OK to check/call this river?

[Durs522]

I have no solid reads on either player in this hand. It is my first hand at the table. I watched MP play over cards and he was very passive with them. Check calling an AJ down the whole way. I felt he would play an AQ the same way in this spot.

On the flop and turn I'm not trying to do anything fancy here. I feel the best line is to just bet out since we're most likely ahead. None of my opponents has shown any aggression so I think our hand is good, howeve they could be on a draw with a KQ or Q9.
