I know a player that took lessons from Bert when Bert was still in Chicago. He said the lesson were great but the time after the lesson were greater. He said Bert took him to places in Chicago that were unbelievable. They ran from PH to PH and bar to bar hustling games and meeting players that he would have never met. They drank, hustled pool and had a ball.
The lessons really helped this this guy and he says it was well worth the money. He is a Master player in the BCA
Things may have changed since Bert is a lot older.
