BY FAR, having the good fortune of becoming friends with a couple of stout 3-cushion players who know how to apply their billiard knowledge to the pool table. The very first thing one of these guys taught me was a super simple off table system that completely removes all the guess work from multi rail position play... Simply blew my mind right from the start.
If you want to improve your position play in a hurry, try and get some good billiard players to teach you a thing or two.
Of course, a good straight repeatable stroke predicates the effectiveness of anything you learn.
Sounds interesting. Would you be willing to share this with us?
