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: Karpov turns the screw — Karpov-Smyslov, Moscow 1972. White has come out of the opening with a certain spatial advantage. Now he has to find a plan. Warning: you're not looking for a sacrificial combination – this is Karpovian, it's all about subtlety and strategy. RB: I've nominated Karpov's Strategic Wins 1: The Making of a Champion by Tibor Karolyi (Quality Chess) for our book of the year award. It's a year-on-year account of Karpov's career from 1961 to 1985, nicely laid out and well annotated. Karpov's style is positional, unhurried and exceptionally deep. Constantly alert to the counter-stroke, he likes to make small improving moves. Some of Karpov's choices remain, even with the help of a chess computer, mysterious, as ...

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 :)

Winning in long run requires motivation — Chess is a worthy pursuit for all seasons of life; 6- and 7-year-olds can play a pretty good game. In recent years, chess players in their early teens have become grandmasters. And a 20-year-old, Magnus Carlsen, is the highest-rated chess player in the world. Meanwhile, 82-year-old Viktor Korchnoi is still capable of winning tournaments, though not at the same level as before. When do chess grandmasters reach their peak? The ballpark figure used to be 35. But two chess players in their early 40s — the champion, Viswanathan Anand; and the challenger, Boris Gelfand — will face off for the world title in the summer. Gelfand embraces the age factor. He sees no decline in his ...

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: European Players Are Well Paid for Team Play — The difference between the game in the United States and Europe is easy to illustrate by comparing two team competitions currently under way. The European Club Cup, which ends Sunday in Slovenia, features many of the world’s best chess players, among them Boris Gelfand, Peter Svidler, Teimour Radjabov and Ruslan Ponomariov. They have no particular loyalty to their chess clubs. They are playing because they are being paid, often quite well. And the clubs with the deepest pockets, like OSG Baden Baden in Germany and Tomsk-400 in Russia, are the only ones with a legitimate chance to win the chess tournament. Compare that to the setup of the United States Chess League, which just finished its fifth week of ...
