 | | cu8sfan: O boy, I saw the plan here but went for the ♗x♘ line. That makes it two days in a row that I didn't get the puzzle. Usually that doesn't happen on a Tuesday... It's gonna be a long week. )-: |
|
| Mar-15-05 | | ice lemon tea: i found both BxN n RxN...but still i feel that BxN is the better solution because in the end, white will have a more powerful combination of pieces (queen+rook) than the solution given (queen+bishop) |
|
| Mar-15-05 | | ashalpha: For anyone still looking at the BxN line please read peterk007's comments. They pretty much outline white's problems with winning against the dark squared bishop. It is far from clear with the rook forced to defend both the h7 pawn and the dark-squared pawn white pawn chain. There is also the to free black kingside black pawn which though not connected may cause problems. Does RxN cause any problems in the game continuation? |
|
| Mar-15-05 | | The beginner: I thought it was Bxf6 also.
It seems Bxf6 is also winning, just takes a lot more moves, but white is still a lot better than black after
36 Qxe5 .. fxe5
37 Ke2
The white king is much better positioned also the white rook is preventing blacks king from ever going to help his poor pawns against white's pawns. There is no way black can stop one of the white abc pawns from becoming a queen i think. |
|
| Mar-15-05 | | Valmy: I tried against a computer the B*N line. It looks like it works because the black king in g7 and the black pawn in f6 make Re5+ impossible (if Re5+ then Q*e5 and the black B can't take the Q because of his own king and pawn)Do I have something wrong? It possible, I am a patzer. |
|
| Mar-15-05 | | cjhasbrouck: Thank you <Honza Cervenka>. Kind of embarassed that I didn't have the foresight to figure that out. |
|
| Mar-15-05 | | Valmy: Oups, the f6 paws protecs the Te5. anyway the computer says mate in 10 after e8=Q... It's rated around elo 2000 so it could be wrong... |
|
| Mar-15-05 | | Reegan Milne: I probly didnt get the full effect out of this puzzle because i was too busy looking at the fact it was a game by ian rogers. For all those not in the know he is australia's greatest chess export. For all information on this champ try this link

| Mar-15-05 | | The beginner: PeterK007, and ashalpha
The problem for black after
..36 fxe5
37 Ke2
White is not really forced to defend the pawn on h7, as black cant pick it up.
If black take 37 Kxh7
Then 38 Rf7+ forking the black b pawn, and treatening to break trough with a,b, or c pawn. Blacks main problem after 36 fxe5 seems to be his pieces are all hindering each other movement. Black needs 2 moves to bring his Bishop into action. His king on g7, and pawn on e5 is preventing him from using the bishop before the white rook is finished clearing a path for a,b, or c pawn. |
|
| Mar-15-05 | | patzer2: The Queening combination starting with 33. Rxf6! is the solution to today's puzzle. White avoids the unnecessary complications in the line 33.Bxf6 exf6 34.e7 Rxg5 35.e8=Q Re5+, as given above by <Honza Cervenka>, when White loses the new Queen and Black with an extra pawn has counter chances in the Bishop versus Rook ending. White might still have a win there, but it is best to sidestep such difficulties. |
|
| Mar-15-05 | | white pawn: Could someone please help me understand the Alekhine Defense? I'm no expert by any means, but it doesn't seem like a good strategy to only develop a ♘, using up three moves. Is it so white over extends him/herself? |
|
| Mar-15-05 | | hintza: <white pawn> <Is it so white over extends him/herself?> That is the basic idea of Akekhine's Defence, yes. Despite Black's initial lag in development, the Alekhine's still remains pefectly sound. |
|
| Mar-15-05 | | white pawn: Where did black go wrong in this case? |
|
| Mar-15-05 | | kevin86: In the Alekhine,black's knight moves a lot-but he is compensated by the overextension of white's pawns. White must spend time finding defense for these pawns during which time black can develop himself and harass the pawns. My response to the BxN problem was that the king could retreat-but this is obviously wrong,so I stumbled into the Rook move-as it turned out-the right one. |
|
| Mar-15-05 | | Calculoso: Did not get "the" solution but saw 33. Nf7 Kxh7 34. Rh1+ Kg7 35. Rxh8 at which point white should be able to convert the extra material into a win. Of course this is not as winning as the text. |
|
| Mar-15-05 | | Marco65: In my opinion Black's position starts to become critical after 24...f6? 25.e6 and now 25...f5 seems forced, or it is White who plays 26.f5 locking in the black bishop. Unfortunately 25...f5 gives White the opportunity to create a dangerous passed h pawn. Black should have played 24...e6 and only then 25...f6. |
|
| Mar-15-05 | | euripides: <Marco> Black's problem is that the bishop is completely enclosed, so long as White protects f4. After 24...e6 Black would be effectively a piece down. |
|
| Mar-15-05 | | YouRang: Yay! I got another one - two in a row!
But I have to admit I didn't really consider the Bxf6 line, since Rxf6 seemed to be a clear Q promotion. |
|
| Mar-15-05 | | Shah Mat: you and me both cu8sfan |
|
| Mar-15-05 | | brainzugzwang: <The beginner> Yeah, Black has a positional weakness, but the h-pawn is about to fall unless White plays Rh1, and a sooner-rather-than-later e5-e4 sets the Black B loose to attack White's Q-side. It's difficult for Black to be sure, but it seems he can force White to work awfully hard to find a win. |
|
| Mar-15-05 | | yoozum: Yep, got this one too. |
|
| Mar-15-05 | | YouRang: <white pawn: Where did black go wrong in this case?>
I think Black is in bad shape coming out of the opening. Look at the board after move 15: [1] Black has moved one Knight 5 times. [2] Black has his dark square bishop trapped in a corner. [3] All of black's pieces are on the back rank (white has two advanced pieces). [4] White has a big lead in space (white pawns have advanced 13 squares from their original square, as opposed to just 2 squares advanced by black pawns). With this positional lead, white should be able to capitalize if he strikes quickly -- and that's just what he proceeds to do, particularly by taking advantage of the advanced pawns. |

 | | benveniste: I tried 33. Nf7, which also seems to be winning handily. |
|
| Mar-15-05 | | Milo: 5...g6 is somewhat unusual, as far as I know. The kingside fianchetto can be very powerful in the Alekhine (because of white's weak e5 and d4 pawns), but if white plays certain variations, there isn't really enough time. |
|
| Mar-17-05 | | ashalpha: Nf7 loses to Re4. Patzer2 is right, why go into complications when there is a complete win? If white does move with 37. Rh1 black does not have to take the pawn 37...e4 freeing the bishop diagonal suffices. |
