A two-session matchpoint event at a regional tournament, How to gather information from the auction, play of the cards, the atmosphere at the table, when to go against the field.
Maybe the best (and certainly the most enjoyable) duplicate bridge book I've ever read, and I've read a lot of them. Mike Lawrence's books are consistently excellent, and this one combines an interesting story line, as we bid and play every hand with Mike in a two session pairs event, with Mike's advice and observations about technical bridge, reading your opponents, and maximizing your match points. And it's all leavened with a good-humored, modest writing style. Highly recommended for players of all levels.
