I didn't know this, but Aditya Godhwani, a ~2500 level American player apparently has been training rather often in China for the last few years. He came into QSB for a match against Fang Yingchi recently. 2500 is obviously still quite a bit below QSB players' level, as even the ~2700 Zhou Xin went 0-fer against these former CNT players, but it's still interesting to see how real pros handle what would be the semi-pro level in the US.
