According to the Vegas Values blog, these clubs are having a promo where you get a card and the dealer clips a spot for each BJ. Get 5, 10 or 20 and trade them in for a prize. Nice, but here is the kicker. Get a BJ the hand after one( in other words, 2 BJs in a row) and you win 10X your bet. I'd be upping my bets the next hand after a BJ if I were playing. Sure, it doesn't happen very often, but over a long weekend, it'll come up once or twice. Having a decent bet out will certainly up your trip income. A $5 BS player who ups his bet to $10 on the hand after a BJ should win a $100 bet about every 21 bets. That pretty much moves the game into the black, no?
