never play battleship against me, who ever heard of boats not moving when shot at?
Years ago, when my youngest was, well, young, she played Battleship with a friend of ours who came for a Shabbat meal. At some point, he said that her ship setup was impossible, because he had no more places to try. It turned out that she had been moving her ships around throughout the game.
She’s now 19, and we still remind her about that from time to time.
