I think check-raise turn is far better than check-call turn.

Look at it this way, if he's on one pair or a draw I think a check-raise is far superior. The advantage to check-calling I see is catching a river bluff, and I don't think people are going to bluff you much after you called the turn OOP, that shows some strength.

Suppose you check turn, he bets, and you know he's got AT. What would you do?
