| Jan-13-12 | | LoveThatJoker: I would like to point one major line of interest that favours White after 21. Qh7+ Kf8 22. Qg6 Bf5 23. Qxf5 hxg5 24. Nxg5 If here Black plays 24...Qg7 White wins by 25. Ne6+ Rxe6 26. Qxe6 Nd7 27. Qxd6+ when White has the better of it with Rook+three pawns versus two knights. LTJ |

 | | whiteshark: So it's a forced mate in four. |
|
| Jan-13-12 | | Penguincw: Black's forces do nothing to help stop mate in this game. |
|
| Jan-13-12 | | Rosbach: Looked at both Ne5 and Qh7+. However, didn't catch the devastating attacking potential of Ne5. If Black attempts to retreat to f8 instead of dxe5 then 21...Kf8 22. Ng6+ and Black's queen is lost. The continuation could be 22...Kg7. 23. Nxe7 Rxe7 24. Qh7+ Kf8 25. Rxf6+ Nxf6 26. Qh8#
(or more ineffectively 26. Rxf6 Ke8 27. Qg8+ Kd7 28. Qe6+ and Black's rook is lost too) |
|
| Jan-13-12 | | Sassa: Wonderful puzzle! Also, it´s funny to see that the black Rook, Knight and Bishop still are on their initial position by the move 21! |
|
| Jan-13-12 | | Archswindler: <thedarkknight: I found the combination but a little bit flawed
I thought that white had to push 22.d6>
Same here. I missed that after the knight recaptures on f6 it is pinned, so I thought the black queen needed to be deflected from defending f6. Unfortunately, 22. d6 doesn't work because of 22... e4! |

 | | karnak64: The position after move 18 is bewildering. Black has four pieces still on original squares (two have stepped out and come home) and has this crazy pawn shield on the 6th rank before the king. Meanwhile, white is loaded, aimed, and set to fire. What's crazy about 21. Ne5 is that black can capture a Knight five different ways and they all lose. Absolutely gorgeous. |
|
Jan-13-12
 | | Clodhopper: I got the right move to today's position as given. But starting the problem off with 19. Bxg6 would have made it even more challenging. That was a great attacking move. |
|
Jan-13-12
 | | sethoflagos: Black is threatening 21...hxg5 which probably spoils the party. 21.Qh7+ Kf8 22.Qg6 hxg5 23.Nxg5 Nd7 24.Nh7+ Qxh7 25.Qxh7 leaves: 
click for larger view...and black has to find an answer to the threat of Rf3-Rg3-Rxg8# |
|
| Jan-13-12 | | CHESSTTCAMPS: In this middle-game position, white is down a bishop for a pawn on the board, but with all those black pieces undeveloped on the queen-side is effectively up R+N in the local conflict on the king side. The black king's shelter is already badly degraded and the weakened light squares are good entry points for white's queen. Black threatens hxg5. The most forcing move 21.Qh7+ Kf8 leaves white with no good option but to trade queens, but it isn't hard to see that if the Nf3 were not in the way, white would be able to force mate with 22.Rxf6+. This suggests 21.Ne5!! opening up the rooks and giving black the impossible task of defending both g6 and h7: A) 21... dxe5 22.Qh7+ Kf8 23.Rxf6+ Qxf6 (Nxf6 24.Qh8#) 24.Rxf6+ Nxf6 25.Qf7# as discussed above. B) 21... fxe5 22.Qh7#
C) 21... Qxe5 22.Qh7+ Kf8 23.Qf7#
D) 21... fxg5 22.Qg6+ Kh8 23.Rf7 or Nf7+ are equally effective. E) 21... hxg5 22.Qg6+ Kh8 23.Nf7+ Qxf7 24.Qxf7 Re7 25.Qh5+ (to gain time by displacing rook) Rh7 (Kg7? 26.Rxf6! Nxf6 27.Qxg5+ cleans up) 26.Qe8 Nd7 27.Qd8 Black's pieces are tied down and can't stop 28.Qc7 winning the key d-pawn. E.1) 22... Kf8 23.Rxf6+ Nxf6 (Qxf6 24.Qf7+! Qxf7 25.Rxf7#! is prettiest) 24.Rxf6+ Qxf6 25.Qxf6+ Kg8 26.Qf7+ Kh8 27.Ng6# F) 21... f5 22.Rxf5! Bxf5 23.Qxf5 hxg5 24.Qg6+ Kh8 25.Rf7 wins. F.1) 22... hxg5 23.Rf7+ Qxf7 24.Rxf7+ and mate next.
F.2) 23... Qxe5 (/dxe5) 24.Qh7#
F.3) 23... Nf6 24.Qg6+ wins quickly.
G) 21... other 22.Qh7+ Kf8 23.Ng6#
Line E seems to be the best defense, with black's chances for counter-play much lower than yesterday's POTD. Time for review... |
|
| Jan-13-12 | | cydmd: The line selected by Timman is not so crushing if a correct defense is employed, as <David2009> pointed out. The white queen is exchanged by 3 small pieces still keeping a positional advantage for White. However, a win is not clear on White's horizon. The line proposed by <Jimfromprovidence> seems to be the best since it gives an advantage of 2 pawns for White. |
|
| Jan-13-12 | | LIFE Master AJ: First of - please read <dzechiel>'s post first ... (he always outlines most POTD's very thoughtfully). As far back as I can remember - maybe 10 years now - he has been doing this, and because of his steady and concise coverage spanning YEARS - I duly nominated him for the Caissar Award for "Most helpful." (IF this site is really about chess, he should win this category, hands down.) Second, I spent a lot of time on this one ... at first trying to make Qh7+ work. I think that the solution is actually sort of tricky. White must unleash the power of the two rooks and try to get the other Knight involved. To that end, 21.Ne5! is the right move. Now capturing the Knight on g5 leads to a disaster. Obviously, Black cannot open the f-file.
21.Ne5! dxe5; (Pretty much forced, others are really ugly.) 22.Qh7+, Kf8; 23.RxP/f6+!, NxR/f6 : 24.Qh8 ... check and mate. (Qh8#) Black can avoid the mate only by giving away lots of material. Renewed appreciation of Timman. I "grew up" in chess in the 1970's and 1980's. During this period, Timman was a chess force to be reckoned with, at one point clearly in the World's "TOP TEN" players. (http://www.chessmetrics.com/cm/CM2/...) I very clearly remember the old "printed" (do they do that anymore?) FIDE ratings lists of that era, Timman was always (semmingly) one of the best platers in the world, although I also recall he could have one really goood tournament followed by an indifferent result. But at least I rememeber the Timman of that period. |
|
| Jan-13-12 | | rudiment: I explored Nh4 for a while; Ne5 completely escaped me though. And I had gotten them all so far this week! |
|
| Jan-13-12 | | CHESSTTCAMPS: Unlike yesterday, I beat Crafty EGT on the first attempt. Crafty went straight into my E-line: 21.Ne5 hxg5 22.Qg6+ Kh8 23.Nf7+ Qxf7 24.Qxf7 Rd7 25.Qh5+ Rh7 26.Qe8 Bd7 (here my E-line went 26... Nd7, which is similarly difficult for black to get developed) 27.Qd8 Re7 (the tempo I mentioned in my analysis) 
click for larger view28.Rxf6! Re8 29.Qc7 Nxf6 30.Rxf6 h5 31.Rxd6 Ra6 32.Rxa6 bxa6 33.Qxc5 and with all the extra pawns and the inactive black minor pieces, white won easily. |

