|Oct-07-10|| ||goodevans: I didn't anticipate Anand's 26 ... e3 ;)
(what was he thinking!)
|Oct-07-10|| ||cornholio denali: this is my second encounter with this particular puzzle. the first one was five minutes ago in chess.com's daily puzzle. what are the odds, huh?|
|Oct-07-10|| ||Kwesi: Hey this is the exact same puzzle as on chess.com today!|
|Oct-07-10|| ||castle dweller: Just a small point . . .
- but why did vishy make his last move (e3) and not just resign - with his end so readily apparent??
|Oct-07-10|| ||Patriot: <<castle dweller>: Just a small point . . . |

Remember the movie "Terminator" where the machine couldn't walk but kept crawling? That's what Anand reminds me of here. He's probably using psychology on his next opponent. :-)
|Oct-07-10|| ||castle dweller: Maybe - I thought that maybe he realized he got so bamboozeled that he was givng Lazaro the honor of a clean mate? Anand seemed to be doing OK until about moves 16-17 where he tried to move forward with his Knight only to underestimate the white rooks and the coming assault. The Lazaro's attack is textbook sweet but I'm a little surprized Anand couldn't see it coming better - looks like he fell for it hook,line and sinker even though it wasn't terribly complicated!|
|Oct-07-10|| ||castle dweller: Hey Once - Are you sure your "trip" took you to ancient Rome - to me its looking suspiciously like the corner of 9th and 46th streets (near an off Broadway musical!) Maybe the dial on the machine needs a tweek?|
|Oct-07-10|| ||castle dweller: Alot of those time machines are notoriously known for screwing up the delivery as planned - just a thought!|
|Oct-07-10|| ||cheeseplayer: 4/4 wow long time since i got 4 in a row! phew!
every week i say this is the one!
|Oct-07-10|| ||kevin86: In chess,unlike most other activities,the player has the option to resign before the king is mated and the game over. Here black does the absurd and resigns out of turn to avoid being mated.|
In chess ettiquite,being mated is a no no...
|Oct-07-10|| ||CHESSTTCAMPS: <johnlspouge>
Speaking of forcing/option limiting moves in this puzzle, we shouldn't overlook the importance of the option limiting 2nd move in the combination. Although I saw 25.Rxe6 right away, for some reason, I wanted to follow up with 26.Qg6+ followed by Qd6+, when only a draw is apparent. Then I wasted time looking at other candidates before realizing my oversight.
BTW, <gofer>'s line 25.Qh5 also wins, but ends up transposing to the main line.
|Oct-07-10|| ||scormus: Seems I'm not the only one that went first for 25 Rf6+, expecting 25 ... Ke7 then 26 Re6+ and picking up th combination a move later. I guess I'm simply more comfortable when +ing the K. After all W had nothing to fear from 25 ... Qd3+, had he ?|
If B spoils it by 25 ... Ke8, W can pick up the R on g8 and win routinely, or give back the R and look for a #. I think W would get there in not more than about 8 moves. Be interesting to know if someone can find a way B can wriggle out. But anyway the game sequence is quicker and cleaner.
|Oct-07-10|| ||agb2002: <johnlspouge: I am going to start by saying that I spent more time analyzing 25.Rf6+ than 25.Rxe6...|

The maxim about examining all forcing moves is excellent advice, particularly for the inexperienced. I now believe, however, that an initial analysis to uncover distinguishing features of a position is the best way to direct later, deeper analysis.>
As mentioned in his 'Secrets of practical chess', this is John Nunn's approach and I agree.

<whiteshark>, with his fondness for heavy pieces, once stated that Rs should cut off the opposing K's flight, rather than giving check. The Pe6 will fall with 25.Rf6+, but the immediate 25.Rxe6 prevents the K's flight to d7. This is the position's "distinguishing feature".>
I would say that the most important factor is the possibility of undermining the black king's shield, because it doesn't matter whether the king moves to d7 if the (remaining) white pieces can eventually deliver mate.
Less important factors (but still important) are the defenseless bishops and there are other factors, more or less in between.
<< <CHESSTTCAMPS> wrote : [snip] Or to put it differently, in this case the check is actually not the most forcing move. It took me a bit of analysis to realize this. >
Then again, there are always other ways of looking at things...
Yes indeed. Probably you have noticed that I abandoned the typical approaches (candidate moves, forcing moves, direct pattern recognition, etc.) and use a deductive approach instead, which by the way is the only reasonable method to solve positions like K Berg vs G Jacoby, 2007:

