fold or call with AK here?

[whiskeytown]

here's the hand - decent read on the other guy - he's fairly solid, but I've seen him commit whole stacks and all in's with 88 - so he's not afraid to gamble with his medium pair.

I raise and get reraised by a limper - at this point I thought I'd just call and see the flop - I had the position, so might as well use it -

we're about 30 players from the bubble in a 10 min round MTT - I can survive with 4 or 5 BB for a bit, so a muck is not entirely out of the question if I truly think I'm beat.

I did the math -

I've got about 2.2K left and I THINK I'm getting almost 5-1 pot odds - (risk 2200 to win 10000) - and a draw to an A or K on the turn or river k comes in about a 3.5 to 1 draw by the river - so I am thinking a call here is good...but I have survived short stacked near the bubble before -

call or muck? - and can anyone give me a good reason for just pushing preflop? - I can't get him out of the hand - I can only see all 5 cards with AK - and that negates any value my position has.
