fukuhara: There is indeed a site that offers Chu Shogi, as well as Dai Shogi & Tenjiku Shogi ... http://www.gamerz.net/pbmserv
If you ever wish to play, my userid there is tkr101010 as well.

The game courier on Chess Variants also offers Chu Shogi, but the interface isn't as nice, http://play.chessvariants.org/pbm/index.html


I just want more sites to offer more variants :) BrainKing's got the nicest interface and plenty of people play shogi here anyway, so adding Chu seems logical.
