I think this is pretty awesome.
I think calling the 3-bet pre-flop is close. We're calling off 11% of effective stacks here, which is a lot, but we are 3-way, and these guys are representing super strong ranges (UTG open and a 3-bet at a relatively early blind level and no antes), so I expect to get paid off a lot when we hit.
I think your bluff is awesome because there really aren't many J's or T's in these guys' ranges, unless they have lolquads. I don't know if you have any reads on these guys, but I really don't expect UTG to raise/call pre with AT or AJ. I also think hands like KJ, KT or worse are rarely in his UTG range (readless).
MP2's 3-bet range at this level is generally super strong. His bet sizing over an UTG open and a call also screams strength. QQ+, AK sounds about right.
I feel like MP2's flop check says his range is pretty polarized between the slow-played stone cold nuts (like TT and JJ, which I didn't put in his range above but are possible though super unlikely), air hands like AK that don't want to c-bet 3-way, or a draw like KQ, which I doubt he has. I don't think MP2 checks the flop with QQ+ as the board is pretty connected, and he can get value from a J.
On the turn, UTG's check indicates weakness. MP2's bet looks weak and is easily trying to steal the pot after 2 opponents check, both indicating weakness. UTG may be check/calling with a draw like KQ, A
x
, or even a naked A thinking it's good a lot here.
And while I doubt they have many T's in their range, and Zeebo tells us they almost certainly won't fold a T, anyway, it's not impossible that you bluff someone off the second-nut full house here. I'm sure you're not relying on that because it will almost never work, but it's a small consideration.
So I really like this. I'm pretty sure I would have instantly folded the turn, but thinking about, I think it looks pretty good, and I think you get them off overpairs (and obviously overcards) a lot. If someone snaps with quads, it's unlucky imo.
