No Guard

No Guard (ノーガード nō gādo) is a variation of the Double Static Rook shogi opening, classified as a subvariation of the Double Wing Attack opening with mutually open bishop diagonals. The name "No Guard" originates from White's decision to forgo their defensive left gold development (...G-32) in favor of an early bishop trade, enabling a rapid attack with the bishop in hand. The absence of the defensive gold leaves White without a "guard". The opening is considered speculative since it is thought to favor Black and is not used by professional shogi players. However, it is tactical and quickly enters the endgame consequently being challenging to defend against successfully by some amateur players.
