Played on Partypoker, so no handhistory.
Tournament was a 109$-Sat. 5 Players remain only first gets ticket. I'm 4. in chips.

UTG (HJ), Stack 28BB
CO Stack 26 BB
BU (Hero) 24BB
SB, 18,5 BB
BB, 36 BB

UTG opens for 2,2BB, CO calls 2,2 BB. I have 88 and I jam.
My thougt prozess:

UTG is a pretty loose player, he has to fold a lot.
CO just calls, so he can trap with AA, KK but obviosly very unlikely. He has probably not a premium holding.
I can call here but will have to fold on most flops so not really a good idea. Also BB is a good aggressive player. With his big stack he has a fantastic squeeze spot.
Also I can fold but this seems too tight. I don't think that ICM is a big concern here because we are not really near the money. But I have to admit I'm not an ICM expert.

I still think my play is best, but I'm interested in your opinions. How would you approach the hand? What would be your thought process?

Also is there anybody who have solved or can solve this spot? I have some experience with solvers and GTO but not multiway.

I would play this spot in the same way. I think you have a lot of fold equity here and will pick up the dead money frequently. Even if you get called 88 has decent equity.

There is no ICM in winner take all spots. Just play to maximize chip ev. If anything, there is a tad bit of reverse ICM, since coming in 2d is the worst spot.
