I would think most of the time you are against A /images/graemlins/diamond.gifQ or some other hand that is scared of the flush. Maybe even a set of 3's or 5's. Actually it's the SB in an unraised pot, so he could have Q5 or Q3 as well.

Anyway, this is an autocall for me, even on Stars. If it's flush over flush then so be it.

You can't fold this.
