|May-29-07|| ||ounos: <Richerby>, <boprael>, thanks, I couldn't make sense out of the comments! :-)|
|May-29-07|| ||realbrob: I got 26..Rh1+, but White chose the "easier" win for White (27.Kxh1 Qxh3+ and forced mate in 1 move). It was more difficult to spot 27.Kg3 Qg4+ 28.hxg4 h4#.|
Sometimes I wonder why a strong player doesn't resign rather than playing a move like 27.Kxh1 which leads to forced mate in 2..
|May-29-07|| ||nimzo knight: If white has an extra rook. There is no puzzle at all ;)|
|May-29-07|| ||Gilmoy: <TrueBlue:> We feel your pain. I had help -- I won a game once (blitz-ish on pogo) with a similar long pin and Q "sac" (not really, since his g-pawn was pinned), so that pattern leaps out at me now. Winning by Q sac, even a faux one, tends to be a great mnemonic device :)|
As I recall, I blundered an R to his Bish^H^H^H^Hbrilliantly sacked the exchange to steal the long diagonal from him. Soon thereafter, with his K helpfully on h1, I saw the cute Qh3 faux sac. My killer move was first Bd6! to surreptitiously double on h2 -- he remained blissfully unaware. When I uncorked the Q move, his scalp crawled north twice: (1) I'm so pinned (2) I can't even defend h2. There followed Kg1 Qxh2+ and a swift 1-square king hunt (or is that redundant?)
Another lesson I took from that game: Fight back, nobody ever won a game yadda yadda. Bril(ahem)liant!
|May-29-07|| ||YouRang: Okay, I found 26...Rh1+ right away, and if 27. Kxh1? then 27...Qxh3+ & Qxg2#.|
So, I expected white to play 27. Kg3, and I spent the longest time trying to figure what to do next. I was just about to punt when, as a last gasp, I looked at the queen's only check: 27...Qg4+!!. Of course then 28. hxg4 h4#!
Very pretty combination - tricky for a Tuesday though.
|May-29-07|| ||Crowaholic: I saw ..Rh1+ Kxh1 ..Qxh3+ and mate quickly but didn't find ..Qg4+!! after White declines the sac. This sort of pin in mating attacks is essential, I've only studied 6 games from Kasparov's My Great Predecessors by now but these pins seem quite common in high level play, at least as a latent threat. Anyway, I considered ..h4+ after Kg3 but that's not much use without the additional rook on the 8th (the score and diagram were already corrected). ..Qg4+ hxg4 ..h4# is a very nice finish, though.|
|May-29-07|| ||siu02jm: yourang <27...Qg4+!!. Of course then 28. hxg4 h4#!>
hey thats what i have been missing.|
|May-29-07|| ||Duque Roquero: <Sometimes I wonder why a strong player doesn't resign rather than playing a move like 27.Kxh1 which leads to forced mate in 2..>
27. ♔g3 leads to forced mate in 2 as well.
|May-29-07|| ||kevin86: I think I see a flaw in one of the variations: 27 ♔g3 ♕xh3+ 28 gxh3 h4+ is nOT mate because of ♔g4 How does black win?|
|May-29-07|| ||Crowaholic: A missed opportunity for a similiar and very interesting (quality) sacrifice was discovered by user Shams in S Kriventsov vs J Shahade, 2003.|
<kevin86: I think I see a flaw in one of the variations>
I tried that line too but nothing came of it. The trick is that Black plays 27. ..Qg4+, not ..Qxh3+. Now after 28. hxg4 (only move) h4#, there is no 29. Kg4 because g4 is blocked by a friendly pawn.
|May-29-07|| ||goodevans: <Duque Roquero: 27. Kg3 leads to forced mate in 2 as well.> Yeah, but not as obvious as for 27 Kxh1 so I think 27 Kg3 might have been worth a punt for white. After all, if Kramnik can overlook a simple mate in 1 (vs. Deep Fritz) then lesser mortals are capable of missing more complex ones.|
|May-29-07|| ||playground player: Very obliging of Black to play Kxh1! Wish my opponents would make moves like that. Kg3 gave me tons of trouble. I did not find Qg4+ leading to mate; but what's wrong with Qg6?|
|May-29-07|| ||waddayaplay: I completely missed it, instead trying to get Qxh3 to work.|
|May-29-07|| ||siu02jm: <kevin86: I think I see a flaw in one of the variations: 27 Kg3 Qxh3+ 28 gxh3 h4+ is nOT mate because of Kg4 How does black win?>
not 27..Qh3, the key is Qg4!!|
|May-29-07|| ||siu02jm: <goodevans: <Duque Roquero: 27. Kg3 leads to forced mate in 2 as well.> Yeah, but not as obvious as for 27 Kxh1 so I think 27 Kg3 might have been worth a punt for white.

Same here, I ruled out Kxh1 as immediately losing. You are right there is something serene about Qg4+ eventhough its a mate in 2. Could be argued that the opponent didn't want the black to have a flashy finish. Imagine if one regigns in the middle of 'immortal game'.
|May-29-07|| ||LIFE Master AJ: I was going to say that this was way too dificult for a Tuesday puzzle, but the official CG post (see above)
already covered that.

White: Kh2, Qc5, Be3, Rb6; pawns - a2, c2, c4, f2, g2, & h3.
Black: Kf7, Qe6, Bb7, Rd1; pawns - a6, e5, f6, g7, & h5.
Black to move. (26... ???)
|May-29-07|| ||Kleve: Yeah... I saw Rh1+, an easy enough mating pattern if Kxh1. But I couldn't find the winning line after Kh3 for the life of me!|
Qg4+!! Fantastic. Thanks for your analysis, all!
|May-29-07|| ||schnarre: Rh1+ was obvious enough, though Qg4+! took longer. A nice finish!|
|May-29-07|| ||Tactic101: Seen this sort of puzzle before, so the answer came instantly.|
|May-29-07|| ||iceman77: The bishop on b7 prevented the pawn to take on the queen on h3. A fairly easy one but one can totally miss it.|
|May-29-07|| ||Fezzik: Now that the game score has been corrected, 27...Qg4! (after 27.Kg3!) is not only the prettiest way to win, but the only way to mate! |
The corrected puzzle is hard enough to warrant a Thursday slot, but I was happy enough to see it today. Maybe this week will be full of tough puzzles!
|May-29-07|| ||Beancounter: Did the editor wake up with a toothache this morning? This is a tuesday!!|
|May-29-07|| ||fm avari viraf: Ziaur Rahman, the first GM of Bangladesh, finishes off with one of the prettiest combinations. Here, he first sacrifices his Rook & when grabbed White is mated in two & if the White King moves to g3 then the stunning Queen sac comes 27...Qg4+ 28.hxg4 h4#|
|May-29-07|| ||patzer2: The daily puzzle solution 26...Rh1! is a decoy which allows the Black Queen to exploit the pin and force mate-in-three after 27. Kxh1 Qxh3+ 28. Kg1
