Insane double blunder by «Masters»

This game is in lichess’ opening book under «masters». Two top players both miss a hanging piece in the very opening.

My bet is that it was a prearranged draw and both players just blitzed a couple of alibi moves without really paying attention. 4...Bc5 wasn't really that good either and you would surely expect a 2500 player to still be in his prep at move 4 if he was playing seriously.

That or there was a mistake in the transcription of the notation. Or a combination of the two... alibi moves that the masters themselves did not care to notate properly.

Seems other sources report the same.





Perhaps it was prearranged. Who can say?
