Rule Number One in gambling: the house always wins. Rule 1-A: Adam Kucharski can prove the first rule wrong. Which means you should probably not try to bring him into a casino with you.
Kucharski holds a doctorate in mathematics, and he reports on the success of systems like card counting (not allowed in casinos) that allow people to beat the house on a regular basis.
Science and a desire to win have combined on some notable gains, which are of some use to the world outside the gambling parlor, too.
Dr. Kucharski lays it all out in his book The Perfect Bet.
