lol, I'm a mess.

Villain is somewhat of an unknown, although at the time, we had been playing for a bit together on just this table. We've butted heads a few times prior to this, but never have either of us put a signifcant portion of our stacks into the pot against each other. I get the feeling that he's kinda fishy with a clue but luckboxed his way to a big stack. That's just speculation on my part though.

Onto the hand...

Preflop is very sketchy, I know. Obviously I normally fold here but occasionally call with this type of hand particularly in late position. If somebody wants to say 'fold pf', well, I know I have given that advice a lot so I guess I'll just have to take it.

FWIW, I'm guessing that he's opening upwards of 10% of his hands preflop...

Flop and turn seem fairly standard. I'm pretty sure he has a hand like TPTK/TPGK/AA.

River brings 3h and he makes sort of a blocking/value bet. I'm now almost entirely certain that I know what he has (K7 is not even worth a call here against this villain I don't think. He's never put in 3-bets post-flop before.)

As I'm hovering my mouse over the fold button, I tell myself that he can't call a push here. Hence, I push. Bear in mind that I understand how infrequently I have to be good here to make a call correct so please don't point that out. In my eyes it's just risking $476 to win $276 as I'm sure I'm not good.

FWIW I'd be thrilled to do this with a big hand here although since he is not a regular that doesn't really matter.

Hmmm, thoughts?

Pushing is as good as a fold here I think. Chances are he can't call that bet unless he's holding the 2 remaining kings and was trying to induce but I doubt he's that smart given your partial read...he'd probably push here with the nuts. How often do you think he doesn't believe you? Your line looks a lot like a flush draw to me.
