A similar draw motive occurs here with [[stalemate|stalemate]] after the queen captured the bishop pawn.
The winning area of the attacking king requires a bit more calculation.
Critical squares for the [[Distance|Chebyshev Distance]] are on the same rank on the [[Pawn Spans|luff-side ]] two squares apart (i.e. for black pawn on c2, [[Distance|ϑ(♔,e2)]]),and the diagonal neighbouring square on the [[Pawn Spans|lee-side ]] one rank back (i.e. for black pawn on c2, [[Distance|ϑ(♔,b3)]]).

* Attacking king may reduce distance by [[Discovered Check|discovered check]]
* With a <span style="background-color: #c0ffc0;">distance below two</span> to any of these critical squares, the game is won.
* <span id="rule3"></span>A <span style="background-color: #cc80cc;">distance of two</span> to any of these critical squares is not sufficient, if the defending king occupies is on the [[Pawn Spans|lee-side]], corner square (i.e. a1), or the 7th/8th (1st/2nd) rank on the neighbouring knight file (i.e. b1, b2).
* Exception: attacking king can immediately capture pawn
