The long stop shot. A very important shot in pool and also a good indication to you, the player, if your aiming is straight and if you can use draw properly. On top of that it also tests your speed control / judgement.
Don’t take a shot like this lightly, if you can master this, then shorter distances will be a piece of pie. The object is to have the cue-ball stop dead in it’s track when it makes contact with the object ball. That means no stun action in either direction, no draw action bringing the cue-ball back towards you and definetly no follow action which could potentially cause you to scratch.
