1/2 Stud High - Chase this?

I've been thinking about this hand.

In my opinion, the proper call is to Fold on 3rd. If you are interested in tripping up his over-aggressiveness, Raise. But you say you don't know the player. Then let somebody else test him. At $1-$2, his play usually means Qs. This being the case, you are way behind.

Cheers
