The Gambling Man

There's a tent in a traveling circus in the India. Inside this tent there's a man who is an expert in poker, you can recognize him because he always bets exactly 2 U.S. dollars and 31 cents. If you beat him after 3 rounds, he will bet his soul on the 4th round. Nobody has ever beaten this man on the 4th round, and if you lose well… You don't want to know.
