A combo of parameters tweaks This patch is a combinaison of two recent parameters tweaks which had failed narrowly (yellow) at long time control: • improvement in move ordering during search by softening the distinction between bad captures and good captures during move generation, leading to improved awareness of Stockfish of potential piece sacrifices (idea by Rahul Dsilva) • increase in the weight of pawns in the "initiative" part of the evaluation function. With this change Stockfish should have more incentive to exchange pawns when losing, and to keep pawns when winning.
