Pick off play at 1B

[Adam]

This is a clear example of a clever genius finding a wicked loophole in the rules at a time when it's going to do him the most harm. I frankly can't imagine any scenario where I'd attempt a normal pick-off move if my wife was R1, let alone try some bush-league pick-off move.

Whether the move was legal or not, you should tell you Dad to admit he was wrong, apologize to your mom, buy her some flowers, and send an email to the entire family offering a forfeit.
