For the life of me, I don't know why this poker book hasn't gotten much more attention than it has. In my opinion, the inaptly-named "Poker Tournament Formula" is as original and insightful as anything ever written by Sklansky, Harrington, or Brunson, and superior to 90% of what's on the market today. I know that it's not authored by one of the world-famous names in poker. I doubt we'll be seeing this fellow at a WPT final table any time soon. But pound for pound, this book packs a full heavyweight punch; there are at least a half-dozen brilliant original ideas here, and even when Snyder says what's already been said elsewhere, he says it better.
Honestly, for less than $15, I can't imagine what else you could want from a book. This is much more than some robotic "Poker Tournament Formula" (along the lines of the horrible "Kill Phil" system). The detailed discussion of tournament structure alone (complete with a reference website) is more than worth the price of admission. Snyder outlines in detail how to play intelligent, aggressive poker in the world of small buy-in events; quite frankly, if you don't play along the lines he recommends in these tournaments, then you simply are *not* going to win consistently.
Some have ridiculed the book for its comparison of poker to the game of "rock, paper, scissors", where chips are the rock, cards are the paper, and position is akin to the scissors. But in my opinion, this is the single greatest idea you could get out of this book: you don't necessarily need the cards to win a poker hand; you can win based on sheer chip arsenal or by outmaneuvering your opponents after the flop. It's true that these moves won't hardly work at all in a ring game against decent players (since there you *should* be playing cards and not chips or position nearly as much), but in fast tournaments this strategy is essential. This book will literally change the way you think about poker tournaments. In fact, I suspect it will actually change the way most of us view the game of poker itself.
I'd also recommend Poker Tips that Pay: Expert Strategy Guide for Winning No Limit Texas Hold em as a good compliment for "Poker Tournament Formula", with a lot more specific hand examples to study.
