To my eye this is a clear bet turn and call down scenario. I think many of our holdings can now check for a free card. Hands like AQ, AJ or some lower pairs like 77 can all check here. QQ is too high up in our range to be checking and we need to charge hands like AQ, AJ, 77, A9c, etc. on the turn.
Our opponent did not check raise the flop, making K's less likely. A Ten would be a logical holding for him but that is now less likely that there are two on board.
If you bet and he raises just call down, especially if he's loose and aggressive. You may induce a bluff raise from some draws here. Don't be afraid, they are only plastic chips
