have seen him showing river that way befoer

He is fish becasue not full stacked in some hands.

So what in my head: I have best hand fop tunr and river and he shoves. WHat is that? Is this 7, or set or 2 pair or bluff with busded drwaw. Really hated folding but thouth that they dont turn into bluffs for such big sizes too often
