Dealer get 17-20 points also quite high, $50 probability of losing is high. If dealer does not have a 10 card, $25 lose. Insurance choice is putting down extra $25 down on top of a $50 bet. Player has 3 choices, to hit, stand or insurance
I read from a book recently, it said probability of dealer having ACE busting is very low if the dealer can stand on soft 17. Because when dealer has ACE there is no option for players to surrender. I supposed you buy insurance at $25 when dealer has an ACE card while you have 15 points.
