I recently saw this play (not in an official casino, but essentially friends playing with themselves):
Dealer was dealt a 2 and an Ace. Being forced to hit, dealer was dealt a 10.
Player argued that it was a 23, therefore a bust (because Ace would be counted as 11).
Dealer argued that since Ace being equal to 11 would bust him, Ace cannot be 11 and therefore is 1, making his Hand 13, not 23.
Later on a judge decided that the hand was a bust because, and I quote:
The 2+Ace is 13. That's set. 13+10 = 23. What's confusing? once an ace is 11, it's 11.
I find it rather odd that he ruled like that, and I suspect something screwy going on, because (at least from my understanding of the rules) if the Ace were to bust him, Ace is valued as 1, not 11. Which is the right call here?
