In shogi, the Duck or Duck Legs opening is a surprise Static Rook position characterized by a Duck castle and formation similar to a Double Wing Attack opening that transitions to a Twisting Rook-like position. It is typically used in a Double Static Rook game; however, there is a variation for playing against a Ranging Rook opponent.
The opening may be played by amateurs but is not used by professional players.
Essentially, the opening tries to trade the major pieces to get them in hand in order to drop them within the opponent's camp. Since the Duck castle is defends broadly against major piece drops, this situation can favor the Duck player. Failing the piece exchange, the Duck opening typically aims for an edge attack to break through their opponent's camp.
