 Chess and Other Board Games Discussion of chess and other board game strategy

 06-08-2012, 06:46 PM #1 old hand     Join Date: May 2007 Posts: 1,597 Tactics Problem White to move and win. Solution is in the spoiler. Spoiler: 1.d8=Q+ Kxd8 2.O-O-O! I came across this problem a while back on chess.com's tactics trainer. I thought about the position for quite a while and couldn't find a win for white. Surely the server is mistaken, I thought. When I gave up and saw the solution, I wanted to punch someone in the face. It's ridiculous (not impossible, but HIGHLY improbable) to think that the game could get to this point without white moving his king or rook. There was no hint with the problem to indicate that white still had the ability to castle, and given the situation on the board I think it's up to them to indicate white has that option. Sorry, just needed to rant. I hope I tricked some of you like happened to me

Really pretty one but for someone who's been tricked often enough doing puzzles, the 0-0-0 jumps out pretty hard at you when the king and rook are like are on their home square and there's no other pieces on the board.

So both might be ok I guess?

Correct, if this is to be an acceptable endgame study.

Re: Tactics Problem

think we've had enough spoilers, anyone who gets this far probably has figured out the theme of the problem.

Robert Timmer's Startling Castling! (not the only name this book has been published under) has an impressive 21 examples of this theme, including some games played by GMs and one by Max Euwe. The oldest example is Thornton-Boultbee, 1884:
