Have you seen him calling preflop raises from big stacks and dump it on the flop? That might give you a clue whether he is set mining or not. I'd probably call the turn and maybe call a reasonable bet on the river, though you'd probably be behind alot. I just can't see dumping KK on this board. Maybe he smooth called AA preflop, but he could just be putting you on overs and betting QQ-TT here. He knows that the 6 did not help you, as you would not raise with a 6 in your hand, so his turn bet in my mind is not as strong as if he bet into a paint card on the turn.
