Isolation play or throw away?

Party 30+3 3-table, 2 tables left around 14 players, 5 pay. SB used his entire time bank to call. BB has folded for an orbit and SB has played alot of hands but only shown down good ones. SB has alot of chips so if I do an isolation play I probably dont want him to call. Whats my play?

I'm not throwing this away. If SB didn't reraise I don't think he has a hand strong enough to call a push. I'd push it in and get heads with the BB.
