Almost everything puzzles me about this hand

[stlip]

As a longtime limit player I'm struggling to adapt to NL.


Party 10+1 SNG
Level:3 Blinds(25/50)

6 handed

UTG ( t2747 )
MP ( t898 )
Button( t990 )
SB ( t505 )
<font color="blue">HERO </font> ( t1355 )
BB ( t1505 )

UTG <font color="red">raises </font> [150] MP folds HERO (CO) calls, Button folds, SB <font color="red">goes all-in </font> [455], BB folds, UTG calls [355], HERO folds.

Both players turn over AQo.

I didn't raise when I entered the pot because I thought there was no reason to provoke a duel with the big stack. But the hand seemed too good to lay down, as well. When the SB went all in I was disappointed that I didn't get to be the one to call and see if my PP could hold up for a nice pot with no additional risk for me. But maybe that would have been the wrong play anyway.

Was the SB nuts to push and the chip leader a little nuts to call and I did the safe and sensible thing? (No way I should have called, too, right?) Should I have put in an additional raise when I entered the pot precisely to discourage anyone from doing anything crazy because I wanted to see this flop.

Appreciate any insights into what my line should have been and what my two opponents might or might not have done better.
