Don't fold Ace-high when you still hold the range advantage; continue with your best high cards to prevent being exploited.
Flop Analysis
Small c-betting is the preferred strategy on this paired texture where we hold a significant range advantage.
**Ranges:** We have the nut advantage with all the AK, KQ, and AA-JJ combos that the Button lacks after just flatting preflop.
**Board:** Paired boards are relatively static; the Button either has a King or they are forced to fold a large portion of their air and weak pocket pairs to any aggression.
**Sizing:** A 1/3 pot bet (2.1BB) is efficient here, putting the Button's wide floating range in a difficult spot without risking too much with our own air.
---
> **Takeaway:** On paired King-high boards, use small sizing to leverage your range advantage and deny equity to the opponent's overcards.
Turn Analysis
Folding here is a significant mistake as we are over-folding a hand that actually maintains an equity lead over the Button's betting range.
**Math:** We are getting 3:1 on a call, requiring only 25% equity to continue. With ~29% equity and the Ace of diamonds, we have enough to continue, especially since we can win at showdown if it checks through the river.
**Ranges:** Despite the flush completing, we still hold the range advantage (53.5% equity). Because our range is so strong with Kx and flushes that checked, we must defend our best Ace-high hands to prevent the Button from bluffing profitably with any two cards.
**Plan:** The solver actually prefers a large raise (53% frequency) as a bluff. By raising, we capitalize on our range advantage and force the Button to fold their own bluffs and marginal one-pair hands.
---
> **Takeaway:** When you maintain a range advantage on a draw-completing turn, don't let a single bet push you off your best high-card hands.
Note: Folding Ace-high here is too tight; we have the equity to call and the range advantage to support an aggressive raise.