However (oh yes, there is always a 'however', sorry), this approach tends to be very energy demanding, or at least that's my impression.
|Oct-07-10|| ||David2009: L Bruzon vs Anand, 2006 White 25?|
25 Rxe6 looks promising, e.g. (A) 25...Kxe6 26 Qxf5+ Ke7 (if Kd5 27 Qd7#) 27 Qf7+ Kd8 28 e6 (if 28 Qxg8+ immediately Kc7 29 Qxg7+ Kb8 Black has counter-attack possibilities)
Bc6 and White should be winning - there may be improvements in this line; (B) 25...Qxb2 (or 25...e3) 26 Qg6+ Kf8 27 Rxf5#; (C) 25...Qg5 26 Rxf5+ etc (D) 25...f4 26 Qg6+ Kf8 27 Qf5#.
Time to check:
Seems OK. Crafty End Game trainer check of the puzzle position:

Crafty EGT defends with its habitual ingenuity but cannot change the inevitable. Enjoy winning as White!
|Oct-07-10|| ||DarthStapler: I got most of it but I picked 28. Qxg8+ instead of 28. e6|
|Oct-07-10|| ||whiteshark: Anand's play looks as if he has not had enough sleep.|
|Oct-07-10|| ||Fenario: It was a tie-breaker in a rapid tournament, so it was blitz timing or something like it.
The following is from
On day one and in the first semi-final match Anand took on Bruzon. With Anand rated 151 point higher than Bruzon, Bruzon had his work cut out for him that seemed near impossible. However, the Cuban star put on an incredible match, holding Anand to a draw in the first four games forcing them both into tie break matches and the faster time control! In game one of the tie breaks Bruzon defeated Anand with the white pieces keeping everyone on the edge of their seats. It wasn't to last, however, Anand struck back with a win in game two. Game three was a draw and Anand took game four, again playing white. Anand moved on into the finals with a score of 4 1/2 to 3 1/2 over Bruzon.
|Oct-07-10|| ||scormus: <Fenario> thanks for the info. The encounter must have been great to follow.|
<agb2002> as usual a very perceptive commentary. I couldnt see how BK could escape via d7 either.
With all that mischief the BQ might get up to after 25 Rxe6, I'd feeling as good about playing it OTB as I would about scaling a rockface with the nearest point of security several feet below me.

I agree with your floccinaucinihilipilification of technical jargon.
< Probably you have noticed that I abandoned the typical approaches (candidate moves, forcing moves, direct pattern recognition, etc.) and use a deductive approach instead, which by the way is the only reasonable method to solve positions like K Berg vs G Jacoby, 2007 [snip] >
The solution is a capture, the second staple (after "check") of the <CG> school of Forcing Moves, so some might object that deduction is not the "only reasonable method" to solve the position.
I am continuing, I confess, the intent of my previous post, to wave a rojo flag in front of a bull ;>)
I was curious about the "deduction" that led you specifically to 25.Rxe6, rather than the tempting 25.Rf6+. Perhaps it can be explained by temporal economy: the ultimate target of the attack is Pe6, so why waste time by interpolating 25.Rf6+ before 26.Rxe6+, thereby permitting the Black K greater latitude?
< However (oh yes, there is always a 'however', sorry), this approach tends to be very energy demanding, or at least that's my impression. >
Probably, [initial analysis to determine the distinguishing features of a position] is more demanding of mental discipline than energy. In the long run, an initial analysis minimizes mental energy, otherwise you and I would not adhere to it.
(Here, I am assuming you are as lazy as I am :)
|Oct-07-10|| ||turbo231: Another discover that I missed. Anand saw it and resigned.|
|Oct-07-10|| ||Brandon plays: I was thinking for a bit that it was Rf6+, but even though that is cute, it doesn't do much. In game I'd play Rxe6. I'm probably missing something, though. I ran through a few continuations and it was looking good for white though.|
|Oct-07-10|| ||patzer2: For today's Thursday puzzle solution, 25. Rxe6! is a demolition decoy sham sacrifice which, with precise followup, puts Black in a mating web.|
Specifically, 28. e6! , instead of the over anxious and less accurate 28. Qxg8+ , gives White an overpowering attack.
Also winning big is 25. Rf6+ Ke7 26. Rxe6+ Kd7 Qxf5 . While it also involves a sham sacrifice offer of the rook on e6, the tactics and the threats are a bit different than in the game continuation.
|Oct-07-10|| ||M.Hassan: <goodevans 32....Qe1+ 33Rf1 Qe3+ draw>
If you mean draw by perpetual check, it is not because:
and White has more material and has more chance of winning.
|Oct-08-10|| ||TheBish: L Bruzon vs Anand, 2006|
White to play (25.?) "Medium"
White wins with 25. Rxe6! (threatening 26. Qxf5#) Kxe6 26. Qxf5+ Ke7 (or 26...Kd5 27. Qd7#) 27. Qf7+ Kd8 28. e6! and Black can safely resign, facing both 29. Qd7# and 29. e7+ Kc7 30. e8=Q+.
|Oct-18-11|| ||voyager39: Just the kind of surprise Gelfand maybe preparing in his basement :)|
There are only two D05 games Anand has played, one he drew as white, this other one he lost badly as black.
