There are three basic releases and they have to do with where the accumulator(s) begin to release along the delivery path of the hands: sweep (early as possible -- top of the delivery path); snap (as late as possible -- bottom of the delivery path) and random (somewhere in between).
To execute an automatic snap release, just keep driving the clubhead lag pressure straight at a pre-selected spot ("aiming point") along the delivery line, as though you were never going to release at all. When you get to the bottom of the delivery path, the release automatically happens. This one takes maximum courage.
