In the monthly CBJN there is an "edge" column. What assumptions are made to come up with this? Is some sort of bet variation/count strategy assumed? I would think so, otherwise, a DD game with just S17, ds with a .19 edge, couldn't be as good a game as a 6-deck shoe that has S17,ds,ls, and rsa with a .26 edge.
Anecdotally, my results on my annual wedkend trip were TREMENDOUSLY better at DD than the shoe. So many more very good or very bad count situations arose in DD where you can act - raise your bet and/or play two hands when its good, or pretend to have to take a phone call on your cell phone when its bad - that DD was much more rewarding for me than the shoe. Without using a count system, I'd think being able to surrender and resplit aces would make the shoe a better game for the basic strategy player.
