S&M are better writers? You must be joking. More comprehensive and better at explaining? That's another joke. "Part One: The First Two Cards" in HPFAP is quite bad. It doesnt explain their rationale for the hand groupings. It just gives you some groups and then says you might want to play this group or that group, it depends. No explaination as to why, the entire section is confusing. In Yao's book the starting card chapter is 10X better. Every concept explained in HPFAP is explained better in Weighing the Odds in Holdem. Its a much better book.
