88 in SB, limped around preflop.

9 man $6.50 SNG, all 9 still remain with blinds at 25/50
My stack was about 1100 at the time. I had no good reads and everyone in the pot had me covered (or just about).

4 of the 7 to act in front of me had already limped in and I had 88 in the SB.

My 2 thoughts were either limp behind for set value, or push all-in to try and grab the 275 in the middle after everyone had shown a good amount of weakness by limping. The factor that made me decide to push all-in was the thought that the BB might see 5 limps as passive and try the big all-in steal himself.

What's the best play to make here? Set value limp, all-in steal, or a smaller raise?
