If you think he will exactly check worse hands on the turn and bet better hands, than your choice is easy check-fold turn. If it goes check-check, only bet the river if you think he will call with worse hands.

If you think he will bet worse hands, but not call with them, than check-call turn.

If you think he will bet neither worse nor better hands, but will call with worse hands, than bet all in turn.

If you think he will bet worse hands and call with them on the turn, than bet all in.
