A couple interesing percentages
Some interesting percentages in the game of blackjack... If a dealer has an Ace showing, about 31% of the time they will have a ten underneath. Only card counters should take insurance. And if that dealer doesn't have a ten underneath with that Ace showing, they have a 12% chance of busting. That's why what to changes so much with an Ace showing. If a dealer has a 5 or 6 showing, they have the best chance of busting, but it's still only 42%. Yes, you should still stand on your hard 12 or 13, but you're only going to win slightly more than 2 in 5 of those hands. But standing is still better than taking the chance you will bust.
