Vančura Position: Lateral 6th-Rank Defense vs Rook Pawn
Before a rook pawn reaches a7, station your Rook laterally on the f6 square (6th rank): harass the enemy King with side checks whenever it seeks shelter, and snap back to f6 to eye a6 whenever it retreats. Rook-pawn endgames break standard Philidor rules because the White Rook is trapped on a8—Vančura’s lateral f6 post solves this classic problem.
FEN: R7/6k1/P4r2/3K4/8/8/8/8 b - - 0 1 · Rf5+ Kc6 Rf6+ Kb7 Rf7+ Kb6 Rf6+
