My backgammon coach, Zdenek Zizka, who happens to be 23 years old and the youngest grandmaster ever in the sport, recently played in the finals of the Backgammon World Championship in Monte Carlo. Hundreds of us watched from afar as he endured a rough match. There was a backgammon that was devastating, and for the last hour, the score remained at 17/3. Then he rallied to 19-8. And so on. He lost the match.
