Set hits ... small stack all in w/ caller...now what

Poker.com $25NL, .10/25 blinds...10 handed

1 limper
EP raises to $1
1 caller
hero calls
small blind calls

Flop: ($3) 9[img]/images/graemlins/club.gif[/img],J[img]/images/graemlins/spade.gif[/img],A[img]/images/graemlins/diamond.gif[/img]
Small blind goes ALL-IN for $3
EP calls $3
Hero ???

Pot is now $9, and hero has $14 left or so.

What should I do here? (see results for my decision)

(a) PUSH.
Why I liked this play: 2 broadways on the board and a big card are always a little dangerous, and there's lots of money in the pot. I can probably isolate w/ the SB.

(b) CALL and try to draw more money out of the villain(EP), who might have called the $3 only because the player was short-stacked and desparate.
What I like about this:
- no flush draws on the board, though the straight draw is somewhat out there
- I might be able to get a few more dollars out of SB

Thoughts?
