** Not much to go on here due to sample size but previous play tells me UTG does not raise outside of the top 5% of hands (99+ , AJs+, KQs, AKo)

Pre Flop: (pot: 1.5 BB) Hero has Ks Qc
UTG raises to 2.5 BB, fold, fold, fold, BTN calls 2.5 BB, fold, Hero calls 1.5 BB

Flop : (8 BB, 3 players) 8h 7c Td
Hero checks, UTG bets 6 BB, fold, Hero calls 6 BB

Turn : (20 BB, 2 players) Jd
Hero bets 9.55 BB, UTG calls 9.55 BB

River : (39.1 BB, 2 players) Js
Hero bets 20 BB, UTG raises to 50 BB, fold

UTG wins 76.3 BB

My thoughts:

Preflop: my hand is crushed by UTGs range so I am definately not interested in a raise. A call is priced in by the BB and an additional caller offers me good pot odds to see a flop so I would lean towards a call. If you argue for a fold here I'll really like to hear the argument.

Flop: Flop helped my range a lot more than the UTG raisers and I'm intersted what you think of a donk bet here. I didn't donk bet here as I worried about multiple opponents picking up enough equity to call.

Turn: Picked up some equity.

As for how much equity i figured i had 8 clean outs to win and 6 dirty outs to get to showdown. So approximately 11 outs if you discount dirty outs at 50% (I dont think this is what good players do ) to get about 19% equity (The actual equity against his the range i posted above according to PT4 is around 20%)

so i bet for additional fold equity trying to continue what I was hoping would look like a failed check-raise attempt on the flop and get UTG to fold and take down the pot.

River: Barreled again and lost

I think i played this hand badly but i'm not really sure exactly where . I also feel like I would really benefit from some (long or short) feedback so let me have it!

fold flop, Imo super optimistic float
turn fine, river also

only thing that I like in this hand is preflop call. Flop is clear fold, the fact that this board doesn't hit UTG and it's MW and he still cbets makes his cbet range stronger IMO.
BY leading turn and betting river you cap your range to Q9 at best and any good player will know that and can raise you quiet library.

He knows that he has ever possible FH in his range so he can start turning hands into a bluff if he is good.

I don't know how you can rep a failed c/r when the action went perfectly for you to c/r.

Assuming villain isn't blindly cbetting boards (and even if he is if he only opens top 5% here as you suggest) then just fold the flop. Even the bottom of his range on that board has you crushed.

you're right. That comment made 0 sense hahaha . Appreciate your advice on the rest.

You rep exactly 4 combos of Q9, that's it, worst river to continue your bluff on as you haven't got any boats in your range. He can raise with any boat with impunity and also bluff you a decent percentage of the time as a result.
