There is, amazingly, a game between two of the world's top chess grandmasters where both players used the bong cloud. The game resulted in a hilarious draw: https://www.chessgames.com/perl/chessgame?gid=2029671

Also, arguably one of the most famous bong clouds of all time came from Magnus Carlsen to win a blitz tournament last year against Wesley So: https://chess24.com/en/watch/live-tournaments/chess24-banter... . Carlsen turned a losing position into a stunning victory with a daring sacrifice.

I often play the bong cloud as a way to give a weaker opponent a handicap. It also works pretty well at psyching out a player who tries to stick to the book moves, but I've been consistently demolished when attempting the opening against anyone 1800+ on chess.com.
