Backward simplication On top of the usual conditions a) some opponent in front (but no lever) b) some neighbours (in front) (but no neighbour behind or same rank) c) < rank_5 to find out if a pawn is backward we look at the squares in front of this pawn to reach the same rank as the next neighbour. In current master, a pawn is backward if any of those squares is controlled by an enemy pawn on an adjacent file In this version, a pawn is ALSO backward if any of those squares is occupied by an enemy pawn.
