Eff Stacks £500

Preflop (£4): Hero is CO with 8♣7♣
UTG limps, HJ makes it £15, Hero calls, SB calls
UTG is a old guy loose/passive that can get crazy sometimes bluffing, sawing him try bluffs twice. HJ is a loose/passive old guy calling station-overplaying hands. SB is a aggressive player who likes to get it in a lot.

Flop (£60): Q♣3♣T♣
Checks to me. Hero bets £40, SB calls, UTG makes it £125, Hero tank calls, SB shoves £300, UTG tank shoves £480.
At this point I was sure SB had the A♣, and I wasn’t sure what UTG could have. I think he definatly has QQ, 33, TT, QT in his range and only flushes I beat are 5♣6♣ and 5♣4♣. With SB in the hand I think we have to call. Also, once we call the £125 bet we have to call £345 to with £1315, effectively 4:1. If some make arguments to fold then the fold must be to the £125?

Thoughts?

It's probably a very hard fold. I think we're dead. We're not committed.

UTG's range is probably not going to have QQ and TT in it. Also, a live loose passive old guy is probably flatting here than c/3betting QQ, TT, QT, 33. When passive players generally become very aggressive, it's generally a red flag. And given this definitely does not look like a bluff spot, I think we're dead to UTG a good chunk of the time.

Not too scared of SB's range. Ace of clubs certainly in his range.

UTG definately flopped a flush and is not bluffing, and it is not the nut flush, so you already could be behind, or you could be crushing him. and don't just limit his range to connected suitors. Just because those are the flush draw hands that you would play, passive gambly types of players have K6 in their range pre.

who knows what SB has, but for the price that you are getting, and as you describe both V's, I am never folding here.
