Since I saw you are online, I am curious to know if you know the answer to this question:
What is the % chance of winning if you eliminate blackjack like being dealt AJ is just simply 21. And excluding blackjack payout of 3:2, what is the Expected return or house edge? Always wondered this since right away you know you lose some value when you are not dealt a blackjack.
Depending on the other rules and whether the player makes the appropriate adjustments to Basic Strategy, it adds about 2.27% to the house edge.
You can see the effects of many rule variations here:
