Longtime problem-poser Stan Wagon gives us plenty of Aha! moments as he shares his 10 most surprising problems. Baseball enthusiasts will also enjoy the double header in this issue. Tim Chartier, John Harris, and Kevin Hutson analyze how bad the situation was for the mighty Casey when he faced two strikes and no balls.
