Depends on how deep you are. 44 BB isn't deep enough to pass on Aces. Depending on the tournament structure, 44 BB is 10 BBs in an hour of play (if it's a faster format, the value of a single hand significantly go up). Depending on the structure the payjumps are really flat, others are very top heavy (on top heavy MTTs you should play more to win and make FTs than to cash). 44 BB is possibly a call even with JJ or TT depending on how the tourney is made. Though I might find some folds in a 150+ BB effective stacks shove, but not in the regular ATC shove, though. KK is hard but I fold. QQ fold for 150 BB without thinking twice. Trash like K2 gives you a sweat.
OTOH:
UTG shoves for 15 BB
UTG+1 re-shoves for 25 BB
MP2 re-shoves for 40 BB
CO calls for 17 BB.
Hero is BB with 22 BB and looks down Aces.
Slow MTT format, flat prizepool, bubble of the Final Table?
I think it's pretty clearly a fold here. Unless you're all about them braceletzzzzzzz like a Negreanu.
