Smart Eyes of Poker: An awesome side effect

After numerous eye operations, Harry Owens is left with an intriguing side effect. It's not headaches, or nausea, or lightheadedness, it's the uncanny ability to see through paper the thickness of a playing card. What to do? Honestly, what would you do, gentle reader? Would it be morally, ethically, legally wrong to use what modern medicine built into your psyche? Harry has a dilemna....indeed, an awesome puzzle. To be able to see what card playing opponents are holding and what cards the dealer is tossing around a table is a breathtaking burden. Can Harry do it and keep his affliction under wraps? Should he use his new found powers or should he avoid the casino tables and remain a retired maintenance man who leads a humdrum existence of traveling aimlessly to the usual tourist spots? Seriously, what would you do?
