I read the author's earlier work on how people get conned, and this looked interesting. It was, very much. I still don't really understand much about poker, but hardcore poker people would probably really like this. Konnikova set out to see how poker could help her make decisions in other areas of her life, and I found it useful in the same way. As a statistics nerd, I could relate to her approach. Fans of this might look into How Not to be Wrong, by Jordan Ellenberg, but if I remember correctly, you need to be even more of a math geek to get as much out of that book.
