When I was in high school, the schools in the city had a puzzle master come to each school to entertain the students. The event at my school happened to be the day after the event at my nephew’s school. On the day he came to my nephew’s school, my nephew came home all excited to show off what he learned at the event. He said the man called the students up to the podium to solve riddles on a board. My nephew posed a puzzle. It was not a complex puzzle to solve, but it took some thinking, but we cracked it. The next day when the man came to our school, he posed the same to us. Of course, I recognized it, immediately ran up to the podium before anyone else could, and solved it – thus getting a prize! Would you say that I had an unfair advantage? What if I was a voracious reader of puzzles and had trained myself in solving riddles?
