How a New York Times bestselling author and New Yorker contributor parlayed a strong grasp of the science of human decision-making and a woeful ignorance of cards into a life-changing run as a professional poker player, under the wing of a legend of the game Maria Konnikova had never actually played poker before and didn't even know the rules when she approached Erik Seidel - Poker Hall of Fame inductee, winner of tens of millions of dollars in earnings - and asked him to be her mentor. She had faced a stretch of personal bad luck, and her reflections on the role of chance in her life had pointed her to poker as the ultimate master class in learning to distinguish what can be controlled and what can't. Seidel was in, and soon Konnikova was down the rabbit hole with him, a journey that would lead her to the following year's World Series of Poker.
