No stats or reads on villain, but just like 2 or 3 hands earlier (the last time villain opened) I 3bet him IP, he flatted OOP, then he folded to my c-bet on a Kxx flop. I decided I'd abuse him again until he shows signs of fighting back. So I flop gold, and he donks. I read this to be a bluff most likely, so I flat. The turn is shit though cause if he has TT+ I'm now beat. Granted, I thought his donking range is monstly bluffs, but it's possible that he's got a better 2 pair now. Still, in hindsight I wish I would have bet turn because he most likely barrels his TT+ hands, plus he's obv probably 4betting TT+ cause he thinks I'm FOS now. So I stupidly check back, and the river is pretty bad, and villain shoves. This would normally be a horrible spot if I didn't have a strong suspicion that villain is fed up with me abusing him. Call or fold?
