Meh, this is a FML spot where you hate life and all options suck. On balance after thinking about this spot for a bit I think I fold, at the table with less time to think I'm sure in this spot i'd be jamming sometimes, but i think in a vacum i think a fold is best.
With the stacks being pretty even no one, except perhaps the biggest stack, is in fold to advance mode
Getting your chips in first right now is huge I think position/picking the stacks that you shove on outweighs your actual cards. I'd be looking around for someone who I thought was good and would play 'correctly' and be jamming on her.
Even if the blinds pass through you, then youll still have a stack which can decimate everyone except perhaps the top two stacks and really the stacks in 3rd to 5th and 7th-8th shouldn't be calling you with anything but premiums. In an everyone plays optimal world you should have a few orbits of midstacks jamming into other midstacks, the shorties jamming into the midstacks and the biggest stack doing fuck all and just wait for a couple of people to get coolered.
It really was a FML spot. You see the AK and life is all good, you're ready to shove and pick up the 10k in the middle. Then someone shoves and you just sink.
I still don't know what the correct play is. Really bad spot. I'm just glad it was only for a £336 seat and not something bigger.
