river decision with four to a straight on board

[waffle]

BB is a TAG. I've only observed solid play from him.
MP is loose passive.

What should I do as first to act? Check/call 1 bet? Bet/fold?

I would bet/call only hands you're worried about are like 89 or 78. He could have easiliy had a flush draw, two pair, or top pair. I see him having more hands that will call a bet than will bet if you check, that you can beat.
