Pushing the Marginal (PP vs Overcards)

[Zeldark]

I have seen evidence that the small blind is horrible. Button is also too loose for his own good. Due to a few suckouts on the part of my opponents, I probably seem a little LAGgy.

My main interest is checking behind on the river. Do you fire again?
Of course, general advice on all streets is welcome, as always.
