Do you lose if you scratch in pool table on your brake?

No, you do not lose. When you scratch on the break, your opponent has ball in hand behind the head string. == If a player scratches on a legal break shot, (1) all balls pocketed remain pocketed (exception, the 8-ball: see rule 4.8), (2) it is a foul, (3) the table is open. Please Note: The incoming player has cue ball in hand behind the head string and may not shoot an object ball that is behind the head string, unless he first shoots the cue ball past the head string and causes the cue ball to come back behind the head string and hit the object ball."
