Well no, because he might have any two overcards, in which case I don't want to let him check behind something like Kx on the river, and he may fold a hand sometimes that has 6 outs vs me. It just so happened that he had a good overpair here, but if you aren't checkraising the turn after checkraising the flop at least some small percentage of the time with less than top pair, I think you are giving up something.

Also, I'm confident in my read that he wouldn't 3bet here when I'm ahead, so I lose a fraction of a bet when I'm behind.
