The number next to a member’s username is their chess rating!
If you’re new to chess, your rating probably started at 400 or 800, depending on what you selected for your skill level when you created your account.
Your rating goes up when you win games and goes down when you lose. We use your rating to match you with players of a similar level, so you get fair and fun games every time!
