In shogi, King's Head Vanguard Pawn or King's Side Vanguard Pawn (玉頭位取り gyoku tō kuraidori) is a Static Rook opening. This opening utilizes a Boat castle in which the king (if played by Black) is positioned on 78 square. The pawn referred to then is the one on the seventh file that is originally at the head of the castled king (77). The term vanguard pawn (位取り kuraidori, literally "position taking") refers to a positioning of a pawn advanced to the middle rank supported by generals as a phalanx-like attacking formation.
