Whiffed Check-raise

Opponent was like 50/6/2. Pretty aggressive. If I whiff on the turn check-raise, how do I maximize value on the river?
Should I just bet turn and keep the initiative?

You played this fine. I c/r these turns very often against aggro players, so NH.

Thanks for the responses guys. I just couldn't believe I didn't make more money on this hand. After the flop call, I was sure he had at least a Q.
