Isn't this the same as Losing Chess
Blunder Chess.
Actually, no. Antichess/Losing Chess is to where you must force your opponent to take all your pieces first. Blunder chess is to where you must make the worst moves possible no matter how they are.
Tip: A good way to end the game is when you and your opponent are tired of it, you can ask a draw and then end the game that way. Or just play live with 3 minutes, 5 minutes, ETC.
In your variant, I'll play very good moves and claim they're very bad moves. I see a definition problem here.
whoever has the lowest accuracy wins
Or the other way, who ever has the most mistakes/missed wins will win.
Same thing unless you tell the person you're doing this. The steps are to challenge a friend who knows you are playing this variant, make it unrated, and make sure he knows the rules as well.
