I have tried it out a bit, and although I have no doubt that this will become great software, it still seems to be in a somewhat embrionic state at the moment. At least as far as the AI is concerned; I haven't tried the on-line capabilities.
For Chu Shogi at least the interactive diagram in the article at chessvariants.com
played significantly stronger. (Although still like an idiot by human standards. But I only tried it with sub-second thinking (against 30 sec for Ai Ai).) I never tried to play the larger Shogi variants against the diagram (which cannot do games with piece drops yet).
For those interested in a moderate-strength computer opponent in Tenjiku Shogi: there now is a Jocly implementation for that, at http://hgm.nubati.net/jocly/
. Jocly also plays mini-Shogi, Tori Shogi, Chu Shogi and regular Shogi there.
