10/20 Commerce Aces

La-I typically bet this flop but had a feeling he hit his set of K's. Without knowing villian, I put him on queens or kings possibly jacks preflop.

I guess my line of thinking was I am either crushed or way ahead and I don't want to lose my stack in this situation and can call down not to concerned with free cards

After checking the flop, I initially felt the turn K was a decent card until he checked behind.

Looking for a better line overall

thanks
