chip leader in a $55 Party rebuy, confusing top pair hand

[bruce]

I bet the turn and if he c/r's I fold. I then check the river.
I don't see how the second Queen helped him. By checking the turn you really have no idea where you stand on the river. He
can fire with anything from a made hand to a stone cold bluff. Because you checked the turn you are left guessing. Just because there's no draw on the flop doesn't mean we can
assume our opponent flopped a set or has a bigger King. He may have called with middle pair, an over pair, or wheel draw and he's taking a card off and watching to see if you
will fire a second barrel. I think you played the hand way
too tight, barring any specific reads, which you don't have.
