NL100 value bet river?

[veryblind]

NL100 live. Effective stacks between villain and I are $300 (he has me covered).

Villain (MP2) is a LAG who has been getting really lucky after just sitting down for 30 min.
I have a TAG image. I'm dealt K [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/club.gif[/img]

Preflop: MP1 limps, MP2(villain) limps, I limp in CO, SB completes, BB checks
Flop ($10): K [img]/images/graemlins/diamond.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/club.gif[/img]
checks to me, I bet $10, BB calls, MP2 c/r to $20, I call, BB calls

(I didn't know what this min-c/r meant actually. I was hoping to evaluate again on the turn. And if he did have 2 pairs, i figure a diamond would slow him down... .although a 3rd diamond probably makes BB the best hand here.)

Turn ($70): 6 [img]/images/graemlins/spade.gif[/img]
checks to me, I bet $35, BB folds, MP2 reluctantly calls

(MP2's check surprised me. I thought I may have had the best hand and decided to bet to see where I was. Also, I wanted to bet so no one throws in a much larger river bet. I expectied to be checked to on river for showdown value)

River ($140): 8 [img]/images/graemlins/diamond.gif[/img]
checks to me

Should I value-bet this (maybe $50)? What hands would you put villain on?

villians line makes no sense at all so we have no idea where he is at and this board got ugly and i think that you should be happy to show this hand down, b/c u will be pissed once he c/rAI

What worse hand will call a value bet here? There arent any (unless villain is an extreme donk)so just check it down.

[Fiasco]

1) raise preflop
2) bet more on the turn, the c/r c/r line is pretty unlikely
3) I say check behind on the river. I think that a flush draw is the hand most likely to min craise the flop, and I dont know where we are in the hand. I think you should be happy to show this down.
