LimitO8 tourney hand

[Spellmen]

I guess this is a bubble hand, about 300 entered, 62 left and 40 make the money, blinds are currently 200/400 I have T3500 in chips and am in middle position. The average stack is right around 4700 and the blinds increase in 5 minutes.

Folds around to me and I raise to 800 with A [img]/images/graemlins/spade.gif[/img]10 [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/club.gif[/img].
Folds around to the blinds who both call.
The flop comes 3 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/spade.gif[/img]10 [img]/images/graemlins/club.gif[/img] which looks like the perfect flop for me.
SB checks, BB bets, and I raise, he calls
Turn 3
He bets again and I raise, he reraises which sticks my last couple hundred in. When the turn came, I obviously figured he probably had a 3, but I thought there was a good chance he ONLY had a 3 and hadn't filled up so it looked like I still have a reasonable chance of winning at least one or both ways. Should I have slowed down at all? Possibly fold?
