There are no good options here.
Shoving is not great, because this is the bubble, we're one double up away from being in tied first place. If we shove, we ARE likely to get called in two places, we have basically no fold equity preflop.
Check/shoving flops also isn't a great option. Firstly we let multiple opponents see a flop (higher chacne they hit) but also, we may be forced to fold this postflop. It's rare, but lets say we check, and the Small blind decides he likes the flop and bets, we miss and fold right? that's not great, now we have a 2 BB stack. However i really like the thought PO, it's definitely a spot where i'd be looking for extra fold equity!, now if we're in the small blind, we could limp and then we would be first to act and it wouldn't be as bad, but in that situation, we have a BB on a random hand who would likely fold so, again the play isn't quite there.
The only other play is raising smaller. Now, this is where it gets cool. These two players are likely really bad, so they probably don't know stack sizes all that much, i would put in a raise to like 10k here(trying to make it seem as strong as possible, which isn't a stretch, because we are strong here) which leaves us 2k to shove the flop if called. Obviously we're never folding at all postflop, but lets say we raise to 8-10k, the button calls and small blind folds (likely because he folded to a shove right?) we let the 55 villian see a flop, then we shove on him, he might actually fold the best hand there because he's scared of the ace. It's unlikely that this play is going to work, but if theres a chance that these players fold, then in this situation it's worth giving it a go. Basically it's the same as shoving anyways...
The only other thing we can do is try and give a false read to the opponents, but since they are likely really bad, i think this will only make them curious/call more often. You could show a king and tell them you have KK, lol, is that even allowed in casinos?
Anyways, some alternative lines/thinking above. For me, i'd be more than willing to try something, because i'd think that they will both call here really often, and our equity plummets dramatically when multiway. So i like raising to 8k here and shoving any flop if one-both of them call me.
Think about this, if both of them plan on calling you preflop, lets say you make it 8k and then shove flop, even if you get one of them to fold, thats awesome for you!!
