from the game played xuyinchuan v.s zhou shi jie, i personally feel zhou shi jie did not play very well and xuyinchuan made lots of rough moves. i asked xu myself and he himself said that zhoushijie had lots of chances. Becaused xu had gave zhou shi jie coaching lessons b4 so i believe probably knew zhou's style of play better and he also had to win due to the team's situation. Move 74, black moved che 2 ping 5. if black move che 2 ping 6 red has no chance of winning infact i feel black is alittle better. Black che 2 6 ,red ma4-5, black che6 5, red che 3ping 6, black shi 5+ 4, red che 6-2, black ma 1+2 black is at slight advantage. Furthermore, Black's 76 move is the killer move for the whole game. He should move shi 5 + 4 instead of shi 5 + 6 the game can still be played.

From zhao ru quan's game versus sun yong zheng, move 37 zhao ru quan should move pao 7 ping 8 instead of pao 7 tui 2 black probably would move che 3 ping 2 or pao 1 ping 2, if che 3 ping 2, red pao 7 ping 4 red is at advantage. If pao 1 ping 2, red che 5 ping 8 exchange pao, red is also at advantage.

Xiejing's game, move 59 red should not che 8 + 2 and should pao 9 ping 5, red probably has a few variations but in all red still is at big advantage. pao 9 ping 5, black pao 3 + 7, red Shi 6+ 5, black che 1 tui 6, red che 8 - 1 red is at advantage.
