Keep more pawns and pieces when attacking This patch increase the weight of pawns and pieces from 28 to 32 in the scaling formula we apply to the output of the NNUE pure eval. Increasing this gradient for pawns and pieces means that Stockfish will try a little harder to keep material when she has the advantage, and try a little bit harder to escape into an endgame when she is under pressure.
