What a crappy spot. Fold to a chop or call to split the drawers money?

Party Poker No-Limit Hold'em, $ BB (6 max, 5 handed) converter

BB ($110)
Hero ($127.95)
MP ($33.45)
Button ($93.25)
SB ($68.60)

Preflop: Hero is UTG with 6[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img]. SB posts a blind of $0.50.
Hero calls $1, MP calls $1, <font color="#666666">1 fold</font>, SB (poster) completes, BB checks.

Flop: ($4) 7[img]/images/graemlins/heart.gif[/img], 4[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, BB checks, Hero checks, <font color="#CC3333">MP bets $1</font>, SB calls $1, BB calls $1, Hero calls $1.

Turn: ($8) 8[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, BB checks, <font color="#CC3333">Hero bets $5</font>, MP folds, <font color="#CC3333">SB raises to $15</font>, BB calls $15, Hero calls $10.


My reads were that SB was most likely chopping with me, and BB is one a flush draw. Call this turn or muck?

I probably shoulda folded or raised preflop also
