What is the Bongcloud opening? I have heard the Bongcloud opening mentioned on chess.com, but I have never heard of that. Is this a real opening, and if so, what is it?
The Bong-Cloud opening is a joke opening that is meant to give your opponent a chance, and also it is meant to show contempt for your opponent. You play it because you think you are much stronger than they are. It is, obviously, not a good opening.
GM Hikaru Nakamura is one of the jokesters, who plays this from time to time. There are multiple YouTube videos showing him playing this. Here is one.
P.S. Another chess.com joke you might hear is a reference to the the &quot;Botez Gambit&quot;. It is a joke about WFM Alexandra Botez, who drops her queen a lot.
