Bet this river.

BB has simply check-called thus far. If he had a king, he would have surely popped the flop or the turn.

If he had the diamond flush draw, he would have surely popped the turn.

Accordingly, you will usually have the best hand here. The only likley holdings that he may have that beat you are pocket pair 77 or bigger (but then again, he prolly would have 3-bet preflop) ... OR .... and King with a weak kicker.


All signs point towards bet.

I do not know where all the assumptions come from as OP did not provide any reads.
I am not sure what is the correct play here but I would check the river.
