You will make money if you split 10-10 against the dealer’s 2, 3, 4, 5, 6, 7, 8, or 9. This reader is correct in that starting with a 10 is likely to lead to a good hand. I am likely to draw totals much better than the dealer will get when he starts with the worst of cards. I like the idea of starting two new hands with a single good card. Why should I not split 10-10 when the dealer shows 5? I like it because the answer to it is a good example of what this book is all about.

For example, when your expected win rate is -0.5%, you are expected to lose at the rate of 0.5%. What does matter is what the average outcome would be over thousands and thousands of such decisions.Ī positive expected win rate means that you are expected to win in the long run, and a negative expected win rate means that you will lose in the long run. Whether an action turns out to have been correct or incorrect on one isolated hand does not matter. This book assumes that decisions are made on the basis of expected value, also called expected win. Their purpose is to aid in understanding the importance of various rules options.
