Play online chess |  Subject: puzzle #5698
Message:
I have been looking through the different moves the Bishop could do in this puzzle and the next obviously only move the Knight would do in order to reach the mate. I was surprised that Nc7 as an alternative solution had been rejected as leading to more moves than the given solution. I look and relook at the board but can't understand why Nc7 would not be a mate within the two moves to mate. Could some of you more-experienced-players help me with that ?

Well 1. Nc7 Bxc7+ and if 2. Kxc7, we have stalemate (which is a draw, and not checkmate). Any other second move by white doesn't mate either, so 1. Nc7 doesn't deliver mate-in-2 (in fact, I don't think it even wins at all).

I think you want to add an alternative mating move, which isn't possible. I.e.
1. Ka6 Bh8
2. Nb6# or Nc7#
Both moves will be accepted when someone tries to solve the puzzle; but you cannot add an alternative to GK's automatic 2. Nb6#.

Vishy Anand and Magnus Carlsen lead the field for London Classic — Last year's London Classic at Olympia attracted large audiences, so its 2010 version on 8-15 December, with the reigning world chess champion Vishy Anand now in the field, will be of great interest. Its added spice is the rivalry at the top of the world chess rankings between Anand, Norway's 20-year-old Magnus Carlsen, and Russia's ex-champion and current world No4, Vlad Kramnik. The global chess body, Fide, still hopes to persuade Carlsen to rescind his withdrawal from the May 2011 candidates matches and has announced a new date of 22 December for contract signing. How he performs in London, just a week before the contract deadline, may affect the talks and whether he can take ...

Thank you ganstaman and heinzkat for your prompt responses.
heinzkat: I see. I came back on the refreshed board and the Bishop got on f3, when the Nc7 has been accepted. But... as I had been looking through your puzzle an hour ago, coming to the solution and hitting the returnbutton beneith the board to study the alternative solutions, I noticed that the Nc7 option hadn't been available. Shouldn't all possible solutions be in the Solutionlist on the right of the board?
PS: I like your puzzles heinzkat. Maybe one day I come through the twothousand and thanks to the given pratice might be prepared to offer you a nice game :)

The Man With Too Much Chess Talent — Dragoljub Velimirovic used to be one of the world's most feared attackers, always looking for the impossible. His imaginative play was compared to the colorful world chess champion Mikhail Tal's razzle-dazzle. His playing style was unique, daring and often falling off the edge. He made risky moves and so many of them that you wondered how much punishment his chess pieces could take. He loved to create confusion on the chessboard, always believing he could find a beautiful escape from a bad situation. He had enough talent to pull it off, perhaps "too much talent" as Bobby Fischer once put it when we discussed the play of the Serbian grandmaster and champion. At 68, Velimirovic doesn't seem to ...

i find it unusual that if there are two possible mates at the end of a puzzle, only one is listed in the possible moves. i guess it's because the puzzle maker here spots a mate in one immediately, records the first move it spots, then moves onto a different position. but all mate in one moves are accepted when solving, even if it isn't listed.

Chess: A sacrificial rook — Sacrificing a chess piece is a nerve-racking business, but think of the warm glow when it pays off. RB If chess pieces could talk, they would be screaming at me something like: "Can't you take a hint, dummy? We're all pointing in one direction – at c3!" And I would say back to them: "Yes, thank you, I see that, but I have to tell you that I am always nervous of sacrificing a chess piece when I can't calculate a forced mate or win of material." But let's try to get the nerves under control and venture the less valuable piece first: 1...Bxc3. What's to stop White playing 2 bxc3, and if 2...Qxc3 3 Bb3, with threats against f7? That doesn't seem to help Black much, so what about the rook: ...
