HaChu is an AI engine for many variants of Shogi (japanese chess), and Chess.

It currently plays the following games: * Sho Shogi, the immediate ancestor of modern Shogi * Chu Shogi, the most widely played large-board variant (12x12 board), featuring the famous Lion piece * Mighty Lion (a simple variant of normal chess to more easily get to know the Lion; does not implement castling yet) * Dai Shogi, a variant on 15x15 board (no GUI support yet) * Tenjiku Shogi, a 16x16 variant with even more exotic pieces (unfinished, no GUI support yet) * More classical chess variants: * Shatranj (does not implement the baring rule yet) * Makruk (does not implement counting yet) * Standard Chess (without castling)

Most games (excluding Dai and Tenjiku) can be played through the XBoard GUI (version 4.8 and later).
