Villain complete unknown.
OTF: It's a spot we can both have nuts but I have more T9 than he does cause T9o being the bottom of my pre defend range I chose to bluff.
I think hearts I can have here is KhJh KhTh Th9h(nut) Ah2-Jh 7h6h 6h5h.
And prob flat KhJh AhJh.

OTT: I cannot have AK but I do not see him having AK either. I'm blocking Ah and only possible AK he can have is AdKd (1 combo).

OTR: Here, I don't think villain has a 9 almost not anytime. I think 9 would made raise OTT unless its sth like Th9h (I'm blocking all Ah9h ish combos). <- Do they not?... Do people flat 9 OTT a lot?
even if the villain flatted flop w/ AdKd, I do not it X/C twice on this board and its only 1 combo.
I think the villain's range mainly consists of two pairs and sets and maybe some KhXh-pair type hand.
I'm afraid that my jam would exactly like what i have; broken nfd but I see myself having bunch of T9o combos here so I chose to jam.

Am I overbluffing in this spot? Do I get heroed a lot or do they have more 9 or AK combo than I think? D:
