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#.

Previewing the world chess championship match — The world chess championship match between champion Viswanathan Anand of India and Veselin Topalov of Bulgaria begins Friday in Sofia, Bulgaria. The schedule calls for a rest day after every two days of play except that there will be an additional rest day May 9, between the 11th and 12th games. If the score reaches 6-6, the players will break the tie with a series of faster games May 12. Topalov, ranked second in the world at 2805, deserves to be considered a slight favorite over Anand, fourth at 2787. However, one can imagine almost any outcome. Anand has more experience in chess matches and he plays more soundly, with better judgment, but Topalov is more ...

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 :)

Final two rounds produce an exciting climax to the German chess league — Russia's national chess league may be the strongest in the world but Germany's Bundesliga runs it close and its media profile is far higher. The final two rounds last weekend began with Baden-Baden and Solingen on 24 points from 13 matches, Werder Bremen 23 and Mulheim 20. Baden-Baden is the cash-rich team and even boasts the world chess champion, Vishy Anand, and world No1, Magnus Carlsen in its squad, though the Indian has played only two games and the Norwegian none. But the active regulars are so strong that Michael Adams, the England No1, plays only on a mid-board in the eight-man team. Werder Bremen, which has links with the football club, fields ...

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.

Robot chess opponent — Hopefully Dennis who is playing with a a robotic arm as his chess opponent has not input the necessary code to have the arm reach over and choke the life out of him should he win the chess match. The Lynxmotion AL5A robotic arm is, after all, full well capable of plucking each chess piece and moving it to the next space. This is made possible thanks to a Python script Dennis himself created to process the moves and decide on the next move. A webcam is used to capture the location of the desired pieces on the chess board in order to help it in its task. ...
