| Dec-02-11 | | agb2002: White has the bishop pair for a bishop, a knight and a pawn. The black castle is not properly defended, in particular the light squares. This suggests 30.Qg6, threatening 31.Qxh7#: A) 30... hxg6 31.hxg6+ Kg8 32.gxf7+ Kxf7 33.Be6+ Ke7 (33... Kg6 34.Bf7#) 34.Bg5#. B) 30... Rxf5 31.Qxf5
B.1) 31... Kg8 32.Qf7+ Kh8 33.Qxf8+ Rxf8 34.Rxf8#.
B.2) 31... Be7 32.Qf7 Qc8 33.h6
B.2.a) 33... gxh6 34.Bxh6 Rg8 35.Rhg1 + -.
B.2.b) 33... Bf6(8) 34.hxg7+ Bxg7 35.Rxh7+ Kxh7 36.Rh1+ and mate next. B.3) 31... Qc8 32.Qxc8 Rxc8 33.Rf7 and the endgame looks lost for Black. C) 30... Na3+ 31.bxa3 only loses the knight. |

| Dec-02-11 | | syracrophy: <redmaninaustin: I had 32.Rh8+ Kxh8 33.gxf7 threatening both fxe8(Q) and Rh1 mate. Is this also a winning line?> No, since Black has the desperate reply 33...♖e1!? 34.♖xe1 g6! freeing his ♔ and White finishes with only a ♖ for the ♕. But the most important reason is that White has direct mate with the original line ;) |
|
| Dec-02-11 | | Poulsen: I did also consider 30.Dg6 as the first move, but ... ... I think we all are "helped" by being tolded, that there is a puzzle in the position. That sort of invites us to look for flashy moves. OTB I might have taken a look at 30.Bxh7. |
|
| Dec-02-11 | | Bobby Fiske: Found Qg6 quickly simply because I usually check out the spectacular lines first in such puzzles. However my plan was 32. Rh7 with mate after double rooks in h-file. It seems to work, but I didnt double check with a computer. Anybody who can verify this, please? |
|
| Dec-02-11 | | bachiller: I want to point out the role of the dormant bishop in c1. Apparently, he does nothing relevant, but is a key element both defending his king and ready to kill the enemy. Beware the quiet soldiers! |
|
| Dec-02-11 | | morfishine: <30.Qg6!> leads to a beautiful mate if Black accepts the offer: After <30...hxg6 31.hxg6+ Kg8 32.gxf7+ Kxf7 33.Be6++
click for larger view
Its this double-check that kills. My solution continued <33...Ke7 34.Bg5 mate> I didn't see the alternative <33...Kg6 34.Bf7 mate> What this all means is Black can't accept the offered Queen but must toss an exchange with <30...Rxf5>. Excellent post <jimfromprovidence> in covering the <31.Qxe8> variation. From what I can tell <31.Qxf5> is sufficient, though not as powerful as <31.Qxe8>. The immediate threat is 32.Qxf8+ Rxf8 33.Rxf8 mate. 31...Kg8 doesn't help black due to 32.Qf7+
However, Black can hang around for awhile with <31...h6> |
|
| Dec-02-11 | | cocker: A very fine finish, but several other moves will probably win for White; e.g. 30 Bg6 or even 30 Bxh7. This makes it harder to search for something even better. |
|
| Dec-02-11 | | sevenseaman: Crafty does not take the Q at g6 with the h P. It prefers 30...Rxf5, going an exchange down. This surprise is easily dealt with. No terrors as 31. Qxe8 Qxd5 (best, Rxf1 is no good)32. Qxf8+ Rxf8 33. Rxf8+ Qg8 34. Rxg8 Kxg8 and White is left with enough for a win. ( <jimfromprovidence > has also disposed of this situation) |
|
| Dec-02-11 | | Al2009: It was also playable
32. Be6! and White forces a more elegant mate
if 32...Ne5 33. gxf7+ Nxf7 34. Bxf7#
if 32...Rxe6 33. gxf7#
if 32...Be7 33. gxf7 Kf8 34. Rh8# |

| Dec-02-11 | | sevenseaman: <morfishine> <From what I can tell <31.Qxf5> is sufficient, though not as powerful as <31.Qxe8>. The immediate threat is 32.Qxf8+ Rxf8 33.Rxf8 mate. 31...Kg8 doesn't help black due to 32.Qf7+> You will be surprised the line above does not work. It has to be 31. Qxe8, the base rank R. Black must not be given a chance to play Qc8. |

