Hex Shogi 91 is an adapation of Shogi to a 91-space hexagonal board. It was created by Fergus Duniho. This preset will enforce the rules, spot check, checkmate, and stalemate, and automate captures and non-optional promotions. Please report any bugs to Fergus Duniho. As long as you don't make any illegal moves, bugs can be fixed without breaking your current game.
