Introduce bad outpost penalty In some French games, Stockfish likes to bring the Knight to a bad outpost spot. This is evident in TCEC S18 Superfinal Game 63, where there is a Knight outpost on the queenside but is actually useless. Stockfish is effectively playing a piece down while holding ground against Leela's break on the kingside. This patch turns the +56 mg bonus for a Knight outpost into a -7 mg penalty if it satisfies the following conditions: * The outpost square is not on the CenterFiles (i.e. not on files C,D,E and F) * The knight is not attacking non pawn enemies. * The side where the outpost is located contains only few enemies, with a particular conditional_more_than_two() implementation Thank you to apospa...@gmail.com for bringing this to our attention and for providing insights.
