|Sep-01-11|| ||kevin86: That was an easy one:sac the bishop at f6 and if black's rook tries to stop mate,it is decoyed by Rd8.|
|Sep-01-11|| ||Coigach: The trouble with puzzles from games played at the World Cup this week is that they can be very easy for those of us who have been watching the tournament!|
I'm really enjoying the live coverage of the World Cup in English and HD on http://chess.ugrasport.com/ Live video of the playing room with excellent commentary and analysis. Highly recommended, and if you can't get to a computer between 10 am and about 3 pm UK time, it is possible to skim through the video later.
|Sep-01-11|| ||HowDoesTheHorsieMove: Wow, a Thursday! I never get Thursdays...until now.|
|Sep-01-11|| ||sevenseaman: <doubledrooks> <21. Bf6 Rg8 22. Rd8 >
Or <21...gxf6 22. exf6 Rg8 23. Rd8.>
and mate is coming up.
Or 21. Bf6 Rg8 22. Qxg7+ Rxg7 23. Rd8 and the mate is still
coming up. There are many more ways to mate.
Isn't it fun you can write the obituary in may be 8 to 10 ways;
the position is very versatile.
Unfortunately this is the only game <A. Grischuk> has won in the WC so far and he may not qualify for the next round.
|Sep-01-11|| ||Marmot PFL: I recall another puzzle like this, with a piece sacrifice to mate using a pawn on the 6th rank. 21 Bf6 gf (21...Rg8 22 Bxg7+ Rxg7 23 Rd8+) 22 ef Rg8 23 Rd8.|
Have to say black's play seems amatuerish, moving the same pieces repeatedly without ever developing QB or QR.
|Sep-01-11|| ||ooda: Easy for a Thursday. I saw they key straight away then it took me about 20 secs to find Rd8 if ...Rg8. I don't always get Thursday and its nearly always a real struggle at least.|
|Sep-01-11|| ||Imerasmusdurer: I am patting myself on the back. I found the solution almost immediately. Two months ago, I would not have been able to find the solution in 10 minutes of trying, so I am actually making some slight improvement in tactics. Chess Tempo has really helped. Try it!|
|Sep-01-11|| ||CHESSTTCAMPS: <FSR: Incidentally, when I saw the position of Black's kingside pieces, and White's pawn on e5, queen on g4, and bishop on h4, I thought of this brilliancy: Waitzkin vs E Frumkin, 1987. Definitely worth playing over if you haven't seen it.>|
Funny you should mention this. Last week, one of the kids at my once-a-year Chess/Table Tennis camp was playing back this game from ChessMaster (Josh Waitzkin's Academy section) and I was looking with interest over his shoulder, trying to work through the combination before commentator Josh got there. Ashamed to say (considering that I utilize the product so much) that I'd actually never played through this particular game before. Needless to say I was impressed with this combination coming from a 10-year-old, yet I missed the similarity with the POTD position until you mentioned it. It wpuld have made a more challenging Thursday POTD for those not familiar with the game.
<sfm: Again thanks to <David2009> for the interesting crafty-links. Of course there is no reason to think that black can hold after 20.Qg4. He is hopelessly behind, and white has Q,B,N+R ready for attack.>
I second that. I found a different plan to play the position (not necessarily more effective, but a bit flashy) - to deny the defense Bf8 by an exchange sac.
After 20... Qxb2 I played against Crafty 21.Bf6 g6 22.Qg5 Re8 23.Rd6! Bxd6 24.ed h6! 25.Qh4 Qd2 26.Nf4! Kh7

27.Bg5 Kg8 28.Qxh6 Qd4 29.Nh5! gxh5 30.Bf6 Qxf6 31.Qxf6 and the rest is easy enough, but I'll give a few more moves for reference.
e5 32.Qg5+ Kf8 33.Qh6+ Kg8 34.Qxh5 e4 35.f4 Re6 36.f5 Rxd6 37.f6 and black has to give up the rook to stop mate.
|Sep-01-11|| ||Jimfromprovidence: The puzzle itself was pretty staightforward but for the move before I liked 20...Qb4. |

I'm not sure if it's good enough to stop white, but it looks decent. I'd be worried about Rd3 at some point though.
|Sep-01-11|| ||gawain: I'm rather pleased with myself for seeing this. It's a nice sequence. There weren't really that many candidate moves, but....|
|Sep-01-11|| ||Eduardo Leon: <21.♗f6 gxf6>
21...♖g8 22.♖d8 only accelerates the inevitable.
<22.exf6 ♖g8 23.♖d8>
And 24.♕g7# can only be delayed two more moves.
|Sep-01-11|| ||BOSTER: <SimonWebbsTiger> <I am one of many who saw Bf6 when it was played>.
