It also depends upon whether or not your goal is to win the most money, or merely to win the HAND. By never doubling and by adjusting your splitting strategy you could bump that win rate up to something in the neighborhood of 43.5%.
So that is to say you have a 51.8% chance of winning or breaking even. Which of course does not warrant going against a 48.2% chance of losing. It just goes to demonstrate why counters wait until the likelihood of better-paying naturals is highest, as well as the chances of winning on doubles and splits, before raising their bets.
Not sure flash1296, but according to our strategy engine the HE for 1D H17 DAS is .04 while its .66 for 6D with the same rules. So wouldnt you be more likely to win the first hand from the single deck game, since it has a lower HE?
