($11) 5's in BB nearing bubble

Please critique my thinking:

No particular reads, the whole table seemed solid, maybe a little on the conservative side. I’ve been showing only good cards recently (in the last orbit I had twice re-raised all-in in response to short stack all-ins and won both, showing pocket 9’s and AKs).

Party Poker No-Limit Hold'em Tourney, Big Blind is t150 (5 handed) converter

Hero (BB) (t2365)
UTG (t1030)
MP1 (t1150)
MP2 (t967)
Button (t2488)

Preflop: No SB. Hero is BB with 5[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/heart.gif[/img]. Hero posts a blind of t150.
UTG calls t150, <font color="#666666">3 folds</font>, <font color="#CC3333">Hero raises to t600</font>, UTG calls t450.

Flop: (t1200) 9[img]/images/graemlins/diamond.gif[/img], 3[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>

I had been hoping villain would fold to my raise – since he only called UTG, I put him on two broadway cards or A-small – but I had him covered and I was prepared to call if he went all in, figuring I would likely be in a coin-flip. I didn’t know what to think when he only called (for half his stack) instead of pushing, and decided I would put him all in on any ragged flop.

Should I have just pushed preflop?

Any comments will be appreciated.

edit - sorry about the messed up action, the converter didn't like having no SB (last hand's BB busted out), I think I've fixed it all of it now.

FYP.

If you're going to raise, you should (almost) always push when you have less than 10 BB OR when your only opponent has less than 10 BB.

Just check preflop. Your action is all skewed as well, you have you as BB raising, then BB calling, when I imagine you to mean UTG called. I don't like your line here unless UTG is a right donktastic muppet.

I posted but misread the stack sizes.

I would just check and take it from there. There is no need to blow off half of your stack if he has a real hand.

Thanks for the comments.

I've only been playing SNG's for about a month, and feel that I've been weak-tight near/on the bubble. But I can see that a small PP might not be the best time to try to be aggressive when UTG's call means he probably has a hand.
