Yes, I suppose these percentages only give a very shallow picture of the possible color-biases. That was why I included several games, but maybe Knight Fight should have been left out.

Come to think of it, I've had a few games where people would take the challenge, then cancel the game immediately after. Is it possible (maybe only for paying members) to cancel a game when you got the "wrong" color, and avoid having the game rated?
