Folding bottom pair with the nut backdoor flush draw is too tight against a single continuation bet, even when facing a large sizing.

Flop Analysis

We must call here. While CO's 129% pot overbet is polarizing, our hand is too strong to fold immediately; we have bottom pair, the nut backdoor flush draw, and an overcard kicker. **Ranges:** CO's overbet range is polarized between strong value like sets (44, 55) or overpairs (KK, AA) and bluffs like King-high (K9s, K8s). By holding the Ah, we block some of their strongest Ax bluffs while retaining enough equity to continue. **Math:** We need roughly 36% equity to call. With 55% equity against CO's betting range, we are well above the threshold, even accounting for the difficulty of realizing equity out of position. **Plan:** We are looking for an Ace, a Four, or a Heart on the turn. On brick turns, we can evaluate based on CO's sizing, but folding the flop allows Villain to over-bluff us with impunity. --- > **Takeaway:** Don't over-fold pairs with backdoor draws to large bets; these hands are the backbone of a resilient defending range.

Note: Folding bottom pair with an Ace kicker and nut backdoor potential is a significant mistake; this hand has more than enough equity to continue against a polarized overbet.
