I think about this one a lot. I'd say on any given night there is at least half the table that is strong and understand STT concepts/dynamics well, and then another segment is competent enough, but not consistently making deep runs. A few are, lets say, learning. I do wonder if it's a bit tougher of a game than people expect when they join up for the first time.
Not in that way, but I do have a 7-2 payout (first to show it and drag a pot), a donkey payout (first one out gets a $10 rebate), as well as $10 bounties on previous winners.
I have been thinking about a mystery bounty night too.
