now follows a list of books, so you can start your studies in poker.
1 - Power Hold’em – Daniel Negreanu
2 - Harrington no Hold’em - Dan Harrington
3 - Kill Phil - Blair Rodman, Lee Nelson, Steven Heston
4 - The Theory of Poker – David Sklansky
5 - Small Stakes Hold’em – Ed Miller, David Sklansky, Mason Malmuth
Cool list; I've heard some good things, but the only book I've read in this list is Power Hold' em - Daniel Negreanu.
I think it depends on what you would like to get out of your reading "study" and what level your game of poker is at; I'd recommend a different book to someone learning the rules of poker compared to a professional high stakes poker player
For instance, the Negreanu book mentioned is a great book, but his "small ball" is surely a strategy geared more for the advanced player with post-flop ability (and perhaps good hand reading skills too).
For a complete beginner, I'd recommend "Play Poker Like The Pros" (Hellmuth) and for the more advanced, I'd recommend some other books. "Excelling At No Limit Hold 'em" (Little) is one such book that is great, but more for advanced players (doesn't need to be professional or anything, but at least someone willing to put in the work and doesn't mind navigating range charts and similar).
Whatever book(s) to go with, good luck with the poker journey
