Black Jack Ten Split Mathematics





















Green is beautiful, isn't it?


I got a request from "Joakim" to explain some mathematics behind the Black Jack basic strategy tips.

Let me start with the advice regarding never to split on tens. I will not show you the actual algorithm, since it depends on house rules as well as the number of decks, but you could reason like this - 20 is a rather safe hand. In most cases you will win on 20. Hence, splitting will take a safe hand and turn into into an unsafe one (or actually two). Even if you are Rain Man or even Mr Edward Thorp and count the cards perfectly, you will gain from standing on 20.
