\ Then pull back slowly, and just go forward on the same line you came back on.
- Ive been trying to practice this( the slow backward draw before "launch" and I found it helped a great deal with accuracy. the rest of what was said makes sense too. I posted before I read all the comments but it wasn't so far off, id just try to shot lighter at first.
aside from draw, this control of the backspin helps a lot if you are trying to use some top or bottom so you can place the CB after impact.
what I'm saying is that the height will cause draw, stop or follow but also somewhere in between. being able to sort of feather that technique in a controllable way is not only for backspin but also to control the speed and distance of the CB after impact.
gaining a fine control is very useful in placing the CB, because it gives you a lot of control of how far the CB "chases" the OB after impact. the speed of the cloth has lots to do with all that. how far down the table the CB goes or if it returns. often makes or breaks the ease of the next shot.
i as an rexample, if an opponent left a ball in the middle of the table, and I didn't want to sink it,, I may choose to try to hit the end rail and return the object ball to the head cushion so that takes the right weight. and also try to do it with the right speed and spin on the CB to park the CB at the bottom rail, leaving distance between.
Its a common shot in snooker. often you can get lucky and manage to get other balls between. then he has to shoot from the rail ( with no access to the bottom of the ball) at a ball on the opposite end rail with traffic between.
the object is often just to not allow a setup, even if its not a hook we hope the opponent cant; make the next shot so then he may miss or scratch or since he has a difficult shot he has has a harder time hooking the next player. if both balls are in the center of the table, on the rail, or near that, he maybe able to do a long bank but on a snooker table that's a 24 foot distance so it's not probable unless you are a real pro.
To get those two balls to both stop on opposite rails ,
its all about the shot speed and top or bottom spin combined, less about direction. often it amounts to a control of how much follow,
my point in that wasnt to change the subject , just to say that the amunt of backspin or foreward spin is important, not only to draw balls but to be able to place them both in some accurate way.
its not a stop shot and its not chasing or passing the OB, it is making the CB slow after impact and stop at the rail and meanwhile enough energy it he OB to go just barely to the other end.
- the object is just to create separation. more distance. if done accurately you can try to get a hook by getting some other ball between the two.
its common for opponents to keep doing this both trying to not allow any easy shot and hitting the same ball back and forth until one makes some error and leaves an open. with an open shot a good opponent can start running balls as he then can both make a ball and has some control over his subsequent cue ball position.
