checkmate analysis - 2006/12/31 03:43 Besides i am supposedly writeing an graphical user interface for chess tentatively using OpenGl. I admittedly need to also validate the moves of the players as the interface should be usable across a network.

On the whole the problem arises when i try to identify the cases when a checkmate or a stalemate position. While some may see it differently i have no better idea than computing all possible next moves & bodily finding that they are invalid. This is a too big a task to perform after every move.

on the other hand giving the user an option to claim checkmate or permanently draw seems too naive. Next is there a better algorithm to find this out.

thanks for anything from pointers to code ( in C or C++).

re:checkmate analysis - 2006/12/31 04:50 Why? It should bring only some microseconds for each steadily move, probably much fewer than needed to redraw the board, or what ever else you do in you GUI.
But it needs almost a chess-engine, to verify - sure. You'll need a move- generator, an "Incheck" routine, & a 1 ply search. But it won't take long..
