We correctly called the flop with our backdoor equity but made the right discipline fold when Villain polarized their range on a blank turn.
Flop Analysis
Calling is the only play here. We have the nut backdoor flush draw and an overcard, which provides enough equity to continue against a small 1/3 pot continuation bet.
**Ranges:** SB will c-bet this paired board frequently with their entire range, including air like Q9s or JTs. Our hand functions as a high-quality bluff-catcher that can improve on many turns.
**Math:** We are getting over 4:1 on a call, requiring only 19% equity. With our overcard and backdoor spades, we comfortably exceed this threshold against SB's polarized range.
---
> **Takeaway:** Don't fold Ace-high with backdoor draws to small c-bets on paired boards; you have too much equity to give up.
Turn Analysis
Folding is correct. Once SB follows up with a massive overbet on a total brick, our Ace-high loses its value as a bluff-catcher and we no longer have the odds to chase.
**Sizing:** The 1.2x pot overbet is highly polarized, usually representing trips (Q7s, 76s) or strong overpairs (TT-AA). By using this size, SB is trying to maximize value and force folds from our marginal hands.
**Ranges:** While SB has bluffs like Jd9d or Th9d, we don't block any of their value and we lose to their entire 'thin value' range like 8x. Without a direct draw, we cannot justify calling such a large bet.

> **Takeaway:** When the board bricks and Villain overbets, let go of your marginal high-card hands that lack direct draw equity.
