UTG open is a TAG playing 13/9 with 15 R1 on about 200 hands.
BB with a small sample was a 23/5.
I was playing 10/8 with a 17 R1.

PF, being the UTG open a TAG a prefer flatting.
As played, on Flop what would you do?
The donk Shove normally has some T (JT+) or Flush draw and only a few times a randow 6. Against this range we are +70% favourite on flopzilla.

The UTG Flat worried me, but which hands he would isolate him? JJ+. Does he call the BB shove with QhJh+, AhJh+, AT and fold to a squeeze from me? The only flats that reaally worried me were 66 or TT. 88 and 99 i think he just fold because i still have to decide. Saying this we are near 65% favourite on flopzilla.

What is your opinion?
Best regards

i dont like flat calling here. It puts you in a world of pain when you get flops like this. As played after the call from utg2 i think its a angry fold. One of them is proabably drawing for a flush and the other likely has an overpair/boat

Fold as fast as u can. This is QQ+ or boat almost always.

definitely folding now.

No 3b preflop? In a spot like this I raise PF everytime.

As played, you may be ahead on flop, but not so often that you can be sure a call is correct.
