my only reasoning for a fold would be that i was so very short stacked that i probably only stood a chance at 3rd. 4th place sucks.
Being short is a reason to call, not to fold. We call tight in a SNG because, as long as we have a good position in the tournament to defend, doubling up isn't anywhere near as good as going out is bad. But the worse your position gets, the less you have to defend.
Here your position in the tournament is very bad and if you fold then, unless CO is only limping monsters, BTN will take the pot, you'll have 3BB, no fold equity and probably hands that are worse than AK, btn will play carefully against the big stacks because he wants to wait for you to bust and take third, which is what will usually happen. So folding wont gain you a lot of 3rd places, just 4ths, calling will give you 3rds.
If big stack was pushing, you had a stack that was a bit more decent and there would be a real shorty around, then you would have something to defend and might get to fold because of ICM.
