Speed control, or cue ball control, is arguably the most challenging yet crucial aspect of high-level billiards, as it dictates the cue ball's final resting place and, consequently, your setup for the next shot. It's not just about pocketing the object ball; it's about placing the cue ball precisely where you need it for an optimal follow-up shot. The primary levers for speed control are the length of your backswing and the acceleration of your stroke. A shorter, more deliberate backswing with smooth acceleration will produce a softer shot, while a longer backswing with consistent acceleration generates more power. Avoid decelerating into the cue ball, as this leads to unpredictable results and a loss of control. Mastering speed control also involves understanding how different types of spin (draw, follow, stun) and contact points affect the cue ball's post-impact trajectory and speed. Constant practice through drills that challenge your ability to send the cue ball to specific locations on the table, ranging from rolling it just barely to a rail to precisely setting up combinations, is essential for developing this critical "feel" for the table.
