This is literally just a misplayed variation of the exchange alekhine
and if we’re talking weird opening names, nothing beats Die Konigspringerzuriickhaltungspolitik which is just german for ‘the bishop comes out before the knight’ iirc
edit: the Monkey’s Bum and the Thunderbunny Variation are up there too
This opening is literally called "Alekhine's Defense, Alekhine Variation":
So I guess Alexander Alekhine invented a way to play as white against his own opening for black? That's kinda strange. Anybody know the history of this one?
