AK in level 1 with 2 raises before me

[Dave613]

Hi all,
this was a frustrating loss at a 20+2. I was assuming that my reraise was large enough for 1 of them to fold, but I was apprehensive about pushing because MP2 was so shortstacked (willing to go allin). I realize that this is abit contradictory and I now think I should have just pushed (but I also now know that MP3 had KQ and probably would have folded if I pushed...though he SHOULD have folded with my 200 raise anyway right?). How would you have played this differently?
