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#.

Chess: How to play like a world champion — The latest study of Vishy Anand concentrates on the world chess champion's outstanding strategic judgment. We'd all like to play like a world chess champion. So what's Vishy Anand doing that's so special? Last week we highlighted his depth of calculation, this week we focus on his strategic judgment. RB: I have no idea what to do here. I have no idea if Black is better or worse and I have no idea what Black's plan might be. Is the white queen trappable? It certainly looks locked in, but without a light-squared bishop it's hard to see how to exploit this. Is there anything in 1...Nc5...? No, apart from a lost piece. Opening the a-file with 1...axb4 might be an option, but ...

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 :)

One Coach, Many Young Chess Champions — In the last five years, two Americans have won world youth chess championships: Daniel Naroditsky, who took the under-12 title in 2007, and Steven Zierk, the under-18 champion last year. Both are from Northern California, and at one point or another, they both had the same coach, Michael Aigner. They are not the only chess champions who have been trained by Aigner. Others include Gregory Young, who tied for first in the 2008 United States Junior Championship, and Yian Liou, who tied for first in the United States Cadet Championship (for players under 16) last year. He has also coached Saratoga High School to six straight California chess titles. Aigner, 36, is a master, and ...

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.

Solving Bobby Fischer (book review) — In the summer of 1972, the world’s attention was directed toward Reykjavik, the capital of Iceland, to watch a championship chess match. Called “the Match of the Century,” the contest between the Russian chess champion, Boris Spassky, and the American challenger, Bobby Fischer, attracted that attention because of its cold war implications. But people were also fascinated by the mercurial Fischer — a prototypical genius whose incessant demands and unpredictability were more associated with the behavior of a diva than with what one expects from a master of a demanding game of logic. Fischer won the chess match in brilliant style, setting off a wave of enthusiasm for ...
