Double or Die: Backgammon Is a Blood Sport for People Who Think in EV

Put down whatever image you're carrying of backgammon as the thing your grandparents kept in a leather case next to the good scotch. That version is real. It's just not the one that matters here. The version that matters is the one Wall Street traders keep in their heads without knowing it's backgammon they're thinking about: expected value, position sizing, leverage, the discipline to fold a bad position before it kills you and press a good one before the window closes. Edward Thorp, the man who beat blackjack, then beat the stock market, has a backgammon technique named after him. That's not a coincidence. DOUBLE OR DIE builds around one framework: T.R.A.D.E.: Track the race, Read the shape you're in, Attack with checker-play discipline, Double the cube like the leverage instrument it actually is, Execute the bear-off so a winning position stays a win. Every rule and every claim in these pages is checked against the current, computer-verified consensus, not 1976 clubroom folklore. This book will call you a degenerate if you play like one. It will also make you a better player than almost everyone you sit down across from. You already think in probabilities, or you wouldn't be reading this. Good. Set up the board.
