Or maybe there’s always a certain way you want to play a hand in Blackjack when you get two Kings? There are literally hundreds of rules of thumb that have been passed down from generation to generation without anyone really knowing where it came from or if it’s really true.

Here are some cool rules of thumb that I thought were quite interesting.
