Second nuts and getting in all in

[ImprovinNewbie]

no reads really on any of these guys and i would never have called an over bet on the flop but im getting something like 4-1 or 5-1 for nuts or second nuts and somebodies stack is going all in. the turn bet is huge. i have second nuts and there is no way i can even begin to think im beat correct, i mean the way the betting has gone....

You can't fold this.

I think you'll see two pair, some idiot with a lone A and sets enough times here to make the turn shove profitable.

I dunno if I would have completed this preflop though.
