Many years ago, there were 2 good friends. They used to play online Xiangqi together. Friend A is class A and friend B is class B.
One day, an opponent was playing with B and lost. Having admiration for B, the opponent asked B what is his result in Singapore. B replied "Champion in open tournament". A was very sour and started to badmouth everyone about B because B is a group B champion, rather than group A champion. A fight broke out when B realized A had been badmouthing B and they stopped talking to one another. Worst part is A influenced certain decision within the chess team and got B kicked out.
Morale of the story..... both are too mindful about reputation. If someone likes to say he is number 1 and says others are no class, let him be. If you engage him in a fight, you are stooping as low as him.
