He c/c Q87 two flush board, and never bet again. I checked it down w/ AT and rivered a ten. He plays ok from my estimation despite that I hate the way he played 66 there.</font>

He did instacheck the turn fwiw and I do realize my river bet is awfully thin, but we do know villain is calling my cbet super light.

either 77 or hes bluffing a smaller pp

i like think river bets but this is too thin i think.

i would check/fold river. he called your raise preflop and thus, he has to have some hand. he then called your cbet, even though he may lightly call it he called it with a KK6 board with a flush draw. So, he's either on a draw and or he's shown that he doesn't think you have K. His range, given what you have said, is quite wide...i doubt he's playing anything less than a pair...i'm thinking anywhere from AK to small pair.

As played, I fold to the river raise. I would go for a c/c on the river I think.
