Since a significant chunk of the EV in this game is from the top payouts (two Queen of Hearts - preferably with a dealer BJ), you also want to know the aggregate payout. For example, if the max bet is $25, but the per hand aggregate is $5,000, you're only going to get 200:1 rather than 1000:1 on the top payout. I would recommend placing a bet which is 1/1000 of the aggregate. The aggregate (or max payout) is usually posted at the table. If you don't see it there, ask.
