Chess is a game so complex that even with all our computing power it remains unsolved, which means that the perfect strategy has yet to be determined. And that’s just boring old regular chess. It gets considerably more complicated when you and your opponent can use time travel to send your chess pieces into the past and create different parallel universes. Now thinking ahead isn’t enough—you have to start thinking a few dozen moves behind and a whole bunch of moves sideways.

I’ve played one game of 5D Chess With Multiverse Time Travel, but that means I’ve really played several games of 5D Chess With Multiverse Time Travel, because of the new timelines that spring up when you send chess pieces into the past and thus create new timelines in a parallel universe, you’re constantly playing a number of slightly different games of chess at once.
