As for the other question, yes, you can delete any game (non-tournament) within the first 2 moves, and it won't count for rating or statistics.

lukulus: Actually, white does have an advantage in Knight Fight due to starting the game. If black ends up unable to move, white will benefit from an extra move, which can mean up to an extra 99 points. Also because of starting, white always has first choice over which squares to delete. After several games that starts biasing the results a little in white's favor.
