Hey guys!

I ran into this spot yesterday and find myself still unsure if I screwed this up. I open UTG and get flatted by BTN, SB, BB.

BTN is a recreational who flats wide ranges, I have notes on him flatting Q9s in SB vs EP earlier, from SB he regularly flatted JTo, QTo vs random positions. Postflop I don't have strong reads on him.

Seat 1: SB (€76.35 in chips)
Seat 2: BB (€50 in chips)
Seat 3: HERO (€148.71 in chips)
Seat 4: HJ (€56.07 in chips)
Seat 5: CO (€117.67 in chips)
Seat 6: BTN (€50 in chips)

Dealt to HERO [Jc Js]

HJ: folds
CO: folds
BTN: calls €1.25
SB: calls €1
BB: calls €0.75
FLOP [5c 5d 9s]
SB: checks
BB: checks
HERO: bets €1.75
BTN: calls €1.75
SB: calls €1.75
BB: folds
TURN [5c 5d 9s] [4c]
SB: checks
HERO: bets €6.95
BTN: raises €11.55 to €18.50
SB: folds
HERO: raises €127.21 to €145.71 and is all-in
BTN: calls €28.50 and is all-in

Especially with his presumably wide range BTN is certainly able to hold 54s, 65s, A5s here imo. But based on my notes I also have T9s - A9s in his range.

Uncertainty 1: What about the turn double barrel? I figured that if BB was still in the hand I would likely have not doubled here given he has way more combos of 5x but being up against BTN & SB I felt safe betting again.

Uncertainty 2: Facing his turn raise I saw a decent chance that he could still hold some strong 9x like A9s/K9s as well as TT which made me consider and follow through with the shove. I could see him calling off with some of those hands if not always.

But is calling and accepting a check/check vs some of the hands we beat on the river a better line and give him a chance to bluff some of his missed FDs and potentially even fold on a flush completing card?

Vs this examplary range where the combos of J9s, T9s, 87s, 76s are only the cc combos we have 52% equity.

Would strongly appreciate your thoughts on this spot!
