After SB checks again, we continue to check back. Our hand has showdown value against their missed draws and small pocket pairs.
Folding here is a slight mistake; we should call the majority of the time because we don't block the primary bluffs SB would hold.
Note: Folding 77 here over-folds against a range that contains many missed spade draws and low-frequency air bluffs.
