We should use our open-ended straight draw to pressure the opponent on the turn, but give up when the river bricks and our equity vanishes.

Flop Analysis

Checking is a sound baseline here. While we have an open-ended straight draw, this board hits the caller's range well, and checking allows us to realize equity without bloating the pot OOP. **Ranges:** The BTN caller has many mid-pairs like 99-JJ and suited broadways that connect with this Q-K-5 texture. Our range has a value advantage with more AA/KK, but BTN is condensed and sticky. **Board:** The two-tone nature and two broadway cards make this very dynamic. Any Ace, Jack, or Ten changes the nuts or our relative strength significantly. --- > **Takeaway:** On high-card heavy boards where the caller is condensed, checking marginal draws helps protect your range and controls pot size.

Turn Analysis

Betting is the preferred play here. The board pairing the King is actually a good card for us to semi-bluff, as it reduces the number of trips in the opponent's range while we maintain significant draw equity. **Sizing:** The 75% pot sizing is effective here to maximize fold equity against BTN's pocket pairs (77-JJ) and weak Queens. A medium sizing forces these hands into a difficult spot. **Blockers:** Holding the Ten is useful as it blocks some of the straight draws Villain might call with, like AT or KT (though KT is now trips). It ensures more of their calling range is made hands we can potentially fold out later. --- > **Takeaway:** When the top card pairs, it often favors the aggressor's range; use your best draws to pressure the opponent's capped holdings.

River Analysis

Checking is the only viable option. The 3c is a total brick, and our J-high has virtually zero equity against a range that called the turn. Turning this into a triple-barrel bluff is low EV. **Ranges:** After calling the turn, BTN is heavily weighted toward pairs (99-JJ, Qx) and now flushes. We lose to everything in their continuing range, and they are unlikely to fold a pair of Queens on this runout. **Math:** We have 1% equity. Bluffs here need to work over 50% of the time to be profitable, but Villain's range is too narrow and value-heavy to fold at that frequency. --- > **Takeaway:** When your draw misses completely on a paired, flush-possible river, don't set fire to more chips—check and give up.
