I like this game a lot
My suggestions mainly have to do with the draw mechanism. In this game, 25 moves sometimes just isn't enough, there's a lot of shuffling that you want to do to get your pawns or whatever in the right place. You should make it so that after 25 moves of inaction, the player has the OPTION to take a draw.
Also, your computer AI (even on "genius") is pretty stupid, but that's OK, the main problem is that it goes into infinite loops chasing one unit back and forth with another. Maybe that's a flaw in the structure of the game--that it is so prone to draws--but the AI could be programmed to detect a repeated sequence of moves and avoid repeating moves unless there is a big disadvantage if it doesn't repeat.
It's a pretty fun game, there are only 3 units worth much: pawns, kings, and queens. The other 3 units are only useful for killing pawns.
