Checking the river with an overpair protects your range and lets Villain bluff their missed draws, while betting risks getting raised by boats.
While we have an overpair, this low, connected board favors the Button's flatting range. Checking is the preferred strategy to protect our range and realize equity.
Note: C-betting here is slightly too aggressive on a board that favors the caller's range; checking allows us to control the pot and bluff-catch.
The Ten is a relatively safe card. We continue for value, though a smaller sizing is generally preferred to keep Villain's weaker pairs and draws in.
Checking is the correct play. The board pairing the 5 is better for the caller, and our Kings now function best as a high-equity check-call candidate. **Ranges:** Villain has more 5x in their flatting range (like 65s or 54s) than we do as the UTG raiser. By checking, we avoid value-betting into a potential full house or trips while inducing bluffs from missed spade draws. **Board:** The 5c is a significant card; it completes potential full houses for hands like 77 or 44 and makes any 5x trips. It's a 'range-capper' for us, meaning we should lean toward checking our one-pair hands. **Sizing:** If we were to bet, a small 33% pot sizing would be used to thin-value hands like Tx or 88-99, but checking is more robust against a polarized river response. --- > **Takeaway:** On river cards that pair the board and favor the caller, check your overpairs to bluff-catch rather than value-betting into trips.
We must call here. While Villain's overbet is polarizing, our Kings are near the top of our checking range and we only need to be right about 36% of the time. **Math:** We are getting 1.8:1 on a call, requiring 35.7% equity. Given the missed spade draws and straight draws (like 89 or 68), Villain has enough natural bluffs to make this a mandatory continue. **Blockers:** We don't block the spade flush draw, which is excellent—it means Villain is more likely to have those specific missed draws in their betting range. --- > **Takeaway:** When you check the top of your range, you must be prepared to call down on bricks to prevent Villain from over-bluffing.
