probabilistic thinking tells the expert how to proceed: She is aware there’s a lot she can’t predict. But if she played this same hand one hundred times, she would probably end up $1,000 richer. So the expert makes the bet and stays in the game. She knows, from a probabilistic standpoint, it will pay off over time. It doesn’t matter that this hand is uncertain. What matters is committing to odds that pay off in the long run.
