Allow RQ through pieces. Bench: 3415326 (#2153) We evaluate defended and unsafe squares for a passed pawn push based on friendly and enemy rooks and queens on the passed pawn's file. Prior to this patch, we further required that these rooks and queens be able to directly attack the passed pawn. However, this restriction appears unnecessary and worth almost exactly 0 Elo at LTC. The simplified code allows rooks and queens to attack/defend the passed pawn through other pieces of either color.
