Was this https://www.chess.com/member/ohno_mybotezgambits really Hikaru? Originally the member page showed "authorized speedrun account of Hikaru Nakamura all lost rating points will be returned". But now it just says closed for "fair play violation".
Since it was closed, it most likely was not a Speedrun account for Hikaru
I think it was Hans and his secret chess engine, the unexpected duo taking chess to a whole new level of "unfair play," as Hans brought his secret chess engine, but he must have forgotten to check the "fair play" box on the settings.
It was either Hans with his secret chess engine assistance or just Hikaru channeling his inner drama queen.
Whoever it was they were DAMN fast ....and precise. Smacked me down with a move 3 Botez gambit, then beat me on time and great defensive moves.
Wait how do you know? Did he say so on some stream?
It said on his member page as stated above. But could have been fibbing. Look at his/her results after playing all those Botez gambits
Oh wow. Nice! 
Sounds like a fun thing to do (play botez gambits and make a speedrun out of it)
