| Jan-25-12 | | polarx: Saw that 18.Bf6 was the move if there was one but completely overlooked the Bf5 response. So back to patzerland! |
 |
| Jan-25-12 | | polarx: And I am with CG.com and Phony Benoni on why "spoilers" are necessary. |
|
| Jan-25-12 | | AlphaMale: <Sick> is the new <bad>. So describing this game as sick is a term of endearment. |
|
| Jan-25-12 | | moodini: I got it! Too easy. Bf6 and mate is unavoidable. Let me broadcast my brilliance right away. No need to read the posts from any mere mortals. Spoiler? What spoiler? D'oh!
(By the way I confess that I didn't see the Bf5 defence) |
|
| Jan-25-12 | | CHESSTTCAMPS: In this opposite-colored bishop middle-game, white has established dominance on the king-side, while black has done the same on the queen-side. This leaves the black king virtually undefended, and white's lifted rook is ready to join the final attack. The logical target is g7, the square that can't be defended by the DSB. Therefore, my first and only candidate, 18.Bf6!! (credit for "!!" only if you have seen the best defense!) leaves no viable defense: A) 18... gxf6 19.Rg3+ Bg4 20.Rxg4+ Kh8 21.Qf6#
B) 18... Rfc8 19.Qg5 Kf8 20.Qxg7+ Ke8 21.Rxe6+! Kd7 (fxe6 22.Qe7#) 22.Qxf7# C) 18... h6 19.Rg3 Rfc8 (g6 20.Qxh6) 20.Rxg7+ Kf8 21.Rg8+! Kxg8 22.Qxh6 forces mate. D) 18... Rb4! 19.Rg3!! (Qg5?? Rg4! turns the tables) Rfc8 20.Rxg7+ Kf8 21.Qxh7 (not 21.Rg8+?? Kxg8 22.Qh6 Rg4) Ke8 (otherwise 22.Qh8#) 22.Re1! (Bc3 also wins cleanly) Kd7 23.Rxf7+ Bxf7 24.Qxf7+ Kc6 25.Re6+ Kb5 26.Qd7+ Kc4 27.b3+ Rxb3 28.cxb3+ Kb4 29.Qxc8 1-0 (R+Q+B vs Q) D.1) 19... Rxh4 20.Rxg7+ Kh8 21.Rg6#
Good Wednesday puzzle - time for review... |

 | | James D Flynn: I gave up om this after seeing that 18.Bf6 could be answered by Bf5. I then started thinking about forcing the black Q to the B file and winning the R on b8, e.g 19.Qg3 Bg6 20.Ra3 but the black Q doesn't have to go to the B file she has Qd2. |
|
| Jan-25-12 | | CHESSTTCAMPS: Bummed out that I failed to consider 18... Bf5! that seems to have been found by everybody and his/her brother and 3-year-old child... |
|

 | | beenthere240: The point is that some combinations that begin with a quiet (nonforcing) move may have an unexpected refutation. In this game - which was blitz! -- finding ...Bf5 isn't easy, especially when black could hope that the mighty Alekhine has blundered! |

 | | kevin86: No immediate dangers,but black's forces are far from his king. The key move is to force open the pawn structure. If black captures the bishop or advances the pawn,he is lost. If he does neither,the bishop just just takes the pawn himself. |
|
| Jan-25-12 | | gofer: <Phony>: I don't think this is a spoiler... "Usually these positions present the lure of potential sacrifices which are unsound." I would normally expect a spoiler to throw up a "winning" move that leads to a loss. <Bf6> is not unsound. It just doesn't win. Not really a spoiler then... ...that said, I hope we get a real <spoiler> tomorrow! Just to shut me up... |

 | | Phony Benoni: <gofer> Well, they did say <usually>. The greatest spoiler I remember came from this position in Lepeshkin vs Alekseev, 1955:

