Theme Lesson ELO Bracket: 1200-1399 (Intermediate) Archetype: Endgame ♟ 1 Positions • 8 Board Frames

Rook Pawn Drawing Exception

Core Lesson Objective: Understand why an a-pawn or h-pawn (Rook Pawn) is a draw if the defender reaches the corner square, regardless of king opposition.

Rook Pawn Drawing Exception

Position 1 / 1
Position 1/1 • Starting Position (White to Move)
Rook pawns (a or h pawns) are a draw if the defending king can reach the corner. Since there are no files beyond the board edge, White's king cannot outflank Black.

Mainline (5 Moves)

Move 1 / 5 1. Kb6

White plays Kb6, aiming to claim the promotion path.

Move 2 / 5 1... Kb8

Black plays Kb8. Shuffling back and forth between a8 and b8 is the key drawing technique.

Move 3 / 5 2. a7+

White checks with a7+.

Move 4 / 5 2... Ka8

Black retreats back into the corner with Ka8.

Move 5 / 5 3. Ka6

White plays Ka6, resulting in stalemate. The game is a draw.

Alternative Path Available — Consider: Played in the Game: a7?!

Alt Step 1 / 2 1. a7

White plays 1. a7, pushing the pawn immediately.

Alt Step 2 / 2 1... Kxa7

Black King captures the undefended pawn with 1... Kxa7, resulting in an immediate draw due to insufficient material.
