The default number is 24, is that where I need to leave it for a hard game?
Use positive numbers for weaker opponents to bias Stockfish against positions ending in draw. Conversely, for stronger opponents, use negative numbers to bias Stockfish towards favoring draws to prevent losses.
Hi Jay! Is my understanding that, as of 2021, the Stockfish chess engine with the NNUE (Neural Network Unit Enhanced) evaluation function does not use the contempt setting. Instead, the NNUE function uses a neural network to evaluate positions, which does not rely on a contempt setting to adjust its evaluations.
