Remove Condition For Passed Pawns Currently, we do not consider pawns passed if there is another pawn of the same color in front of them. It appears that this condition is not necessary. The idea is that the doubled pawns are likely to be weak and one of them will be likely captured anyway. On the other hand, if we do somehow manage to promote a pawn, then the pawn behind it becomes passed as well. In any case, the end result is we end up with an extra potentially passed pawn. The current evaluation for passed pawns already handles this case by also scaling down this effect.
