Thanks for Not Stacking Me, Bro! (Part 11)

Today I managed to take down a 90-man donk-n-go. But I wouldn't have gotten there if I hadn't survived this hand early on:

Seat 1: bruechips (BB) (3,915)
Seat 3: UTG+1 (2,745)
Seat 9: SB (5,880)

*** HOLE CARDS ***
Dealt to bruechips [8d 4d]
UTG+1 calls 60
Button calls 60
SB calls 30
bruechips checks (Happy to see a free frop)

*** FLOP *** [Qd Ad 3d]
SB bets 60
bruechips calls 60 (I frop an 8-high frush. Many a time I would raise here. I decided to just call b/c the sb's small donk bet usually indicates a weak 1-pairish hand. I don't think he has a big-diamond kind of hand, which I think he'd either check/raise, check/call, or lead bigger. He might still call a raise and maybe a bet on a blank turn with his weak one pair though, which is why I'd often raise. But I also thought the limpers behind me would likely raise with their big-diamond hands, as well as sometimes complete air, which would squeeze the SB and allow me to get more value. Finally, I'm calling here a lot with a QsTd or A9o kind of hand, so I want to mix in calling with some flushes and sets, so that I'm not too vulnerable to raises from limpers or 3 big barrels from the SB.)
UTG+1 calls 60 (This is interesting and somewhat worrisome.)

*** TURN *** [Qd Ad 3d] [As]
SB bets 60
bruechips raises to 390 (The SB min donks again and I raise, hoping to get value out of his ace, and protect my hand somewhat against the board pairing again or another ace coming.)
UTG+1 raises to 960 (Ridiculously strong raise here from this guy. I have a hard time even putting him on AK or AJ. He has to realize that I could easily have those hands beat and not want to bloat the pot too much. There are plenty of boats he could have, such as 33, QQ, AQ, or A3s. He could even have AA. Add in KJ/KT/JT of diamonds, and that's 18 hands I'm drawing stone cold dead against. Even adding in AK and AJ, 16 hands that have 10 outs to fill up or better on the river. So I'm well behind his range, assuming this is never a total bluff, which I think is absolutely accurate.)

UTG+1 shows [Kd 9d] a flush, Ace high (A flush I didn't expect him to have with his early position limp, but I was indeed drawing dead. And in case you're wondering, shoving as a bluff has approximately a -58% chance of being successful. Tourney donks aren't going to give you credit for a full house and fold a fropped frush 45 bbs deep.)
