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#.

A Match All About the Sicilian — An unusual chess match is being held in South Carolina. It pits Judit Polgar of Hungary, the strongest woman chess payer in history, who is now ranked No. 46 in the world, but once was in the top 10, against Gregory Kaidanov, a Ukrainian-born American grandmaster, who is ranked No. 261. The match is four games and has an interesting twist: Each game begins with a different variation of the Sicilian Defense. The first game was on Monday and was won by Kaidanov, who had White, and featured the Sveshnikov. The second, which was won by Polgar, was on Tuesday and was a Dragon. The third chess game, which is being played on Wednesday, and can ...

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 f-pawn, part 2: is f5 the answer here? — Does White have a better option than moving the f-pawn? Continuing our look at the chess equivalent of route one football – the f-pawn advance... RB Well, let's see what happens when we push – 1 f5. The answer comes back faster than Manchester United on the break, not much. Black is under no compulsion to take the pawn and can instead centralise with 1…Nd4 or even 1…Qd4, or start getting the queen's rook into play with 1…Rac8, and 1…Nb4, hitting the d-pawn, would be irritating. All right, let's try to be logical. What's wrong here is that even if we could swap off pawns on the f-file, the f1-rook would remain blocked by the bishop. Let's ...

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.

Big Surprises in Europe — Europe has been a center of chess activity over the last month with a series of major open tournaments. The first was the Gibtelecom Chess Festival in Gibraltar, which ran from Jan. 26 through Feb. 4. Among the world-class chess players who competed were Etienne Bacrot of France, Sergei Movsesian of Slovakia, Francisco Vallejo Pons of Spain, Michael Adams of England, and Gata Kamsky of the United States. The chess tournament ended in a nine-way tie for first, with Adams winning a four-person playoff to take the title. The Moscow Open, which overlapped with Gibtelecom and ended on Feb. 7, was divided into four sections — A, B, C and D — with ...
