That's interesting. Maxim in Vegas years ago had a single deck game with good rules plus late surrender. It was slightly positive off the top and it was pre Rule of Six days so depending on the dealer they went well beyond 50% pen once in a while. They ran out of cards twice one night when I was playing there. There was another casino out near Henderson that had a game that I believe was slightly positive off the top also. There was an airplane hanging from the ceiling in one of the restaurants and it was a nice, good sized place but I just can't remember the name. One table, a card counter at every seat every time I was there. I walked in there one day and there were two guys from my home area on the game.
You could jump from table minimum to table maximum. We may have crossed paths.
