Use a closed bridge (index finger looped around the cue) for power and precision; an open bridge (the cue resting in the V between thumb and index finger) is great for beginners and soft shots.
Your bridge hand usually sits 15–20 cm from the cue ball.
Press your hand firmly into the cloth and don't let your wrist lift.
Raise or lower your bridge to hit above or below center on the cue ball. Don't raise the butt of the cue.
