How To Use

Once you have your executable running, the main way to interact with the engine is through UCI commands:

1. [quit | exit]

• Terminates the program.

2. ucinewgame

• Shorthand for position startpos, which starts a new game.

3. position [<preset> | <fen_string>] [moves <move1> <move2> ...]

• Used to set the position to the given input.
• Presets include: startpos, trickypos, killerpos, and others.
• A <fen_string> can be used instead (without quotation marks).
• Then comes a list of moves to make after setting the position. The moves must be written in the form <start_square><end_square>.
• For example, a valid command could be: position startpos moves e2e4 e7e5 g1f3, which sets up the starting position and goes into the King's Knight Variation.

4. go depth <plies>

• Determines and returns the best move N plies (half-moves) into the future.

5. go perft <plies>

• Used for debugging and performance purposes. For each available move, it displays the number of possible game states N plies into the future.
