Yamato and I have independently started development of Zen and FudoGo 
(resp) with sharing the same idea*, combining MoGo's sequence-like 
simulation policy and CrazyStone's larger patterns, though later Zen 
uses more complicated policy.

*This is one of the reasons I have started the joint project "DeepZen" 
with Yamato.
