My bad for modifying the original problem, the answer to which was "lift the king." It didn't say to set it down. Now that I look at it, I don't see that the king can be set down anywhere.
Which makes it a chess problem of the conceit type that doesn't occur in real life/games.
"Move White King One space up and one space to the left."
White CANNOT achieve checkmate in one move with this move because it blocks the rook (as Kevin pointed out in his first comment), and black could simply move forward and to (his) left to get out of check.
Mate is achieved as soon as the king is lifted. You don't even have to set it down (on c5).
ReplyDeleteBut the king will block the rook, so won't the black king be able to move to g5?

I'm pretty sure that White can pick up the King and move it Diagonally forward one space. CheckMate
ReplyDeletegbradley: no, that would allow the black king to capture the white king, meaning white loses.
ReplyDeleteI would like to know how this can be accomplished in "less than one move"?
ReplyDeleteWouldn't you need to at least move once to accomplish the mate?
Maybe you didn't understand?
ReplyDeleteMove White King One space up and one space to the left. Of course he can't move diagonally to the right.

Got it,
ReplyDeleteYes it will take more than one move, but He's eventually toast.
This seems to me a good idea- but botched in this example, because several king moves fail to mate.
ReplyDeleteWell, white queen for steps to the right - but it would require one move.
ReplyDeleteSorry, Tonio; that would only result in a stalemate. (Blowing a great lead...)
