It takes a solid player to beat the ghost especially on a 9ft Diamond or similar table. I think I could push the 700 mark if I didn’t have a bad habit. However I’ll probably never even get closeHell, if any 650 is it going to give the ghost two balls on the wire, you can count on me to back the ghost.
Don‘t misunderstand me, a 650 is a damn good pool player, a level I’ll never reach, but still…
A good buddy of mine is a 669. 3,000 games established. We goof around and I take his money more often than not giving him 2/1 against the ghost.
