The ace turned all those busted ace-highs into top pair, so the card that was a blank for you is a gift for the button. Their river range is now value-heavy and your king is only second pair — calling pays off a range you no longer beat.

K9s on K♠ 8♥ 3♣ 2♦ A♥ facing a bet — call or fold?

Q: K9s on K♠ 8♥ 3♣ 2♦ A♥ facing a bet — call or fold?

Fold. The river ace changes everything. All those busted ace-highs the button barreled — AQ, AJ, AT — just paired the top card, so the card that was a blank for you is a gift for them. Their river betting range is now loaded with value, and your king is only second pair. The bluffs that would have paid you off didn't get there; the ones that did beat you. A bluff-catcher works when you beat the bluffs, and on an ace river you no longer do. Fold and save the $30. The solver folds about 90% of the time.

The answer

Fold

the ace kills it

The math: The ace is the worst card for you: it smashes the button's range (every A-x just made top pair) while your king drops to second pair. Their bets are now far more value than bluff. Fold.

The idea behind it

Before you bluff-catch, read the river card against villain's range. A card that completes or improves their bluffs — like an ace when they've barreled a lot of ace-high — shifts their betting range toward value, and your bluff-catcher becomes a fold.
