There are even sillier openings than what you showed and I might use anything if messing around, but if rated chess, then yeah there are many openings I'm probably not playing.
Stupid openings

The worst opening is the Bongcloud. But it was designed to be the worst, so probably should not count. If we disqualify troll openings and try to rank only "real openings", probably the Wayward Queen is the worst.
I agree with magipi, it seems sensible to discount any openings that are intentionally stupid.
Even the wayward queen is not listed in MCOs even as a eccentric sideline move and only seems to have become an opening in the past few decades.
The Damiano defence maybe. The fried liver as black.
For white you could say all kinds of unsound gambits like the halloween gambit or weak openings like the grob, but then again they might catch many unawares, so they could have a place.
I'll say the three knights. It's a historical opening so it's not some joke move like a3 or something, yet a very, very stupid move still. It doesn't offer any attacking chances and neither is it better at defence than just establishing your normal advantage as white. I challenge anyone to name a good reason to play 3. Nc3 that could not be answered better by playing a proper opening.
If you claime the Halloween being unsound then it should be interesting if you give me the refutation.
What do you think are the most stupid openings that you would never use? Thank you for your reply.
