Battle Chess/Gameplay

Difficulty
When playing against a computer, there are ten difficulty levels within Battle Chess, which control the amount of time it spends thinking. On Novice difficulty, the AI only looks at immediate moves. On level 1, it will examine the board for up to 5 seconds, with each further level taking the double the amount of time from the previous one.

Since it is a fixed time, the computer will always be stronger on more powerful computers.

At any time, you can force the AI player to make a move. If you need to do this, you may consider reducing the difficulty.

Rules
The game supports all rules for the game of Chess, including castling, pawn promotion, and en passant capture.
