Stealing and getting caught...

These are the sort I never know how to play - when you start stealing, and then catch something. Should I just give this up on fourth?

I don't really know what's happening - I can't think of a hand that has a call on fifth, and then can't bet sixth. If he does bet sixth, is this just a check/fold?

The river has to be a call getting 5:1 with no bet on sixth, surely.
