| openingspecialist: after failing to find the solution thinking the idea was Rd4 Qe5 Rh4 i began to amuse myself with the line Bh4 g3 Bxg3 hxg3 Rh5+ Qh4 Rxh4+ gxh4 Qxe1+ Kg2 Qxc1 Kg3 etc and i found the coolest position 
click for larger view all of the moves made by white where what i believe are roughly its best and black just had some fun. last moves were Kg7 a7 e4 a88Q Qf3-g2# |

| benjinathan: I saw the move; thought it was mostly the right move and the move I would have made; but did not see how it won. Pathetic. I agree with <znprdx>. |

| patzer2: For today's Wednesday puzzle solution, Walter Browne cleverly exploits White's weak back rank with 32...Bh4!! The move 32...Bh4!! creates a double threat, as, in addition to the obvious and compelling threat of 32. h3 33...QxR+  , Black also threatens 32. Rg1 Qxg1+! 33. Kxg1 Rd1+ 34. Qe1 Rxe1# and 32. g3 Bxg3! 34. hxg3 Rh4+ . |

| awfulhangover: Wow, I got it 100%! But it took some time to find it ... |

 |
| playground player: I had 32...Bd2. White can't play Bxd2, because Black would answer with 33...Rxd2, threatening mate by Qxg2. To deal with that, White would have to play 34.Rg1, answered by ...Re2, driving the White Queen off the e-file. I think Black eventually wins with this. If White does not play Bxd2, what else is there? |

|
| patzer2: For a more difficult winning move, Browne's double attack 31...Qf2! attacks and pins the loose Bishop (and the a-pawn it's protecting) while also setting up the threat of 32. Bc1? Bh4! . White can put up more resistance with
32. Bc3 Qxa2  or 32. Be5!? Bh4 33. Bc3
Bg3 34. Qg4 Be5 35. Qc4 Rc5 36. Qxc5 Qxc5 37. Bxe5 to . However, Black's advantage, even with best play by White after 31...Qf2!, is probably decisive. |

| YouRang: Crumb. I saw 32...Rd4, which looked like a perfect queen deflection to exploit the vulnerable back rank, and then I came here to announce how quickly I "got it". Of course, I failed to pay attention to 33.Qa8+ Kh7 34.Rg1, which still leaves black better off, but not nearly as much as I had in mind. :-p |
|
Aug-20-08
|
| patzer2: <playgroundplayer> After 32...Bxd2, White can and should play 33. Bxd2, since 33...Rxd2 34. Rg1 still gives him fighting chances for a draw. From here play could continue 34...Rxa2 35. Qa8+ Kh7 36. Qe4+ g6 37. Qf4! Qa7! 38. Rc1 Qe7 39. Qe5 , when Black has a clear advantage with the extra pawn but forcing the win is not so easy. |

| chrisowen: Looking up it doesnt take an Aristotle to realise the massive logic of black's army. Bc1 is an oily rag that you'd throw away. |

| kevin86: This is certainly NOT my week to be 8/8-.
How about the brutal variation:
33 g3  xg3 34 hxg3  h5+ 35  h4 xh4+ 36 gxh4 xe1+ 37  h2 xc1 and black is ahead a mere queen-and a pawn |

| mkrk17: I got Bh4, but i must be frank that this is a standard position in CT-ART 3.0 and the moment i saw the position, i felt it looked familiar. After that, it didnt take more than a minute to figure that Bh4 cracks up whites' position. |

| Once: How come so many of us struggled to spot 32. ... Bh4? But when we found it, or it was pointed out to us, we all slapped our collective foreheads with a cry of "of course"? Presumably because it is apparently a non-forcing move - doesn't give check or capture a piece. Perhaps have become a little too programmed to look for puzzle-type forcing moves? |
|
| Aug-20-08 |
| Waitaka: Yes, I got it, but after reading <dzechiel> post I realized that there are more on the position that I saw at first. |
|
Aug-20-08
|
| patzer2: Perhaps an instructive lesson from today's puzzle is that in seeking out forcing moves for a potential combination, don't overlook moves not involving a check or capture -- especially moves threatening unprotected pieces (e.g. 31...Qf2! ) or moves threatening under-proteced pieces (e.g. 32...Bh4! ). |

| benveniste: Great puzzle. I spent quite a while looking at Rd4 and I suspect many others did as well. It feels right to deflect the queen, and to do so in such a dramatic way just has to be a puzzle solution, right? Wrong. Bh4 is natural and logical. Except for the potential of a queen sac after Rg1, one might even call it boring. But a boring win is still a win. |

| TheaN: 3/3
Geez this one took me TOO long. That seems obvious, as Black seems to gain something from a bank rank, but does not do this on move 32. The played move is sneaky, but so effective. I ruled out Queen, Rook, and other Bishop moves as they would actually lighten up the situation: Rook moves allow at least Qa8, Queen moves don't threat anything more on any square compared to her on f2, and all the Bishop interposions are well defended by White's last move, Bc1. -ML-
<32....Bh4!> simple, but great, different than yesterday. The amount of moves available to Black make it to find the only winning move a great move. /A\
A couple of losing Rook moves leading to mate can be considered one variation. I include Rook undefending moves by the Queen. <33.Rf1 Qxf1 0-1>
<33.Re2 Qf1 0-1>
<33.Re3 Qf1 0-1>
<33.Rd1 Rxd1 34.Qe1 Rxe1 0-1> <33.Qxd5 Qxe1 0-1>
/B\
<33.Rg1> seemingly the saving move for White. Nuh-uh. <33....Qxg1! 34.Kxg1 Rd1 35.Qe1 Rxe1 0-1> /C\
<33.g3> is one critical variation, blocking the double attack on e1. <33....Bxg3! 34.hxg3> or else mate on h2 or mate on the back rank. Qh4 is simply met by Bxh4, White had to consider that earlier. <34....Rh5 35.Qh4 Rxh4 36.gxh4 Qxe1 37.Kg2 Qxc1 > ouch. /D\
Anything else by White that doesn't protect the Rook or blocks the Bishop makes it go down the drain. But protecting the Rook won't work either in this case. Compared to A, B and C however, it's better than a mate or a full Queen. <33.h3 Qxe1 34.Qxe1 Bxe1 > <33.Bd2 Rxd2 34.Rg1 Qxg1 35.Kxg1 Rd1 36.Qe1 Rxe1 0-1> mate can be prolonged by ridiculous move like 34.Qe2 but I'll not consider them: Bd2 just loses. /E\
<33.Qxh4> last but not least, White has to consider Q vs B. Completely losing, but mate, a full Queen, a full Rook, or a full Bishop with the attack still going, are far worse for White. 33.0-1 is best. <33....Qxh4 > |

| fritochip: Well, I feel better about thinking it was Rd4. My thinking was that it cut off the one square the white queen could go to to protect herself and the rook, b4. I think that I would have played Rd4 OTB and win. So I can take some solace. Most of these puzzles, even the ones I get right, I would never play it that way OTB. |

| PuzzleMaster: Thu 2008.08.20 (Black to play. 32 ... ?)
Candidates: 32 ... Bh4, 32 ... Rd4
A) 32 ... Bh4 wins R (33. Rg1?? Qxg1+ 34. Kxg1 Rd1+, etc. ) B) 32 ... Rd4 33. Qe5 unclear
Wow, that took me forever to solve. |

| PinnedPiece: Rats.
I was certain that the bishop should move to D2, then if 33. Rd1 Bxc1
or if
33. Bxd2 Rxd2 with some fending off of a Q attack on the 8th rank, but ultimately mate on g2. Ugh.
