late stage hand

[NYplayer]

this is from a live tourny. i have 9K left after posting the 600 sb. blinds
are 600/1200 with 100 ante. averge stack is around 16K. 9 players at table. folded to CO who raise
to 4400, he has about 30K. pot is 7100. I have Ad9d. I went all in. maybe i should fold.
maybe i should call and bet any flop? he had JJ and won. it's 2700 in
each pot and i have 9K left so my M is just a little over 3. is this
the time to make my move or shoudl i fold?
