77, smallish stack, but strength shown by 2 others

[AZnuts]

Live NL tourney, $60, 100 entrants, about 45 left, starting stacks of T2000.

BB300, going to BB400 real soon, Hero is in the BB now, 8 handed table.

UTG+1 (T2500), raises to T1000
MP+3 (T3500), raises to T2000
Hero is BB,(T1800 incl blind) 7[img]/images/graemlins/diamond.gif[/img]7[img]/images/graemlins/heart.gif[/img] ??

I'd push this hand first in, and probably against the lone open-raiser, but 2 opponents? A fold will leave me with T1350 after my SB, w BB400 coming. Take the shot to triple up here, or concede and hope for a decent shot the next orbit?
