Villain checks, Hero.....?

bets 7 and hopes for a crying call from KK?

Check behind on river and make a note.

Did he also have AK? I often find when a villain really baffles me, he's got my hand.

I think betting out on the river is just a little too thin. I say check behind and river an A on 6th street.

Are you joking, Wike or are you really checking the river? Why?

RESULTS:
After his river check, I KNOW he has a margianal hand and fakebluff/overbet $15 expecting a fold, or a call from TT, 99, 88, KK, JQ maybe, in that order. I was horrified to see.... KcTh. Hunh. Really?

the utg minraise is the sign of the donkey imo... i try to get it in pre...

I would have checked the turn like you did, bet $8 on the river, and lost to the straight.

A note about this hand, the turn did not improve your hand all that much even though it looks like it did. The only hand that you pulled ahead off was queen-jack (which I think you realized when you checked). The problem with this hand is after the four-bet preflop, this is a very bad flop. The only decent hands that you can beat now is ace-ten which usually doesn't get four-bet preflop (it turns out the villain had king-ten so that is an interesting play) or king-king which is going to see the ace on the board and come to a screeching halt (which is why I like the feeler bet on the flop, the perfect size too). So AK is a split, KK you can beat, and everything else you are behind.
