>Wow, I've never played chess nearly that fast. The fastest I've played is like 30 seconds a move.<
it's 3 seconds increments - meaning that if a game is 5/3 - you have 5 minutes to complete the game, and one move can last upto the end's game. If you do make a move, however, 3 seconds are added to your clock. So if you make your first move in a second, your timer will be 5:02 - get it?
