So I didn't really like any of my option in this hand. Villain was ~54/22.7 and fold to 3-bet of 0 over a few hands. The SB was a reg that was active in 3-betting so I really didn't want to build a flatting range here. I felt that the 4x was a bit more indicative of a stronger hand from a fish, given his PFR was only 22 anyway so it was a somewhat condensed range for a fish. I really just wanted to ISO, hence the small sizing, but was a bit unsure of if it was +EV against his continuing range, and really didn't wanna get 4 bet which is exactly what happened. On the other hand I don't want to be straight up folding T9s here. Any thoughts would be appreciated.
