Simplify endgame factor for opposite colored bishops Stockfish is continually improving. Patches that gain elo in the past may no longer be needed as stockfish improved elsewhere. This patch removes passed pawns count dependence in opposite colored bishops scale factor. We used the mean of passed count pawns (~1.4) to compensate, and changed the base value from 16 to 22.