But it was much better if you saw Bf6 before it was played.|
|Sep-01-11|| ||Seaholme: 2 bad i saw this when it was played, no problem "solving" it then...|
|Sep-01-11|| ||LIFE Master AJ: I went with 21.Bf6!
One idea is 21...Rg8; 22.QxP/g7+! (Rd8+ is next.)
|Sep-01-11|| ||SuperPatzer77: <Patriot: Ouch! 21.Bf6 was right at the top of my candidate list very early but after 21...gxf6 22.exf6 Rg8 I missed the simple pin 23.Rd8!>|
<Patriot> Yeah, indeed - it is a big ouch!
21. Bf6! gxf6, 22. exf6 Rg8, 23. Rd8! Qe8, 24. Rxe8 Bf8, 25. Rxf8 (capturing two pieces (queen & bishop) and still pinning the Black rook at g8) so, Black has no defense against Qg7#.
|Sep-01-11|| ||estrick: <sfm: Again thanks to <David2009> for the interesting crafty-links. |
I'm pretty sure I've never seen a sequence of rook moves like this before. That is simply an astounding tour de force. And to think that the best (though ultimately doomed) defense, per Crafty, is to DECLINE Taking that 'tornado of a rook' at each opportunity.
|Sep-01-11|| ||morfishine: <David2009> Thanks for including me as a "regular" as that is esteemed company. Sometimes I feel I'd like to trade a whole week of solving the POTD from Mon thru Sat, for ONE Sunday! I think I've only got 2 or 3 Sundays correct in 5-months. Thanks though, means much. Best, Morf|
|Sep-01-11|| ||ColeTrane: so essentially 20. ...Kh8 did nothing|
|Sep-01-11|| ||sevenseaman: Whatever people do they mostly say or imply < I got it or I missed it >.|
But <SWT> has really worked in a quantum jump in semantics when he says;
I am one of many who saw Bf6 when it was played.>
It took <Boster> pointing it out for me to really notice the subtlety of the nuance. Depend upon it, the language does improve as we travel in 'time'.
|Sep-01-11|| ||sfm: <Jimfromprovidence: The puzzle itself was pretty staightforward but for the move before I liked 20...Qb4>|
Nice try, and seems better that -,Qb2. But anything planned on 21.Nf4 ? As -,Be7 22.a3,Qc5 23.Rc1 looks resignable. And without 21.-,Be7, well, it still murder-by-f6. As Churchill said "Never in the history of Chess has so many black pieces done so little for so few", as <CHESSTTCAMPS> alternative also demonstrates.
<estrick: I'm pretty sure I've never seen a sequence of rook moves like this before.>
LOL! Didn't even think of that. That spiral-movement is really a 'tornado'!
Where did Black go wrong? Like in yesterday's game, e5 really made the opponent cry. Very instructive.
|Sep-02-11|| ||LIFE Master AJ: <<Aug-28-11
bright1: 21. Bf6 is great move. After 22. exf6 Rg8 23. Rd8 then nothing can stop Qg7# on the next move.>> |
This is not entirely true, (as) Black can play "give-away" with his DSB and Queen ... but your point is well taken ...
|Sep-02-11|| ||njchess: I'm really not sure how Black expected to win, much less draw this game. After 14. ... Nc6, which is essentially forced, there is little if any counterattacking possibilities with his position. His king side is seriously weak of defenders and the rest of his pieces are basically inactive. The fact that the game ends after White's 22nd move shows you how anemic Black's position was.|
Not much of puzzle since I caught the game earlier. Though I think it would be fairly easy without prior knowledge.
|Sep-02-11|| ||sevenseaman: Happy to learn <Grischuk> is through to the next round of the World Cup 2011.
He plays <Morozevich>.|
|Sep-02-11|| ||LIFE Master AJ: <<<Sep-02-11 sevenseaman:> Happy to learn <Grischuk> is through to the next round of the World Cup 2011. He plays <Morozevich>. >>|
Now that will be a good match-up!!!
|Sep-06-11|| ||Domdaniel: Black's play wasn't so terrible -- Grischuk just made it look bad by seeing further into the position, especially around move 16.|
Black is clearly aware of his undefended kingside, and the need to do something about it. So he plays the reasonable 16...Nd4 - an active move, seemingly grabbing some initiative. He possibly expected the reply 17.Bd3 - White preserves his light square bishop and threatens mate, but black can defend with ...g6.
Instead, Grischuk ignored the attack on the Be2 and played the precise and deadly 17.Bh4!. He's not interested in the b1/h7 diagonal after all, and he won't need the LSB: he plans to attack on the *dark* squares.
17.Bh4 drives the Queen to d7, which allows White to take over the d-file. Meanwhile pressure is maintained on f6/e7/d8, inhibiting Black's defence.
The whole maneuver is a perfectly timed attacking sequence, in which the 'puzzle' combination is merely a final flourish.
