[50NL] 99...BB vs SB. Interesting river spot

Villain is 33/24 over 885 hands. ATS from SB 45%, 71% CB.

Had been a lot of blind vs blind 3betting/4betting, same w/ BU vs blinds w/ me and villain. Villain is capable of double barreling w/ air blind vs blind

Thoughts? One of only two rivers I'm calling as original plan was to call 2 streets only, then I hit my set and he bombs...

fold turn, fold river as played

Definitely calling turn on double flush draw multi-gutter board. I would fold the river because it makes no sense for him to overbet anything but a value hand here. You'll have a flush like 15-20% of the time so it doesn't make sense to overbet value with worse than a flush and I don't think you'll see a bluff here often enough. Basically, IMO you'll have enough flush and flush blocking hands to make the calldown here without being very exploitable, and I don't think he's out to exploit you that much anyway with his idiotic line.

I think that you have to go fold. However, there is a big possibility to villain have straight or flush. I know that three nines is hard to throw away, but I think that going fold here is the right move.

I'd 3bet pre against this guy at least. Def call turn. I'd often raise even, but only if there's a dynamic that I feel I can read well.
