pot odds or tourney standing??

[DarrenX]

2405 in chips, table leader, 7 left. 75/150 blinds, I open in mp to 400 w/T [img]/images/graemlins/diamond.gif[/img] T [img]/images/graemlins/club.gif[/img]. Solid player with 1150 thinks a bit and goes all in. Complete idiot, who earlier called 2 large stack all ins w/Q9o thinks and goes all in for 1225- it's back to me. Pot is a PHAT 2775 and it's 825 to call. does 3.4-1 make it a must call, or fold to save a healthy stack?

(converter didn't work, so here's the rough HH if interested):
