Watching pros play poker is often confusing. Some of their decisions seem strange, counterintuitive, and just plain wrong. This is especially true of Gus Hanson, who frequently makes plays that would seem clinically insane if it he didn’t consistently wins huge amounts of money. Watching him go all in with nothing in his hand and no draws leaves the viewer wondering “What was he thinking?”

He answers that question in his new book “Every Hand Revealed.” He gives a play by play analysis of what he did, and why he did it, for every hand he played in the Aussie Millions tournament, where he finished first and won a million and a half dollars.

He’s not embarrassed to discuss his mistakes in detail, or to admit that he did something because he just felt like it. He talks about when he was really thinking about his next move, and where he had already decided and was just putting on a show. He details the calculations he uses to make his decisions and talks about when to avoid coin flip hands and when they’re worth the risk. He shows how he increases his chip stack with rotten cards, especially when the antis come into play, and how he uses his stack size to push other players around.

Will it make you a better tournament poker player? Maybe. It’s not going to make you the next Gus Hanson, but it will show you how to use aggression creativity, the importance of stack size (both yours and your opponents) when making decisions, when to be aggressive and when to back off, and how unimportant the right cards can be in some situations. But even if it doesn’t dramatically improve your play, it’s a great read for moderate to advanced players.
