Hi guys, this is a hand not played by me (since I don't play MTT): it is a Christmas donkament with 15 € buy-in, so the field is supposed to be pretty soft on average.

We are 350x at 25/50: it is one of the first hands, so we have no info on anyone.

Villain1 (350x): we don't know anything about him, but his nickname is kind of ReGg1$h

Villain 2 (150x): unknow, but probably a fish, he already limp/called twice

We have 8c 8s, and we open from EP at 100, Villain1 3-bets at 400 from MP, Villain2 calls OTB and we call aswell.

Flop is Kc Jc 8h

and we are first to act.

Questions are:

1) Which is the best line OTF?
2) Are we ever gonna fold here?

Thank you very much!
