AI

This game supports three levels of chess AI which the level 3 is the most difficult one. The AI level can be changed through game option menu. The default level is 2.

Description of three AI levels:

1. AI makes a random move. Even though the move is randomly picked from all possible moves. However, the probability that the AI move attacks your (red) pieces is bigger than the probability that it doesn't.
2. Be careful, at this level, AI will try to attack your (red) General and defend black General as possible as it can.
3. For each piece, AI assigns it an appropriate point. And for all positions on the board, AI gives them different points, that the more important position has more bigger point. For all possible moves, AI evaluates each of them and picks the best move which has biggest point. Of course, the level 1 and 2 are still valid at this level.
