Crazy Pineapple - 2nd Nut Straight Facing 600bb Jam OTF

$1 double-board Crazy Pineapple bomb pot, 6 handed

($.25/.25 NLHE game otherwise)

Relevant Stacks:

SB - $700
BB - $180
MP - $160
Hero (CO) - $350

AFAIK none of these guys have played much Crazy Pineapple outside of bomb pots. SB sat with $100 an hour ago and has been on a massive heater stacking people left and right, often with huge overbet jams and coolering people with a mix of strong hands and total garbage hitting the board. BB is MAWG and a reasonable player, MP is a massive nit. I'm considered tight but have got caught bluffing a few times in medium-sized pots, and got away with a few in larger pots (and showed).

Pot - $6

Board 1 - 7♣T♠8♦
Board 2 - Q♠4♥T♥

SB leads for $20, BB calls, MP thinks for 30 seconds then jams for $160, folds to Hero who peels 3♦6♣9♠ and ???

I look over and SB looks very interested - feel like this isn't a great spot with so little invested facing a bet, call, and 600bb shove, but is this too nitty to fold? Can't imagine if I flat that I fold to a reshove from SB?
