To clarify on the 外援I had to step out and clarify something on the 外援 for team B. Actually, this is more of an internal training session for both teams. And since we are of the same club, there is not much of an issue of one team triumph over the other team. The main objective is to train. As for the 外援, he is brought in only because one of our member got something cropped up at the last minute and Guowei just happen to visit our club then (due to his urge to play more chess too?). So we are rather flexible and ask him to substitute the original player. He was not brought in to win. Please do not get the wrong idea. We were all happy with the results as all of us, (regardless team A or B, winning or losing) gained something out of it. Isn't that what Chess is all about?
