I have encountered this situation for the first time and I'm quite puzzeled. Don't understand what happened. I've been playing Banzai and there was this guy sitting on aprox 20 buy-ins and from one hand to another he insta rebought from 20 buy-ins to one buy in. I know that if I leave the table and I want to rejoin the software will place me in the same spot, if available, and with the same stack, you can't rathole in Banzai. So how did this guy do it?
