Murder is no game. Well, except for “The Most Dangerous Match,” wherein chess genius Laurence Harvey is terrified at the prospect of losing to someone even more genius-er than he is. Instead of just playing harder, he tries to kill his opponent by shoving him into what passes for early-70s green technology (a massive garbage crushing machine). When that doesn’t quite work, Columbo investigates the not-quite-yet-a-murder, trying to stay one move ahead of this Bobby Fisher analogue, putting his dreams of getting away with it in check. Appropriately, game designer Nathan Paoletta is the guest, helping Jon and RJ put the pieces in place. Games.
