vs unk
I decided to cb F because this board dont hit him often
I bet T because A is quite scarry for his 8x, 7x, pp.
Im not sure about R - he shouldnt have much Ax. I can have lots of them.
He dont have FD to often also.

I think that bigest problem is his stack size = so hi is much toward fish. I shouldnt try to bluff fishes...ehh

I'd probably go for a delayed cbet on this board... it hits BB's calling range much better than your UTG open range.

What is his cc range vs UTG open?

He has a ton of pairs & pair+draws on this board... He'll be calling pre with lots of suited connectors and suited one-gappers that get a piece of this board

You have only a few suited connectors that hit this board. Most of your range is two high cards and suited aces

Disagree. This flop is almost a stereotypical "good for the BB's range" kind of flop. He's unlikely to have an overall equity advantage, as you have more overpairs, but his continuance range is pretty damn strong. (Once he's folded his Broadways, he's left with all the sets, two pairs and pair plus draws. He can also have flopped the nuts with 65s.)

I would check the flop, it completely missed our range and hand. Bluff only some BDFD.
As played rather give up river. If you wont to bluff river do it with a diamond blocker. You cannot have many bluffs with a rather narrow value range.

x flop
ap I think 75%-pot river is profitable as bb doesn't have enough Ax or flushes and some straights/sets/2p x/r flop or turn. I would overbluff this river

cbetting flop isnt as bad as it looks. His range is likely too wide and wont xr enough

Before I noticed its prob. fish I put him on pp, all suited broadways, AJ-AQo, T9s, 98s.
I didnt gave him hands like 65s. Im not sure its ok to call it on BB vs UTG OR.

I bet R and he call with 73s - so my pre assumtions is **** :]

exactly, especially against a 2.2x open

x flop.

is he a fish if he calls with 65s on the BB vs utg open?

note his stack

65s standard call bb vs any position

Could you tell me what is your def. range vs UTG or in vacum?
I have something like this:
https://gyazo.com/64ddbc02b1297d05c909b1d2cfe8924d

depends on how nitty utg is and open size
vs unknown 2.5x open you can defend ATo, KQo (KJo/QJo too but meh), all AXs, all pairs, 54s+, all suited 2gappers (but I fold the lowest ones), Q9s,K9s, theoretically some more KXs

delayed cbet spot at these stakes if ever saw one. If checked to twice you will take the pot down with a 75% sized turn bet almost every time on this turn card

I drop the Q9s and add 76s, 65s and 54s. I usually call AJo and sometimes ATo as well. It depends who opened. I go a bit wider if the raise is only 2.5x, and a lot wider vs a minraise.

The small suited connectors should do pretty well vs UTG, since they aren't dominated much, so usually have "2 live cards". That's not the case with Q9s. Villain has no worse queens in his range, and often no worse 9s either.
The smaller cards also give you board coverage blah blah blah. i.e. If you want to rep something strong on the low flops that UTG usually misses, you need to have those hands in your range.

Stab smaller, 1/3. Delayed cbet is also fine, for the most part you don't want to bet with naked non A hi card equity on semi connected boards. UTG vs bb is different because of range advantage so you can get away with stabbing more and barrelling more on turned or rivered broadways
