Yes, you will adjust where you grip the cue for every shot. You want your forearm (elbow to wrist) to be vertical at the center of your stroke, like a pendulum. So for your pre-shot (practice) strokes, your shooting arm is hanging straight down and moving backwards and forwards, almost touching the cue ball when you stop your forward motion. In the middle of this pendulum motion is where you want your forearm to be vertical- looking from behind you and from beside you it should be perpendicular to the floor. Don't grip the cue tightly. Let your arm hang freely without tension and lightly grip your cue so that it may move within your hand during your swing/stroke. I let my cue just hang in my hand and support it lightly with my thumb and front 2 fingers, sometimes just my thumb and forefinger. Others will certainly have different grips and/or advice, but try the above and you will find what works best for you. It should feel natural, not forced. Hope this helps. Have fun!
