use chess.uci to change stockfish skill level

Question

Our chess game project uses chess.uci and the stockfish engine. We used engine = chess.uci.popen_engine("/some_address/stockfish") to start an engine. However, I want to know if there is a way to change this engine's skill level. Could I achieve that by passing parameters to engine.go()? I saw there are options such as movetime and depth. Some Stack Overflow post says that there is a "skill level" option in stockfish but I didn't find it. What I want to achieve is to match the engine's skill to the player's skill. Thanks!

Answer 1

Have you read the documentation? It is all in there.

Here is an example from the documentation on how to limit the level given it a fixed amount of search time:

Playing

Example: Let Stockfish play against itself, 100 milliseconds per move.

import chess import chess.engine

engine = chess.engine.SimpleEngine.popen_uci("/usr/bin/stockfish")

board = chess.Board() while not board.is_game_over():
    result = engine.play(board, chess.engine.Limit(time=0.1))
    board.push(result.move)

engine.quit()
