 | | cu8sfan: Darn, <Dudley>. I think this is not the first time you beat me to get the honor of first kibitzer of the puzzle of the day... (-; |
|
| Dec-06-04 | | alexandrovm: Qe7+, with a double attack. But that was not the answer |
|
| Dec-06-04 | | alexandrovm: I think Qe7+ also wins the piece, hence black has to take the queen, and then the rook comes in with a double attack. |
|
| Dec-06-04 | | InfiniteWombat: I might have missed something, but if 19. Qe7+, then black responds with Rf7,
followed by 20. Qxf6 Kxf6 and the bishop escapes. |
|

 | | chessgames.com: We've got some tough problems lined up this week. Good luck! |
|
| Dec-06-04 | | Flyboy216: <alexandrovm: I think Qe7+ also wins the piece, hence black has to take the queen, and then the rook comes in with a double attack.> Why can't black follow with ♖f7 instead? |

| Dec-06-04 | | crafty: 19. ♕e7+ ♖f7 20. ♕e2 ♖d8 21. ♖xd8 ♕xd8 22. a4  (eval 0.55; depth 13 ply; 250M nodes) |
|
| Dec-06-04 | | Dudley: <cu8sfan> Incredible luck-and I even went into "long think" mode. The new puzzle comes on at midnight here in the Chicagoland area and I am a chronic insomniac. |
|
| Dec-06-04 | | Dudley: Or does it change at 11 pm? Lost track of time. |
|

| | cu8sfan: <Dudley> I get up at six, Middle European time. I think that's when the new puzzle is put on the web. Man, try and solve this puzzle is the first thing I do in the morning! I'm beyond hope... |
|
| Dec-06-04 | | Dudley: I would be to. Btw was not the finish of last year's pennet race one of the most incredible collapses in sports history? I'm not much of a baseball fan but I was for that one. I think Bartmann must have had to move, even though it could have happened to anybody. |
|
| Dec-06-04 | | pawntificator: Who provided the annotations for this game? Was it Blackburne himself? Criticizing his own play? heh heh. Anyways, yay me, I got this one. It was my first candidate move. I'm glad chessgames has some difficult ones for this week. Happy Holidays, one and all. |
|
| Dec-06-04 | | who: ok so whats wrong with 10 ... Bxd4 11. any with 11...Be5 Crafty? |
|
| Dec-06-04 | | cheski: <cu8sfan>: Coffee helps. Definitely. |
|
| Dec-06-04 | | Shams: Blackburne writes this on black`s fourth move: "He fails to take advantage of White's weak second move. c5 would have broken up the center to Black's advantage." Maybe c5 is better but white should play d5 in response and I hardly think black has an advantage!! |
|
| Dec-06-04 | | crafty: 10...♗xd4 11. ♖e1+ ♔f8 12. ♘fxd5 ♗xd5 13. ♘xd5 ♗xb2 14. ♖b1 (eval 0.56; depth 13 ply; 750M nodes) |
|
| Dec-06-04 | | Hektor: An excellent example of the poisoned pawn theme. Black seemed to be so preoccupied with regaining his pawn that he played 17. ...Qxd4. Perhaps he should have considered 17. ...Re8 to challenge the open e-file. Even down a pawn, black stood a good chance of obtaining an endgame draw (once the heavy pieces are traded) with his bishop vs. knight imbalance and pawns on both sides of the board. |
|

 | | mahmoudkubba: Black rock can try to check mate the white king, so if the white player is a weak player then black can win on him easily.. why resigning then (Black to Re8 after white move RxB and then he sees to resign or not?? |
|

 | | kevin86: <chessgames> it looks like we're getting no slack this week. It's coming around bowl time and if today is ny indication-I'm about to be flushed lol. |
|
| Dec-06-04 | | zb2cr: <mahmoudkubba>,
No, if 21 ... Re8; 22 Rxf7+, Kg1; 23 Rg7+, Kf8 (??);
23 Rdf7#. So instead of 23 ... Kf8, Black must play
23 ... Kh8. Then 24 Rge7 stops the mate, with a double
attack on the Rook and the Bishop, so Black still must
lose material. |
|
| Dec-06-04 | | Stonewaller2: I'd think the continuation would be 21. ... ♖f8 to meet 22. ♖xf7+? with 22. ... ♖xf7, but the simple 22. ♖xb7 bags the Black ♗. On 21. ... ♕xe7 22. ♖xe7+ ♔g8 23. ♖xb2 ♖e8 ( 23. ... ♖d8 24. ♖e7 ♖d2 25. ♖e2 ) 24. ♔f1. Resignation seems appropriate, especially so since Blackburne was by no accounts a "weak player!" Black doesn't have time for 22. ... ♖e8 or ... ♖d8 in light of ♖xf7+; on 22. ... ♕xe7 23. ♖xe7+ ♔g8 24. ♖e2 buttons up White's back ranks with his ♘c3 -- the move Blackburne thought was so rotten as a matter of fact -- and his ♔ will soon gain space. |

| | patzer2: <Stonewaller> Good analysis! After 21...Rf8 22. Rxb7  , Black is clearly lost. Today's puzzle solution with 19. Rd7+! combines the "pin" with the "double attack" tactic in the decisive followup 20. Qxf7+! Qxf7 21. Ree7! Note that 20. Rxf7+? Qxf7 21. Qd6 (21. Qe5+ Kg8 ; 21. Qe7 Rf8 ) 21...Re8! allows Black back in the game with near equality. |
|
| Dec-06-04 | | alexandrovm: right people, thanks for the correction :)
best wishes |
|
| Dec-07-04 | | Stonewaller2: My workout with CM8K last nite went 21. ... ♕xe7 22. ♖xe7+ ♔h6 23. ♖xb7 ♖d8 24. ♔f1! b5!? 25. ♖e7 b4 26. ♘a4 ♖d2 27. c3 bc 28. ♘xc3 ♖xb2 29. ♖xa7 ♖c2 30. ♖a3 ♔g5 31. ♖b3 ♔f6 32. a4 ♔e5 33. ♖a3. While the Black ♔ just managed to block White's a-passer the extra piece eventually provided the win. 24. ... ♖d2 seems worthy of serious consideration as well. Famous last words: "the win is a matter of technique;" there's sure a dance in the old dame yet here after ♖xb2. Not a position I'd resign as Black against an untitled player such as myself. ;) |
|
| Dec-08-04 | | who: Grandmaters don't always just resign or give up. even when the position is clear. In
Karpov vs Kasparov, 1990
Karpov refuses to accept a draw hoping the KASPAROV!!!??? will blunder his queen! See my analysis of move 76 |
