The bridge rank

0/15

The idea

With your king in front of the pawn on the eighth rank and the enemy king cut off, bring your rook to the fourth rank: it will block the checks, a bridge for your king.

A rook on the fourth rank as a bridge over the river of checks.

  1. Cut the defending king off by a file with a check (Rd1+ for example).
  2. Lift the rook to the fourth rank (Rd4): this is the bridge.
  3. Walk the king out from in front of the pawn; when the checks come, approach the rook.
  4. Block the last check with the rook on the fourth rank; the pawn queens.
