Hero ???

I was totally lost, any bet commits me, pushing seems like a huge overbet, and checking will most definitely induce a bluff.

After thinking about this I think I should have bet more on flop, and then raised more, which would have made getting it all in easier on the turn.

As played though, what do I do here?
