Yet another biggest POT EVER!!!

This one will probably be the biggest for AWHILE!!! I've been fortunate in getting a lot of these lately... This hand is not only the biggest $$$ pot, but the biggest BB pot ever for me, though. I have a feeling that this will stand for awhile (hopefully not :-) ).

This is just a WOW hand... Wow...

We're so deep-stacked, I debated 3betting. However, I did not want to find myself in a spot where I'm out of position facing a 4bet. Therefore, I take a flop.

Flop: ($10.00) 7s Qs 3s (3 players)
Hero bets $10, UTG+2 calls $10, BTN raises to $20, Hero calls $10, UTG+2 calls $10
Wow. BTN's min raise is very scary. I'm most afraid of a set of Queens, but I'm also afraid of flopped flushses. UTG+2's twice flat is even scarier. I'm pretty sure he's on AsKx.

Turn: ($70.00) 3d (3 players)
Hero bets $15, UTG+2 calls $15, BTN raises to $29.60 all in, Hero calls $14.60, UTG+2 calls $14.60
Loving life, and I'm almost certain BTN has a set of Queens, if not trip 3's. I'm praying for another spade.

River: ($158.80) 4c (3 players - 1 is all in)
Hero bets $70, UTG+2 raises to $193.45 all in, Hero calls $123.45
Club sucks! I thought it would be the end of action with UTG+2. However, he surprises me with a HUGE all in shove of 194BBs. Now, I'm very very very concerned that UTG+2 has quads or a set of Queens, and perhaps the BTN had the flush, but I have SO MUCH vested here, that I'm not laying down my middle 7's full. Remember that the UTG+2 is a 14/7 which is plausible to be raising QQ here, so I'm generally discounting the quads. The other hands that make sense for a 14/7 are AKs, and very very very unlikely 44 (I would think he would have folded long ago).

Final Pot: $545.70
UTG+2 shows 8s 6s (a flush, Queen high) - From a 14/7? I'm not getting this line at all.

Essentially, on the river, UTG+2 turns his hand into a bluff. I'm pretty sure of what he put me on, but it's doesn't make sense: His all in raise says Queens full or 3's full. He has to put me on a suicide bluff or a turned boat, given the way the hand played out. Moreover, he has to expect, given the action, that there is likely a higher flush than his. As a corollary, I have to think that even an A high flush may be folding out here on the paired board. His shove represents the VERY top of the range.
BTN mucks Ts Js - Even BTN had a better flush!
