This is not a usual chess game. You can make your own rules. You want a 12x12 chess board and two queens per team? No problem. The integrated a.i. will learn the new situation.

Features are nice graphic (textured blender created models), several game modes, several a.i. levels, flexible rules, described in xml files, flexible board, start configuration, figures etc. decribed in xml files, object oriented open source code, flexible code.
