Easy I wasn't even trying

I believe at one point he said he's 1800 rapid because he's stronger than that but he just got bored of trying to get it up to his actual skills that he left it like that

I'm much better than 1800, why don't you play me then?

Of course you'll beat me in like 5 minutes won't you? I don't think much in rapid
