Originally posted by BowmannThe pure and only fact is that you have no proof to prove this absurd claim.
As White moves first, he therefore makes the first mistake. Essentially, since the winner is the player who makes the penultimate mistake, it can be shown mathematically that Black always wins. The proof, regrettably, is too long to post here.
I also have a better record as black. Besides playing style, it may also have to do with how you acquire your games-- if you don't pick up games as white and black in the same way, it could be that you tend to face slightly weaker players when playing as black.
Also, I imagine the advantage white gets from having the first move is much less signficant at relatively low levels of play.
