£20 rebuy tourney

[three1ne]

82 started. £20 rebuy and top up after an hour.

15 left, 9 paid. Blinds 500/1000.

I have 2.4k left with 77. I am third to act and am prepared to go all in. First to act raises to 2k. 2nd to act reraises to 6k.

I fold.

Should I have called all in here and hoped for the best? Not really interested in making anything but the final 5 which doesnt have a great chance of happening
