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 on the China road — Greetings from China! I am writing this column from my hotel room in Ningbo as I attend the 2011 World Team Chess Championship, which runs from July 16 to 26. Although I lived in Europe for four years (1988-92), this is my first trip to Asia. I feel privileged to witness the U.S. team as it battles hard against a tough field in an attempt to earn a medal and represent our nation on the world chess stage. I was invited to be a coach for the U.S. team, which is made up of three-time and reigning U.S. Chess Champion Gata Kamsky, 2006 U.S. Chess Champion Alex Onischuk, 2008 U.S. Chess Champion Yury Shulman, four-time U.S. Chess Champion Yasser Seirawan and 19-year-old chess phenom Grandmaster Robert Hess. A formidable ...

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 :)

Chess: Ulf Andersson, positional master — Andersson rarely makes a direct attack: he wins by subtle improvements in position. DK: I've been wanting to tackle positional play in this column for some time, but couldn't think of a good way into a topic that is just too vast – until inspiration came with the arrival of Grandmaster Chess Strategy, by Jurgen Kaufeld and Guido Kern (New In Chess, £19.95). The title is bland, but the strapline reveals the content: "What amateurs can learn from Ulf Andersson's positional masterpieces". Andersson is, for me, an enigmatic chess player: he rarely makes a direct attack on his opponent's king, preferring to exchange pieces and gently improve his position – and against strong chess players this frequently leads 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.

Bobby Fischer Against the World (movie review) — A riveting documentary about the troubled US chess champion and his battle with Boris Spassky. Liz Garbus's gripping documentary about the life and times of the troubled American chess genius Bobby Fischer asks a number of questions. Did Bobby's missing dad create an emotional void which was neurotically filled with chess? Is there something in the game that encourages immersive obsession and ultimate madness? Would Fischer have gone the same way if he had been a plumber or a welder? And why is it that antisemitism is the bigotry of choice for mentally ill people? Non-chessers like me are already basically aware of the second and third acts of this American life. The middle act was ...
