The drawing corner
0/18
The idea
A pawn on the a- or h-file cannot be won if the defending king reaches the corner in front of it: there is no way round the edge.
The corner is a fortress the pawn cannot pass.
- Head for the queening square of the rook's pawn.
- Once there, move between the corner and the square next to it.
- The attacker can only stalemate you or let you take the pawn.
