Championship No-Limit & Pot-Limit Hold'Em is a book written by veteran poker players T. J. Cloutier and Tom McEvoy, both of which have won several World Series of Poker Bracelets in various events.
Championship No-Limit & Pot-Limit Hold'Em is probably one of the only texts that covers pot-limit hold'em, a variant of no-limit hold'em that restricts betting to the size of the pot and, in tournament settings, doesn't ever have antes.
While it's hard to judge the compare the content of the pot-limit sections to other texts just because of a lack of literature on the subject, the no limit sections aren't that great. Much of the book is spent with McEvoy saying "I'd do this, but Cloutier would do this" and vice versa. While it's good to present multiple viewpoints, it's not exactly confidence-inspiring. Some of the advice is regarded as simply incorrect in many situations.
The book really shines, for better or worse, in the last chapter, which is a collection of rambling anecdotes by T. J. about various strange happenings mostly while he was a road gambler. It's almost impossible to read these anecdotes without busting out laughing because of how odd they are and the way in which they are told. Stuff like "I used to play in this home game with a guy and everyone always said he was a mobster but I never saw it. Then he and his wife were murdered, the end." or "I was once waiting for a poker game and saw this other poker player come in and drop $30k on roulette in 5 minutes"
The actual usefulness of this book is negligible, however it may be worth owning simply because it's tantamount to a movie that's so bad it's good.
