|Oct-27-05|| ||snowie1: What a neat way to end that game; if K moves his R to a2, then black moves his R up the b file for immediate mate, or if he moves his R anywhere else, black's Rook follows and discovered check grabs the white R.|
|Oct-27-05|| ||dakgootje: imagine you are 15 years old...and you beat Anatoli Karpov
....wow...i would be very happy...and talk about nothing else...muahahah|
|Oct-27-05|| ||ReikiMaster: <shaikh123> if 97.Ra2 then Rb3+ is not mate as 98.Rb2 is a legal move - although hopeless unless black blunders with 98...Rxb2= stalemate! An impressive victory by possibly worlds most promising teenager!|
|Oct-27-05|| ||EmperorAtahualpa: WOW! Great move. All the other combinations indeed do lead to stalemate or 50-move draw. Great!|
|Oct-27-05|| ||Norman Glaides: What happens after Bc3?|
|Oct-27-05|| ||jahhaj: <Norman Glaides> 96...♗c3 97.♖xc3+! and White has a draw because 97...♔xc3 is stalemate|
|Oct-27-05|| ||Norman Glaides: Hah, brilliant.|
|Oct-27-05|| ||eaglewing: On move 93 Black protected his ♔ against checks from the side with ♗d4 and, I think, threatened a winning plan by moving the bishop to c5 to protect the pawn from there and freeing the 2nd row for checks against the white ♔a2. With follow up moves like ♗d4+/a2+ vs. ♔a1/b1 this should somehow give the win against passive defenses on 94 like ♖g6/d8. Nevertheless what do you think about it, do you see forcing lines?|
However, Karpov choose to actively attack the pawn with ♖g3, but what is the White idea against the other active defense, the attack option by returning with ♖a8?
94. ♖a8 ♔c4 95. ♖a4+ ♖b4 96. ♖a8
... ♗c5 97. ♖xa3 or
... ♖b2+ 97. ♔xa3 (or is this position without pawn won?) or
... ♗b2 97. ♖c8+ and it seems nothing is achieved.
Something else on move 96?
Maybe there is a another, better black move 94?
Is the position theoretically lost on move 93 or maybe before on moves 75/80/90? I feel it should be, but ♔a2 is surely the best defending position against a bishop bound at b2.
So what is the winning maneuvre?
|Oct-27-05|| ||eaglewing: Oh, and I forgot.
I'm not sure about 94. ♖a8 ♔c4. Maybe it allows directly 95. ♔xa3.
Therefore, is another winning plan needed against 94. ♖a8 than against 94. ♖g3?
|Oct-27-05|| ||Richard Taylor: I saw this fairly easily -but didn't Karpov have draw earlier?|
|Oct-27-05|| ||guy6051: doesn't look like anyone's going to win anything here.|
|Oct-27-05|| ||Richard Taylor: No - I was thinking he was in the other corner - K is lost bascially when he loses the piece I think.|
|Oct-27-05|| ||patzer2: <Dionyseus> Thanks for the research with the endgame table base from your post on a previous page. Needleman's 96...Kd5! is a clever endgame tactic, setting up a discovered check to win the White Rook. |
The swindle draw possibility after 96...Kb4? 97. Ra4+!+ = made the puzzle worth the time and effort to try and solve it.
Of course it is also a Zugzwang position in that White's Rook and King are safe so long as the Rook is not compelled to move off the a3 square. However, since White is compelled by the rules of Chess to move, having this initiative is now a curse instead of a blessing. For example if White tries to find sactuary near the King from the discovered check and attack on his Rook by moving near his King, then <96...Kd5> 97. Ra2 Rb3+ 98. Rb2 Bxb2+ leads to a quick finish.
|Oct-27-05|| ||buzzymind: Just maybe Iím getting my old playing strength back (I havenít played serious chess in 25 years but at the time I was 1800 rating, but 2000+ strength as I was young and improving). Iím not expecting to ever be as good as my grandfather (George Eastman, Michigan Champion 8 times), but I would like to be a solid 2000+ player with some hard work.|
I saw this quickly.
But, this is how I was thinking. If it were whiteís move, what would he do? As you can see white has no good move other than something like Rc3+! So, now that black must move, what situation can black create that would cause a situation close to if it were whites move? The really good move that stuck out was Kd5 as we need to watch out for possible stalemates. We should watch out for that possibility as we can see whiteís king is already in a stalemate position if he ever tries to sac the rook.
I didnít spend a whole lot of time on this, so forgive me if I missed something that should be mentioned.
|Oct-27-05|| ||awfulhangover: I must confess that I didn't find Kd5!! It's a very clever move.|
|Oct-27-05|| ||karik: Just wondering... This game (almost) is included in a Sep-21 kibitz by ConLaMismaMano in
The odd thing is that the beautiful ending is missing. How would anyone miss it?
|Oct-27-05|| ||YouRang: Got it. This is a very neat zugzwang! Immediately, one notices two important things: (1) the discovered check if the black rook moves -- allowing the black rook to capture anything in its vast range after the white king moves out of check, and (2) the danger of stalemate if the white rook can force itself to be captured.|
Once these two points are noted, the only thing that makes sense if for the black king to get out of the way! That leaves c5 or d5. The trick is to notice that 96...Kc5 is no good because of 97. Rc3+!
|Oct-27-05|| ||kevin86: Ex-champ bites the dust on a brilliant finale by black! The king retreat is the only move that avoids the stalemate!|
|Oct-27-05|| ||Queens Pawn: Dionyseus
What computer program do you use to calculate the solutions???
|Oct-27-05|| ||al wazir: (1) Did white have any advantage before the blunder 54. g5 (he had an extra pawn, but it was doubled, and the bishops were opposite)? (2) Does black have a theoretical win after taking the bishop with 56...Rxf5? Or should white have been able to draw?|
|Oct-27-05|| ||suenteus po 147: <iron maiden> This and all the puzzles this week should make good additions to your zugzwang collection.|
|Oct-27-05|| ||iron maiden: Thanks. I don't normally include endgame positions in the collection, but this one's cool enough to be an exception.|
|Oct-27-05|| ||snowie1: As ReikiMaster observed, it's not mate if white plays Ra2, but then when black takes the interposing R with his B, he now has the only material on board. Mate follows quickly.|
|Oct-27-05|| ||chesscrazy: nice game|
|Oct-27-05|| ||Richard Taylor: I will be honest - this is how I solved it -at first I thought it was too hard (I nearly left it out) as I know endgames can be very tricky so looked at discovered checks and also an attempt to get White mated so I tried (in my head) 96. ... Rg2+ 97. Kb1 Kb4 but Black cant get into a position to win by mate. I spent a bit of time on this - I was about to give up when I thought - what happens if he just leaves White? -maybe he is in Zuygawang? (the magic word!)|
So I tried 96. ...Kd5 and saw that it won as a check by White is met by a devastating discovered check and the rook has to get itself killed it can only go in two directions (!)
But Black still has to be wary of stalemate.
