Finally, a tiny benefit from splits (since they happen so rarely) and surrendering truly crappy hands. More with appropriate hard doubles, and smart soft hand plays.
More with standing with 12-16 v 2-6 to avoid the aforementioned Mutual Bust.
We get some of it back with blackjack paying 150% about every 21 hands. With dealer rules, he busts about 27% of the time and if a player used the same rules, there would be a mutual bust 7.5% of the time! (27%)x(27%) Definitely a huge losing strategy. Yes, the house edge comes from the fact that the player goes first and a mutual bust is a LOSS for the player.
With all due respect, this is a forum for APs who are able to achieve a long term advantage in Blackjack.
