River theory...an extra BB?

[arx]

After long time lurking, goal in November is to start posting hands frequently, so thanks in advance for any input.

There are situations when a check might earn you an extra bet on the river. Those hands where you are clearly ahead and there is a flush draw that does not get there or an overcard hits the river.

I was trying to find a good example and this is what I came up with. Villain is 40/11/2.21 after 400 hands, but his river agg is 6!!!

Final Pot: 10.70 BB

Ok. So I put him on a busted (?) flush draw or even overcards, so I checked planning on check raising but then...I chickened, because of his river aggr.

Is this a good spot for the theory, ie, a river check to induce a bet and therefore an extra BB?
