Villain is a fairly new 28/20 reg-appearing player. SB steal 67% over 240 hands.

On one hand he's not repping much of anything and should never have nutted hands like T9 where I can. On the other hand, well, he's not repping anything and should know it so I'm not sure how often the player pool is bluffing like this. I also have a ton of better hands in my range to call the river with so does that make this an easy fold?
