I think the biggest comeback I've ever had was I was down to 20 chips or one BB against a player in a HU match on UB. He had 2980. I came back to win. He was folding from the button when I had about 60 or so left when I doubled up once twice. Probably the most insane comeback I've ever had! LOL!
But gj! Way to go! Congrats on your win.
