I am a novice at Omaha/8, so I write from that perspective. I have Zee's book and Cloutier's book. Neither of them come close to offering the material Tenner and Krieger present in "Winning Omaha 8" for the beginning player. I think Zee and Cloutier believe you already know this stuff; Tenner and Krieger make no such supposition and start from scratch.
I am one of those players (and a pretty good one) coming from Hold 'em to Omaha/8. Over and over and over, Tenner and Krieger tell me Omaha/8 is NOT Hold 'em, and give example after example. They tell me to often muck pocket aces. What? Muck pocket aces? Yeah right! So I go to Zee's book and find one sentence: muck weak pocket aces. Tenner and Krieger devote a whole chapter to properly playing aces. Guess which book is more informative to the novice. Ever so slowly it dawns on me just how good their advice is. Ever so slowly I go from being a big loser to a small winner at the tables.
Over and over and over, they say Omaha/8 is a game of scoops, not of splits. For at least a month I think they are crazy. Why would I not play the nut high straight even if I had to split the pot? But they say it so often, it gets in my head like a song you can't get rid of. And I go from being a small winner to a much bigger winner.
The book is packed with facts. It has to be read, underlined, reread, reunderlined. I recall the chapter on Playing the Flop. I remember praying to God to please let this chapter come to an end. And yet it is the best chapter in the book, even if it has to be practically memorized word for word.
One small criticism. While the book is most certainly complete enough for the novice (and the intermediate and maybe even the expert who writes the other review and pans the book), it is missing a few paragraphs. It fails to say anything about playing Pot Limit Omaha/8. Maybe the casinos don't spread Pot Limit Omaha/8, I don't know. But the Internet poker sites most certainly do big time! I would have wanted even a little advice on how to adjust playing the game to pot limit.
I think this is the first book I've given 5 stars. I wrote this review in answer to those who criticized it. Please don't buy it if you might end up at my table.
UPDATE: Two and a half years have gone by since I wrote this review. The problem I mentioned then has enlarged greatly, that is, at least online, (practically) ONLY pot limit Omaha/8 is played. A book not containing a large description of the pot limit game offers almost nothing to its readers. I would very strongly suggest the authors update this book. Otherwise I would no longer recommend it.
