Once you get past worrying about which color you play, you'll start focusing on what really matters...how to play the color you get.
(Though, statistically, most players have a slightly better win ratio when they play white. But forget that I said this.)
How high must one's rating be for playing white to be a decided advantage? For some reason, I seem to have a better winning percentage when playing black. I guess I'm better at reacting than attacking.
