Both players are very loose passive, BB in particular. UTG is not fancy enough to just call this turn with a 9, so I'm pretty confident I'm ahead of him. BB likes to donk bet when the traditional person would c/r. He's done this with two pair hands, turned flushes, and also a rivered top pair in a heads up battle.

A rivered 9 will give me a guaranteed extra 2BB since they will both call on the chop. Getting 6.7:1 on the turn, plus the chance my hand could still be good, what's my line?
