my personal view only .......
******************************
those plan to join and having chances in Top 8 of Group B can approach SIXGA on this matter .......
anyway, if 2010年6月6日 is the last round of 7+3 system, i.e. Round 10 for 象棋个人赛, then only the Top 8 players of Group B are affected if they join CFA杯 too as Group A is having 7+2 system so far and the last round of Group A should be on 2010年6月5日.
