 ""Hold 'em Poker for Advanced Players"" (HEPFAP) was not Two Plus Two's first book. The first book Mason Malmuth published was ""Winning Concepts in Draw and Lowball"". It was self-published so whether it counts as a 2+2 book or not may be debatable. ""Gambling Theory and Other Topics"" was published one year before HEPFAP."
