Jims,
I guess you are guilty of not memorizing all of my posts. The action at the Billiards Bullpen is plentiful because Mark will assign a spot that is fair for both players. See this thread for some details (down the first page):

I've seen one of the pro's match up against Donny the Destroyer (banger who does not try to pocket balls; rather he forcefully tries to get as many balls in motion as he can, hoping something will slop in - he is incredible to watch as his strategy is often quite successful) - get down 4-0 in a race to 5 at 9-ball; then come back to defeat Donny 5-4. Of course the pro was spotting the last 6 balls, but dang it was a great match.
Small stakes action was virtually continuous while I was there. To summarize; every player (any and all skill levels) that came in was willing to match up with either the pro or the spaz (me), sight unseen, using whatever spot Mark devised. I heard not one single negotiation of weight (just of amount or length of match). What a cool place; I can't wait to return.
P.S. - the lock artists around St. Louis will not get rich at Mark's place.