There are seven pages of kibitzing, and I would advise you to start at the beginning to get the full effect of the analysis and the impact of the revelation. |

| | benveniste: chessgames, was this a spoiler or merely a cooked puzzle? I don't see anything better the  f6. |
|
| Jan-25-12 | | The Rocket: Its an incorrect puzzle since bf6 is not the best move because of bf5. |
|
| Jan-25-12 | | The Rocket: But I was tricked as well hehe. o well it doesn't lose |
|
Jan-25-12
 | | chrisowen: I feel myself plumping for bf6 if the bishop in no time like the future ar bf5 et tu brute holds pinafore in dress it tracking really it troubadour in cognizant it going again tame it snuff said lost it chin up end. |
|
| Jan-25-12 | | erniecohen: Just a bad, bad POTD. There's nothing cloise to a win for white. Would it really be that hard to just run the key move through an engine before posting? It takes like a second. |
|
| Jan-25-12 | | poachedeggs: The question is, why would Black play 17...Rab8 after the white Q positions herself on the H file? Pawn grubbing gets the better of even the best... |

 | | Once: This is what CG says about spoilers:
<"We occasionally show a puzzle that we call a spoiler. These are positions where there is no move that clearly wins the game, but instead a variety of solid moves which are all playable. Usually these positions present the lure potential sacrifices which are unsound. You are expected to recognize the unsoundness of the tempting sacrifices and instead conclude that the best move is one of the "quiet" moves, or an obvious move like capturing a pawn."> Does that really describe today's POTD? I can't see how it does. We haven't got a tempting sacrifice and there isn't a better "quiet" move. Later on, the same "about our puzzles" text says this about how to find the answer: <"The move played in the actual game is almost always the solution, although every now and then the correct move was not actually played in the game. On these occasions, the notes to the game will explain what should have been played."> Again we have to ask if this describes today's POTD. And again we have to conclude that it doesn't. If 18. Bf6 isn't what should have been played, it should have said so in the notes to the game. If this is meant to be a spoiler then it doesn't follow's CG's own rules for the puzzles. Maybe these rules need rewriting? I really wish CG would come down from Mount Olympus and walk amongst us mortals for a while. What gives with today's POTD guys? |

| Jan-25-12 | | JG27Pyth: gofer <I would normally expect a spoiler to throw up a "winning" move that leads to a loss. <Bf6> is not unsound. It just doesn't win. Not really a spoiler then...> I agree that it's not a spoiler, at least not a good spoiler. A good spoiler should be tempting combination with fatal-flaw-exclam defense leading to loss. This POTD just feels cooked. That said, according to the allseeingallknowing eye of Houdini 1.5, Bf5 is NOT a good move, not the best move (or second best, or third etc.)! It throws away white's advantage to 0.00 -- White has several moves to maintain advantage, Houdini's fav, at +0.45 was 18.c4!? Why? I don't know why I'm merely a feeble wet-carbon "life-form" -- a rust bringer -- disgusting -- unworthy -- But I believe in my electro-mechanical overlord and it knows all -- I believe. |

 | | haydn20: 18...Bf5 may not have been so easy to find in blitz! Seems like AA might have played 12. c4 with an attack. Then again, Black avoids this whole mess with 17...Rfe8. (Count me among those finding 18. Bf6 and not the defense--but I didn 't mind the spoiler or cook, whichever.) |
|
| Jan-25-12 | | JG27Pyth: Am I the only one who thinks Prague Blitz '43 sounds like a WWII event. Alekhine, Keres, Boguljubow all played in Nazi sponsored events during the war. The web informs me that the Prague tournament began with players lining up and "greeting" Hitler (Was he there? Handshakes? Or does greeting perhaps mean 'sieg heil' saluting?) But did the term blitz precede Blitzkrieg? Blitz entered the English lexicon with blitzkrieg I'm almost certain. But perhaps the Germans always called 5 minute chess lightning chess. |
|
| Jan-25-12 | | JG27Pyth: <Am I the only one who thinks Prague Blitz '43 sounds like a WWII event.> I meant it sounded like an actual WWII battle; obviously it was a WWII event, a chess event. |
|
| Jan-25-12 | | doubledrooks: I found 18. Bf6 but could find no win after 18...Bf5. |
|
| Jan-25-12 | | offramp: Well done, Sasha! |
|
Jan-25-12
 | | Marmot PFL: I doubt there is any win after 18 Bf6 Bf5, but black was one of those grab first, think later types that simul givers love. |
