3♥ T♠ K♠

We correctly defended our top pair, but the Ace turn and spade river made our hand a pure bluff-catcher against a polarized range.

Flop Analysis

Auto-played to reach this drill spot — you didn't act here, so it isn't scored.

Turn Analysis

Checking is mandatory. The Ace is a significant range-advantage card for the Button, and our top pair has now been demoted to second pair.

Turn Analysis

Calling is the only option here. We have enough equity against the Button's semi-bluffs and we cannot fold a hand this strong to a single turn bet. **Ranges:** The Button's range is wide, containing many gutshots like QJ or spades draws that will bet for protection or as a semi-bluff. Our pair of Kings sits comfortably in the middle of our defending range. **Math:** We are getting 2.2:1 on a call, requiring roughly 31% equity. With nearly 47% equity against their betting range, folding would be a massive mistake. --- > **Takeaway:** Don't over-fold second pair on the turn when the price is fair and the opponent has plenty of natural semi-bluffs.

River Analysis

Checking is pure. The 4s completes the flush and the wheel straight (25), making our hand extremely vulnerable to the Button's polarized betting range.

River Analysis

Folding is a disciplined and correct decision. While we are at the top of our folding range, the Button's pot-sized bet represents a very polarized range that crushes our one-pair holding. **Board:** The river is quite bad for us; it completes the spade flush and the wheel straight. Our 5s is a poor blocker here as it actually blocks some of the missed straight draws the Button might have bluffed with. **Ranges:** The Button has a significant nut advantage with all the flushes (Qs8s, Qs5s) and straights (QJ). By betting full pot, they are forcing us to have a very strong hand to continue, and a weak King simply doesn't qualify. --- > **Takeaway:** When the board gets highly connected and the opponent uses large sizing, be prepared to let go of marginal one-pair hands.
