You need to raise on either te flop or turn. You have top pair decent kicker, short-handed. You probably have a good deal of hands which the button will raise with beaten. Against an unknown who appears, I would likelly, check-call then check raise. The other acceptable line is check-raise flop and then bet the turn.

As for the river, you have to check call since you have no info on where you are int he hand and he will likely bet a much widen range of hands than he calls with here.
