The trick to making a jump shot draw is how you land the cue ball...
You have to land the cue ball exactly at the object ball or possibly one hop it, but it must be contacting the cloth and the object ball at contact time.... otherwise you'll get almost no draw out of the shot. Also, you have to hit slightly "lower" than you would for a no-draw jump shot of the same length with a bit of the same stroke you would use for a normal draw, but at the same time punch like a regular jump shot.... it becomes a total feel shot when you can do it... And don't expect to be able to do it if the object ball is over 4 feet away.
