Maria Konnikiva is the author of two New York Times best-sellers, The Confidence Game and Mastermind: How to Think Like Sherlock Holmes. She is now, also, a successful professional poker player. Her new book about her poker journey is called 'The Biggest Bluff: How I Learned to Pay Attention, Master Myself, and Win' is just out. Maria is my first 2-time guest. She and I talk about what the pressure and repetition and introspection (that one hones by playing high-stakes poker) do to sharpen personal judgment and how it can improve decision all-around making.
