(Live 3/6) -- AA in the SB

(Live 3/6) -- Gerneral table makeup is very loose passive, I have a pretty TAG table image. BB is a middle aged gentleman typical calling station. Villain in this hand is a decent player (compared to rest of table), but he seems to overplay many hands, his range of hands include TT-AA, AQ, AK, KQs.

Im concerned with my play on all streets...

I think my flop play is standard and correct, and on the turn when the diamond hits, I think my bet and call is correct. The river, I am a little unsure on though, can I check fold this hand here?
