can definitely see an argument for checking, I think CB of 1/2 is still the right play. it's not always about the hand your in, but sets up for future hands as well that you actually hit. Say you lay this one down to a reraise or the others even fold. Next time on a made hand other players see 1/2 pot sized bet and think you are CBing again and you now have established a trap type play. It is not always ONLY about the current hand you are in.

As i said, i can still see an argument for checking. So much of these cases are read dependent and texture of the flop dependent.
