I recently read Ducy?: Exploits, Advice, and Ideas of the Renowned Strategist by David Sklansky. I got it for Christmas. It took me a while to read it. Typical of Sklansky there is a lot to think about so I read it a page or two at a time.
It was a good book. Not a poker book from Sklansky which was an adjustment. I enjoyed the stories from the Bob Stupak years in Las Vegas. There is a lot in there. It definitely makes you think, and that is a purpose of the book. The parts about a principled stand and being pragmatic were interesting. I liked the part about practical math and the importance and power of ratios and making an initial observation.
It was worth reading and I would recommend it. There's one more Sklansky book to go I would still like to read.
