Help with effective stacks

[ChipSpeak]

I posted this hand a while back, but Gobbo's answering everything.. I'd appreciate an experienced point of view on this one..

Read here, MP2 is a maniac. Button is a thinking TAG 21/11 ~75 hands.


PokerStars No-Limit Hold'em Tourney, Big Blind is t50 (9 handed) internettexasholdem.com

BB (t4025)
Hero (t4270)
UTG+1 (t1765)
MP1 (t1908)
MP2 (t780)
MP3 (t2780)
CO (t1253)
Button (t1438)
SB (t3306)

Preflop: Hero is UTG with A[img]/images/graemlins/heart.gif[/img] K[img]/images/graemlins/club.gif[/img] .
Hero raises to t150, UTG+1 calls t150, 1 fold, MP2 raises to t780, 2 folds, Button raises to t1438, 2 folds, Hero ??

I ran it through the stove, I am 35% in main pot, 51% in side with button on a reasonable 99+ AJs+ for button and random for maniac.

I received a couple of replies saying easy call.
Considering
* lost chips are more valuable than gained
* I am very deep early
* The stack to my immediate right can double me
* the hand is at near dead even pot odds.

Should I be looking for better spots this deep?

If you're not folding now, at what effective stack is this a fold?

Ok, but at what MP2 stack size do you fold?
