Philidor Position Practice: Hold the Draw

Watch the method: press play to see the winning idea run, or step through it move by move.

A rook down a pawn in a rook ending is one of the most common fates in chess, and one of the most drawable. The Philidor position is the reason why.

The fence. With your king in front of the pawn, park your rook on YOUR third rank (the attacker's sixth). This forbids the attacking king from stepping onto that rank to support its pawn: no king support, no progress. The attacker can shuffle for fifty moves; you shuffle back along the rank. The third rank is just the extreme case: the same fence holds a rank or two earlier too, which is why manuals always show it here.

The switch. Eventually the attacker's only try is pushing the pawn onto the fenced rank. That pawn move is your signal: the fence is obsolete, so the rook sprints to the far end of the board and starts checking from behind. With the pawn advanced, the king has no shelter from the checks: draw.

The classic failure is leaving the third rank one move early 'to be active'. Once the attacking king is centralised and its rook is active, the king camps on the sixth and the dead draw is gone. Here White's rook is still passive behind its pawn, so an early departure happens to survive; hold the rank anyway, because the habit is what saves you when the attacker's pieces are properly placed.
