darbday;293014 wrotebet the turn so worse hands will call and have to pay a price. its makes the river easier too. now that you checked the turn you kinda should call the river because you gave him a chance to bluff.
maybe look at it this way;
you raised pre-flop and bet flop, then checked turn. How many guys raise then c-bet when they miss, then don't fire again? It justifies his bet by both replies above.
As for OP, you might be able to answer yourself by asking; Why did you check turn?
His bet size I like and maybe a bit small, but it reeks of value bet, either to sell the bluff or because he did hit king and knows your spooked by turn and river...he may even get you to fold a small king here.
