It's a very aggressive play. I don't think I'd have the juevos to do it but he was probably playing the stack. You have to accumulate chips from the donks before they are all gone but I gues it was dependant on his reads. It looks like he didn't mind being all in vs. the smaller stack and figured the other guy for a low to mid pocket pair? Lokks like he's just slinging chips around to me though.
