About Dai Shogi

A large-scale shogi variant with 29 piece types. No hand or drops — captured pieces are simply removed. Promotion is available within the far 5 ranks.
Simplifications: the Lion is implemented as a jump within 2 squares (omitting the historical double-capture/anti-repetition rules); the Horned Falcon and Soaring Eagle are simplified to move like the Dragon Horse/King (omitting their compound double-move). The starting layout is a best-effort reconstruction, not a citation-perfect historical replica.
