Bailing is key for keeping possession when there aren't good options to throw to upfield.
At stall 3 or 4, we should consider looking bail. Physically turn and face your bail handler. In this case, Handler 2 turns and faces Handler 1.
Handler 1 runs a bail. First bail is the Berkeley Cut. Upline at a 45 degree angle...
... and back if necessary. If Handler 1 receives the disc on their cut back, they have a roughly a 1 stall buffer to look and throw into the breakside...
So cutters upfield can react to this and make a breakside cut to move the disc further to the opposite side of the field.
Resetting the play for the second kind of bail (less advantageous but sometimes safer).
Handler 2 has turned and committed to Handler 1. Handler 1 makes a cut directly behind Handler 2 for a slight loss (but possession is retained, yay!) This can be referred to as a Jam Bail.
