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#.

Yemen sacks chess team for playing against Israel — Yemen has sacked the country's chess team and members of the governing body after its players competed against Israel at a chess tournament in Belarus. The Yemeni Sports minister, Hamud Mohammed Ubad, took the unusual decision after chess players ignored instructions to pull out if drawn against Israel, which is widely criticised in the Middle East for its policies towards the Palestinians. "This was an individual action contrary to the policy of Yemen, which refuses any normalisation with Israel," said Mr Ubad, adding that the chess players were on their way home from Minsk. Like several other Middle Eastern countries, Yemen does not have diplomatic relations with Israel and bars ...

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 :)

As Chess Olympiad Begins, No Surprises, but More Controversy — The first round of the Chess Olympiad in Khanty-Mansiysk, Russia, on Tuesday did not produce any upsets, though a few high-ranked chess teams yielded a draw or two. According to the Olympiad’s Web site, there are 1,300 players from 144 countries. The Chess Olympiad, which was first held in 1927 (or 1924, unofficially), is convened every two years. The 2010 Olympiad is particularly important as elections for the top offices in the World Chess Federation, the game’s governing body, will be held near the end of the competition. Prior to the start of the Olympiad, it had been plagued by problems, including a race to finish building the main venues before the teams arrived. Now that the chess event has ...

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 Puzzles: Richard Reti's Marvelous Squares — A chessboard is a square, divided into 64 black and white squares. But there are more squares in chess, mostly invisible, as part of an amazing chess geometry hidden in chess players' minds. One classic square is often used in pawn endgames when a king is chasing the enemy's passed pawn. The king doesn't have to walk in horizontal or vertical lines, he can run diagonally or zig-zag across the field. But he needs to be close enough to catch the pawn. How close? The king has to walk into a square whose one side is defined as the distance between the pawn and its promoting square at the edge of the board. We can use a famous study by Richard Reti as an example. The world-class player ...
