Does anyone else have that one dude in your class that is just an absolute beast and you can never imagine yourself ever coming close to beating?

There's this one dude that started training at my school within the last year or so. He's a purple belt with some stripes, and he's probably got around 50 lbs on me.

Usually I'd be able to at least hold my own against someone like this. I would't expect to win, but I'd at least expect to make it hard to tap me out.

However this one dude feels like I'm trying to fight a mountain. I literally can not budge this dude at all, and he effortlessly just destroys me from any position.

Even when he's inside my closed guard, he'll do some weird voodoo shit to tap me out.

If I want to go home feeling like I'm okay at BJJ, I'll roll with everyone at the open except this dude. But the instant I go against this dude, my soul is immediately destroyed.

Anyone else have "that guy" at your gym?
