Scale down eval for queen imbalance We lower the endgame value of the evaluation when we detect that there is only one queen left on the board (more precisely, we use a scale factor of 37/64, or about 0.58, for the endgame part of the evaluation). Hopefully this helps a little bit for the assessment of positions with queen imbalance, which are one of the well-known Stockfish weaknesses.
