as sonny said. that game is not worth your time.....
I was half shoed at a game once in vegas, when i saw the cut card go in at 50%, i cashed out and left the casino, it was during a 2:1 BJ promo too. Instead of flat betting I was counting and ramping bets, because the pen was around 65% to start with. 2:1 is a huge edge, but not enough for me to max bet off the top. I was watching the other 4 people at the table get mauled, they were all max betting and all of them were digging for cash every few shoes.... ugly.
even 66% pen is pretty marginal - unless you are doing something other than counting. if i can't get 1.3 decks or BETTER cut off on 6D, I go somewhere else: another table, another dealer, another casino, or home!
