Can someone beat magnus carlsen the bot?

I beat the Magnus bot. Just play the Scotch gambit over and over until he hangs his queen. It's only a +1 advantage and he'll still press you. Actually drew the first time he did this.

True. A year ago I did this with two browser tabs lol. It's interesting to see how Magnus would beat Magnus. Also ran a few games between Magnus and Hikaru. I think Hikaru won as black once.
I beat it in 47 moves
