Shoving has to be +EV given the amount in the pot even though you'll never fold out both, you'll certainly fold out one unless they are fully loaded. An SnG could be good too. I think you need to give us a better read on SB. I'd assume he's CC-ing speculative hands and monsters but reraising AJ/AQ type stuff. Obviously, going for an SnG is a disaster if he ever leads the flop.

Edit: and some indication of how tight the table is and how big stacks in front are seeing as when you fold here you have no resteal FE and are looking at push-folding from now on.
