Tweak KingFlank when king is on edge files This tweak excludes files D and E from the KingFlank bitboard when our king is on the A or H files respectively. As far as I can tell, this affects two things: the calculation for CloseEnemies and PawnlessFlank. Aside from filtering out slightly less relevant attacks in the flank, I suspect this helps with king prophylaxis, avoiding attacks and moving towards the center when the pawns start to come off.
