Message: I recently completed a knight/queen checkmate. I wondered whether I could put it in the chess puzzles section -mate in so many moves. When I tried to enter it, the computer entered moves that showed that my checkmate could have been blocked.
Could someone with two computers set up a game as a puzzle on one computer and play it on the other computer - entering the moves on the "puzzle monitor) as they went along and so having the puzzle generate the best moves?
Should the Gameknot moves that check the puzzle be invisible?
I do not have any kind of chess engine so I think I will try to use it to play back my games and see where I could make improvements.
