Flop Analysis
Checking back is the most robust play here. While we have the range advantage as the preflop raiser, J-high has almost no equity and doesn't benefit much from protection.
While we improved to second pair on the river, we must fold to the lead as we block the missed straight draws Villain would need to be bluffing.

Checking back again is mandatory. The board has become significantly more dangerous with the flush completing and the straight draw (3x) getting there.
Folding is the correct play despite improving to second pair. When the SB checks twice and then leads into the aggressor on this runout, their range is heavily weighted toward value.
Note: Calling here is a losing play; our hand is a poor bluff-catcher because we block the primary missed draws (J9, QJ) that Villain would use as bluffs.
