Why did I win?

What was going on here?

The aliens!!

Lost connection on the other side

says right there:

Time out, White is victorious.

This is a well known opening. 3.Nf3 is winning by force.

Or maybe the bot crashed ?

Your opponent didn't know what to do against this amazing novelty!

It seems suspicious because this happened shortly after the bot sent out a forum post asking for someone to play it.

@Nicals
Isn't it 2.Nf3?

Magnus refuted the open sicilian here:

It's not playable for black anymore.

1. e4, c5 2. Nf3 is completely winning for white now.

The correct way to defend against 2.Nf3 is to make moves like h6, a6, e6, and g6.
