I'm BB on an active table. My table rep is probably tight

This is the action and cards as I'm remember it, in essence it's correct, it may not be exactly correct.

UTG+2 (loose'ish but not crazy) raises to 6, guy next to him who plays nearly all hands calls, buttons (tight) calls and I look down at pocket fives and call.

Flop comes down J J 5. I check to raise but it checks all the way round. Turn is 9, I bet out 14. call, fold and call. River 3, 3 cards to a flush. I bet 35 on the river, UTG+2 immediately raises all in, button tanks a short while and calls. I have £120 behind, both players cover me.

How did I play it up to the end and what to do then?

What are the other players' stack sizes? I know they have your 120 covered, but it still makes a difference how much they actually had. I'd be a lot more worried if the BTN called off 250 than if he had like 145.

I'm probably just calling this off for 60bb, was there a flush draw OTF? Seems to me that slowplaying trips on that board is possible, add flushes into the mix and we have to call IMO.

It looks like JJ(1 combo) and 99(2 combos) beat us, so 3 hands beat us there are a ton of hands that could be doing this that we beat, so for 60bb definitely a call and hate life if he has one of the three hands that has us beat.

To me it looks like UTG+2 was slowplaying Jx and button hit some sort of backdoor flush.

We also lose to J9...

Why is this a puke spot? There are 10 combos of reasonable hands you lose to and a ton of stuff you can beat. Folding would be a massive mistake.

Yeah, I'm dumb...

snap call

Really interesting and this is why I post on 2+2!!!! I thought it was a hard fold but not that hard with an all in and a call but the consensus here is that it's an easy call. I winged and moaned for a little while and eventually folded. UTG+2 showed J 9, BB showed J K off.

If it was just UTG+2 that was all in, I would have called but I actually thought the BB's call, who was a pretty nitty player (clearly my read was wrong and nitty was actually just bad!!) meant I was most likely losing to him and maybe UTG+2.
