g15713: <"With a b-pawn or g-pawn, the situation is different as there is a new drawing zone. Assuming the defender cannot get his king in front of the pawn, he should move his king towards the comer diagonally opposite the pawn's promotion square. If the defender's king can reach this comer, the position may still be drawn even if the pawn is on the seventh rank.">
