The [[Draw|draw]] motive is a [[stalemate|stalemate]] threat, after the defending king blocks its own pawn after a queen check on the neighbouring knight file, so that the attacking king can't come closer.
A [[Distance|Chebyshev Distance]] of at least four to the [[Promotion Square|promotion square]] with a [[Manhattan-Distance|Manhattan distance]] less than eight for the attacking king is necessary to win that game (<span style="background-color: #c0ffc0;">green area below</span>).
However, there are positions where the attacking king may reduce the distance by due to [[Discovered Check|discovered check]].While implementing this pattern inside a [[Interior Node Recognizer|interior node recognizer]], one has to take care that with the king in the corner (i.e. black king on a1), the queen has no mate in one (i.e. on c1).
