Small stack, small blind, modest holding

[AhabCaptain]

$10 MTT, 576 entrants, 120 left. Blinds at 150/300. Have been struggling with bad cards but managed to stay alive so far. UTG and dealer seem solid, BB loose and lucky. At 10 player table: UTG calls, 6 fold, dealer calls, I pick up AcJs in SB. The stacks of the two players that already called and of the BB are all around 7000, mine is a modest 1780. Fold, call or push?
