How do we know SB will bet again if a flush card hits? He does have 3 opponents. On top of that, we have 9-15 outs, or somewhere between 36-60% equity in this 4-handed pot. SB is not guaranteed to 3-bet, and even if he does, we still may get another caller (and even then we can cap for value/free card).
