We must never fold the nut flush draw when getting excellent pot odds, especially when our overcards provide additional equity.
While calling is acceptable, shoving is the preferred line at this low SPR. We have massive equity with the nut backdoor flush draw and two overcards.
Note: Shoving is superior to calling here; it maximizes fold equity against Villain's non-spade overcards and protects our 54% equity.
Folding here is a significant error. We have picked up the nut flush draw and are getting a price that requires very little equity to continue profitably. **Math:** We need 32.4% equity to call, but we actually have over 53% against the SB's range. Even if we only count our 9 flush outs, we have roughly 20% equity, and our Ace/Queen overcards often remain live against Villain's bluffs. **Ranges:** Villain's range is polarized between strong made hands and semi-bluffs. Since we hold the As, we never run into a better flush, making our draw extremely clean and our equity realization high. --- > **Takeaway:** Never fold the nut flush draw when the pot odds are favorable and your draw is "clean."
Note: Folding the nut flush draw when getting 2:1 odds is a massive blunder; we have the required equity to call against almost any range.
