Well, that a bit too much of code.

Checking for checkmate is relatively simple: You need to check whether legal draws exist that could take the kings place and all places around him.

Stalemate is similar with the exception that the kings place is not taken by the opponent.

I'd suggest that each piece has its own function whether it can take a certain field or not.

Adding to that, checkmate is made up of the following parts:
1. The king must be in check.
2. The king has no legal move.
3. The attacking piece(s) cannot be blocked or taken.
4. Time limit has not expired.
( 5. There is no stalemate (fairly obvious). )

For condition 3 you need to try every piece on the side being attacked and see whether it can be positioned to block the attack line.

Time is not a major consideration and is secondary to the other conditions. :)

Hmm, look at the attacking piece and it's line of attack to the king. Can any of your pieces move to somewhere on that line. If there is no such piece then it is checkmate according to that particular rule. Of course you have to check all the other conditions.

This condition doesn't apply to knights - they can't be blocked.