| Jan-13-12 | | Rook e2: <LIFE Master AJ:> I remember an interview where Timman sais he was clearly 3rd, behind Kasparov and Karpov at one point. But you can also know him as challanger of Karpov when Kasparov and Short decided to play their match not under FIDE. |

Try 25 Rf3 or 25 Rf4, used below.

The threat is 26 Rg4, followed by 27 Nh7+, winning the queen. It's a fun line to investigate. |
|
| Jan-13-12 | | newton296: I went with 21.Nh4 and I think white is winning. never even considered 21.Ne5 pretty sweet mating combo by timman. |
|
| Jan-13-12 | | drnooo: lets face it: after two days, week tops, Owen himself couldnt unscramble his own babble. It makes even less sense for us to do so. Notice how unread
Finnigans Wake is these days, total gibberish, fit for windy suppuration by some Harvard professor bent on boring everyone in the classroom |
|
| Jan-13-12 | | Pawn Derous: Well, I went with Nh4 and congratulated myself too early. But it was wonderful to see how Timman dispatched van Wijgerden's forces before they could all get their pants on. |
|
| Jan-13-12 | | abuzic: 21.?
21.Qh7+ and 21.Ne5 win easily;
while 21.Nh4 gives white a winning endgame.
It depends on one's style of play.
I will look into 21.Nh4, the least favored line:
21.Nh4 hxg5 is the best response for black;
<21...f5 22.Rxf5 hxg5 23.Qc3+ Nf6 24.Rxf6 Kg8 25.Rg6+ Kh7 26.Rff6 Qxe3+ 27.Qxe3 Rxe3 28.Rf7+ Kh8 29.Rg5 Re1+ 30.Kh2 and black cannot effectively prevent Ng6+, Rgg7 and will be mated soon.> 22.Qg6+ Kh8
<22...Kf8 23.Rxf6+ Nxf6 24.Rxf6+ Qxf6 25.Qxf6+ Kg8 26.Qg6+ Kf8 27.Qxd6+ Kf7 28.Qg6+ Ke7 29.d6+ Kd8 30.Qf6+ Kd7 31.Qf7+ Kxd6 32.Qxe8 Bd7 33.Qf8+ Kc6 34.Nf3

this is winning for white>
23.Qh5+ Qh7
<23...Kg7 24.Rxf6 Nxf6 25.Qxg5+ Kh7 26.Qg6+ Kh8 27.Rxf6 Qe3+ 28.Kh1 Qe1+ 29.Kh2 Qe5+ 30.g3 Qxb2+ 31.Ng2 Qxf6 32.Qxf6+ Kg8 33.Nf4 Nd7 34.Qg6+ Kf8 35.Qxd6+

24.Qxe8 Nd7 25.Ng6+ Kg7 26.Ne7 Nb6 27.Nxg8 Qxg8

this must be winning for white. |
|
| Jan-13-12 | | BOSTER: In spite of Heisman's advice "<picking candidates, start with checks"> ,we have clearly understand, that <all Rules> have exceptions.
I don't think that 21.Qh7+ is correct move becase this move is too obvious for puzzle ,and after this you have to <hide> your queen on g6, what means that the speed of attack is getting slow. In such position like <POTD> the best way to put all pressure on the "f" file at once. |
|
| Jan-13-12 | | LoveThatJoker: <JimFromProvidence> Hey man. Good to know that you're analyzing this one with me. I actually did look at the Rf4 idea quite a bit before posting earlier. 25. Rf4 is an excellent practical try. Black's best is 25...Nh6. I'm still liking the simple 25. Qxd6+ though. It's still winning. LTJ |
|
| Jan-13-12 | | GlennOliver: Jan Timman at his best, unlocking a complex position with complete clarity. |
|
| Jan-13-12 | | LoveThatJoker: <BOSTER> 21. Qh7+ is a winning move, dude. Whether it is a simple move doesn't diminish the fact that if you chose 21. Qh7+ coupled with 22. Qg6 you'll have a winning game. LTJ |
