Flop Analysis
Checking back is the preferred play. While we have an underpair and a gutshot, this board hits the SB's calling range quite well, and we benefit from realizing our equity for free.
While our hand has some equity, it lacks the showdown value or blocker profile to profitably bluff the river after the flush completes.

Stabbing small is a high-frequency play here after SB checks twice. We have a gutshot and an underpair that needs protection against random overcards like KQ or J9.
Checking back is the only viable play. The river completes the spade flush and we have zero showdown value, but more importantly, we have terrible blockers to bluff with.
Note: Betting the river is a significant error; 33 has no relevant blockers to the flush or top pair, making it a poor candidate for a bluff.
