A little while ago, there was a thread about how players are separated into doubles and singles players. I never finished the thread and was unable to find it again. My conclusion was that: - if you were a more all-around player, you'd probably be a singles player. - the mentally stronger may be suited for singles, because doubles has a partner for mental support. - a good mover should probably play singles Then I thought, what separates a doubles player from a MIXED doubles player? I thought about it... I really didn't know. I knew that if a guy was good at the back/a girl was good at the net, they could play mixed with some success. Still... I think one of the best smashers in the game must be FU Haifeng but he's not playing mixed?
