I don't know who the best player for fun is (probably Eufema or Hohmann), but Jeff White plays some pretty good pool for fun. He was nice enough to shoot some games with me a couple of years ago, I was about a C player at that time. He spent most of the time at the table, running rack after rack. He ran out every time I missed (which was a lot). But the best part is he never stopped talking. Telling stories about different pros (Steve Davis, Earl Strickland). I was incredibly impressed that he could play at such a high level, with no incentive while seemingly distracted.
