Raymond cuelemans, 3 cushion & other disciplines. check the records. he dominated for so long, the format of tournament play was changed.
I've told this story before on AZB.
Back in the late 80's, we would have Willie Mosconi down a couple of times a year for exhibitions.
Willie came in the night before his exhibition. Willie, the owner of the poolroom and myself went to dinner. On the drive, I asked Willie who was the best pool player in the world.
He said "Besides me?" and started chuckling. Then he said "Seriously, the best player in the world doesn't even play pocket billiards. Raymond Cuelemans. He is a three cushion player from Belgium."
And that, my friends, was straight out of the horse's mouth.
As far as pocket billiards, I'd have to give Efren the edge over Willie in an all around.
