Have you ever played the Frankenstein-Dracula variation? The Monkey’s Bum? The Nescafé Frappé Attack? These are all real chess openings, and each has some merit. That is more than can be said for the Bongcloud, which begins with the moves 1 e4 e5 2 Ke2.

This daft opening exploded in popularity last year when it was championed (in jest) by grandmaster and Twitch streamer Hikaru Nakamura.
