i'd bet flop b/c i expect villain(s) bluffing fqcys to be suboptimal in a 3way pot. Also 2-tone incentivizes the bet a little more.

I'd fold river but i think it's still tough b/c he could easily have QQ and maybe some fraction of other dominated sets which gives you a lot of equity. it's bad that you don't have the Ac, and bad that he probably checks most of his FD otf in this 3way formation. i think i would read it as him using a PSB b/c he thinks he looks super disguised w/ a flush and just wants to maximize with a nutted hand. wouldnt be surprised if QQ uses a smaller sizing on avg. lastly tournament factors would have me folding away some chip EV here anyway.

Bet bet bet. This deep their preflop flatting range will have tons of gutshots and flush draws and your hand can face heat. UTG being an unknown incentivizes me to call on this field in which 4k worth a lot on early stages.

Absolutely need to bet this flop. I'd personally be betting 1200-1350, and I wouldn't argue vs betting more. There are a lot of not good turn cards for us, and with top set we are not going to get away from this hand easily.

As played, I'm folding river. He just shows up with the flush way too often here, and we are still super deep, so if he's bluffing us then fine. Let him bluff us. While I agree he can show up with QQ here, I don't think he does that often enough for us to be +EV to a PSB here. I'd likely call 2k, which is probably worse because it's so much more value sized for him.

Thanks for tone of good advice it seems clear, that beting flop is beter. With ace of clubs do u prefer checking or useing mixed starategy here? With stacks, that we can get all chips in on 2 streets do you start checking?

Thanks for detailed response. Got to work on my deepstak/postflop game.
