Yesterday's post, "Game of the Week," offered a claim that I had mastered a particular position with clear evidence in the same paragraph that I have not. This post aims to correct that error.
In a single pawn ending where one player's king stands on its starting square, or the adjacent square, with a a pawn in front of it, the opposing side's king may stand on any of thirteen squares and hold a draw. That is the case, if the stronger side is on the move.
If the weaker side is on the move, there are an additional fifteen squares on which the king may stand.
With White to move, Black draws with a king on any of the squares occupied by a Black king in the diagram below. With Black to move, Black draws if the king can reach any of these squares.
