Confused in short handed game!

[1wizard1]

Hand in a short handed case game last night:

4 players, 25p/50p

I'm on the button

MP folds
Button raise to £3
SB fold
BB Raise to £12

I have JJ.

Player is solid but does like to bluff, i have a fairly tight image.

What do i do here? Call fold if i dont hit my set?

If i hit it i push,

Or do i just fold PF

I actually folded and BB did not show.

Similar hand happende later in the night with 88 althou that time i was up against a much tighter player.

Any Advice?
