Yes, I also think recognition of Shatranj should suffice.
Also, based on feedback received here and in e-mail, Chaturanga support
will be removed from ChessV, since not only are the rules unclear, but the
present implementation is really just Shatranj with rotational symmetry and
lousy pawn-promotion rules. But, I will probably add support for the other
historical games described in Murray's text if they are described here, or
if I can find a copy in a local library.
