Rook vs Pawn: Outflanking the Blocking King

White to play and win

Play

Your king stands behind the pawn and the enemy king blocks the road straight ahead. Shoving him back does nothing here: one rank lower, that very push runs into a knight underpromotion and only draws. The winning idea is to go around. Outflank the blockader and meet the pawn from in front.

Outflanking From Behind the Pawn

The theory

Against most passed pawns you cannot simply shove the defending king backwards: he underpromotes to a knight and draws. When your king starts behind the pawn, the answer is to walk around it.

Why not push. One rank lower, the direct push straight down the board runs into the knight promotion trick. Outflanking sidesteps it entirely by bringing your king to the far side of the pawn.

The detour. A rook check makes the defender choose a square, and then the king circles the queenside, Kc6-Kb5-Kb4, gaining ground the blockader cannot contest. When the pawn runs to c2, the rook drops behind with Rc5 and the king takes it.

In this drill the defender is tied to his pawn and will push it as fast as he can. Check once, march the king around, and arrive in front of the pawn in time.
