OK.
So the payout is 31.94, 23.24, 17.47, 12.14, 9.14, 6.07.
7,000/14,000/1,750 ante
UTG: 152,111
MP: 59,089
CO: 276,939
BTN: 465,814
SB: 115,715
Hero (BB): 433,332
BTN raises to 28,000, Hero raises to 84,000, BTN raises to 464,064 and is all-in
The pot is 28,000 + 84,000 + 1,750*6 + 7,000 = 129,500
If you fold:
UTG: 152,111 - 1,750 = 150,361
MP: 59,089 - 1,750 = 57,339
CO: 276,939 - 1,750 = 275,189
BTN: 465,814 - 1,750 + 129,500 = 593,564
SB: 115,715 - 1,750 - 7,000 = 106,965
Hero (BB): 433,332 - 1,750 - 84,000 = 347,582
If you call and lose :
Hero: 0
Therefore $EV = 6.07, you win $99.
If you call and win :
BTN: 30,732
Hero (BB): 880,664 ♠_biggrin:
Now we can calculate everything we need with an ICM calculator.
$EV Folds: 20.117
$EV Call & Lose : 6.07
$EV Call & Win : 27.370
What equity do we need for a +$EV call?
[EV$(fold)-EV$(lose)]/[EV$(win)-EV$(lose)] * 100
((20.117-6.07) / (27.370-6.07)) * 100 = 65,94%
MP2 65.73% 65.33% 0.41% { TT }
MP3 34.27% 33.86% 0.41% { 22+, A2s+, K6s+, Q9s+, J9s+, T8s+, 98s, 87s, 76s, A2o+, K8o+, Q9o+, J9o+, T9o }
If he 4-bet at least 35%, you can call here 
This is why I would not 3-bet here. Villain can easily 4-bet anything and we can't really call without a read. I don't like this 3-bet/fold (it's basically a bluff) when the hand is good enough for a flat.
Flat > 3-bet/fold > fold >>>>>>>>>>>>>>>>>>>>>>> 3-bet/broke
