$120+10 deep $20k gtd

I recognize villian's name but no reads or notes. Did I play this way too passive or is it ok OOP? I was planning to c/c turn and then as played c/c river fwiw. If you bet anywhere I didn't, what's your sizing? Thanks a lot.

b/f?

Bet turn. Only hand that turn helped is J,10. Also, many overpairs are still in villain's range that you need to get value from. Also, must price out flush draw. imo
