Now lay the cue along the cradle that's formed naturally by your fingers. Your thumb acts as a support to keep the cue from falling. Make sure you do not squeeze your fingers too far upward as this will tighten your grip. There should be some daylight between the top of your, cue and the skin between your thumb and index finger. The cue is primarily held by your first two fingers and your thumb.
Some players also use the third finger.
Almost all the experts, however, agree that your little finger is not to be used in the grip, It may lie alongside the grip. Some players intentionally remove it from the cue altogether. Your thumb should be pointing nearly straight down at the ground and slightly inward. Where you place your grip hand on the cue depends both on your physical characteristics and the type of shot you are playing. Your first step is to locate the balance point.