It seems to work, but I didnt double check with a computer. Anybody who can verify this, please?> That was my first look plan also, but it's too slow. White has given up a Queen, so it's imperative all moves be with check. 32...Nd2+ ends White's fun and might be winning for Black. 32..Qxd5 is also a defense for Black. |
|
| Dec-02-11 | | JG27Pyth: I didn't consider the 30.Rxf5 defense -- which means I didn't really solve this thing! I did find an alternate solution at move 32. (Unless I'm mistaken) -- 30.Qg6 hxg6 31.hxg6+ Kg8 32.Be6! A)...Rxe6? 33.gxf7# B)...Be7 33.Bxf7+ Kf8 34.Rh8# C)...Ne5 33.Bxf7+ Nxf7 34.gxf7# |
|
| Dec-02-11 | | et 9: is the lame 30.Bg6 still winning? There seems to be time for white to play a simple skewer wining the exchange and proceeding with small advances. Black doesn't have an attack, does he? BTW, where is "Once"? He is truly missed. |
|
| Dec-02-11 | | SketchQuark: I see:
30. Qg6 hxg6
31. hxg6+ Kg7
32. Be6
which looks crushing for white. |
|
| Dec-02-11 | | CHESSTTCAMPS: White has the Horwitz bishop pair and controls splendid open lines towards the black king. The black rooks and bishop are all passive, doing nothing to defend h7. The right candidate came to me immediately. 30.Qg6! attacks not only h7, but the two rooks that don't defend each other. The forcing lines are easy to calculate: A) 30... hg 31.hg+ Kg8 32.gxf7+ Kxf7 33.Be6+ Kg6 34.Bf7#! A.1) 33... Ke7 34.Bg5#
B) 30... Rxf5 31.Qxe8! ([Qxf5 allows Qc8] and the double threat of Qxf8+ and Rxf5 can't be met) Rxf1 32.Rxf1 wins. C) 30... Na3+ 31.bxa3 does nothing to prevent the attack in lines A & B. D) 30... Nd2+ 31.Bxd2 Rd1+ (to try to avoid the mate in A.1) 32.Bxe1 hxg6 33.hg+ Kg8 34.Be6# E) 30... other 31.Qxh7#
Did black play until mate? Time for game review.... |
|
| Dec-02-11 | | SketchQuark: Meh, my line is slightly less efficient than the game continuation, but still mating according to computer analysis. Though perhaps its worth noting that my line doesnt really require the dark-squared bishop, should this pattern arise with one less piece. |
|
| Dec-02-11 | | Patriot: I tried to do a "quick solve" on this since I don't have a lot of time today. I was thinking 30.Qg6 hxg6 31.hxg6+ Kg8 and decided on 32.Rh7 preparing to double rooks and mate that way. I also noted the possibility of 32.gxf7+ Kxf7 33.Be6+ and didn't see the nice finish within the few minutes I looked at this (33...Ke7 34.Bg5# OR 33...Kg6 34.Bf7#). <morfishine> Great job on the puzzle! |
|

 | | gawain: I guess things fall into place fairly nicely once you try Qg6! But it seemed hard for a Thursday. I think Ms. Zawadzka must have foreseen the Q sac and the whole mating attack as far back as move 25. Kudos to her! |
|
| Dec-02-11 | | Nemesistic: I didn't look too long,but i thought this would have started with 30.Bg6! Never thought about Qg6! |
|
Dec-02-11
 | | FSR: The flashy 30.Qg6! looks crushing:
30...hxg6 31.hxg6+ Kg8 and now it seems that White wins with either (a) 32.Rh8+ Kxh8 33.gxf7 threatening both 34.Rh1# and 34.fxe8(Q) or (b) 32.Be6! Rxe6 (32...Be7 and 32...Ne5 hold out a move more) 33.gxf7# 30...Rxf5 31.Qxe8 Rxf1 32.Rxf1 and wins. |
|
Dec-02-11
| | FSR: Hmm, rilkefan and I had the same erroneous thought - thinking that White had two ways to win (32.Rh8+??, which loses, or 32.Be6!, which really does win), but missing the nonstop checking solution in the game. |
|
| Dec-02-11 | | kevin86: I missed this brilliant finish-I opted for Bxh7--- |
|
| Dec-02-11 | | Al2009: However, notice that 32.Be6! is more "elegant", but is a bit "slower" because Black can play also 32...Nd2+ 33. Ka1 (33. Bxd2 Qxc2+ etc. ) Nb3+ 34. axb3 and mate takes 2-3 more moves for White than 32. gxf7+ as in the game. |
|
| Dec-02-11 | | pericles of athens: i immediately noticed a nasty rook skewer - "attack unprotected pieces" right? I looked, however, at bishop g6. Perhaps I wasn't bold enough to consider Qg6. |
|
| Dec-02-11 | | BOSTER: After 30.Qg6 if black accept this gift they play hxg6,and after 31.hxg6+ Kg8 we have the usual picture in Sicilian, when black king has his shelter between two opened ("f" & "h") files.
32.Bd6,pinning rook on f7. This rook has only one defender, and three times attack.
You can't protect it(you can't bring two defenders during one move in this position),
and game is over. If after 30.Qg6 black play Rxf5, 31.Qxe8 and bishop f8 under attack by rook f1 and queen e8. |
