[pheasant tail (no 18)]

Wouldn't SB 3-bet you PF w/ an over pair or fold all mid one gappers?

You've been known to raise a bit light w/ draws in position at cardroom in question. SB might play it that way w/ A7s, 98.

UTG is predictable so it seems like you can find out for sure on turn if you are beat by her. Few people can go for an overcall w/ a set on 4th st.

You're closing the action. I think a peeel is in order. The pot does have 7 BBs.

BTW, you play your position well so a call will make the SB just as nervous as a cap. You might feel more sure after you see his (and UTG's) reaction to the turn card.
