black retakes on f6 by Pawn instead of 10...Qxf6, then look at Pachman vs F Kuijpers, 1964 |
