Chuang is not good against defenders, if he meets Joo Se Hyuk it was his last match in this tournament. Otherwise his chances are not bad (against Boll 30% and Mizutani 50%)
Mizutani will not win, not very good against defenders (Joo) and 50/50 against Chuang and almost 0% winning rate against Timo Boll
I hope Boll will meet Joo in the Japan Open. Bolls statistic is very positive against Joo but Boll lost the 3 last occassions. Maybe Joo will play with the same equipment he used in the Hungarian Open to prepare again for London
