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.
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.
