The lag for break is the formal way to start a pool match. It is the way to fairly determine who gets to shoot first, and is something you will want to get good at, because it can give you an advantage over your opponent.

The player whose ball stops closest to the head rail wins the lag, and gets his choice of whether to shoot first or require his opponent to shoot first.
