We use our range advantage to c-bet the flop and then correctly check-fold the turn once our equity evaporates.
Flop Analysis
Betting small is a strong play here. We hold the nut advantage on this K-high board and use our backdoor heart draw as a high-frequency semi-bluff candidate.
**Ranges:** We have all the sets (KK, JJ, 22) and AK/KQ that BB lacks, allowing us to bet a wide range of air and marginal hands.
**Board:** The two spades and two broadway cards favor our preflop aggression, though we must be mindful that BB will have many Jx and flush draws.
**Sizing:** A 33% pot sizing is ideal; it forces folds from BB's weakest high cards while keeping the pot manageable when we are out of position.

> **Takeaway:** On high-card boards that favor your preflop range, use small c-bets to pressure the bottom of your opponent's range.
Turn Analysis
Checking is the preferred play. After our backdoor heart draw fails to materialize, our hand has effectively zero equity and no longer functions as a productive bluff.
**Ranges:** The 7d is a blank that doesn't change the range dynamic, but our specific combo now loses to all of Villain's continuing range, including their own air.
**Math:** We have only 10% equity against Villain's calling range. Betting 5BB into 10.5BB requires too much fold equity given that Villain's flop-calling range is now quite concentrated.
**Plan:** By checking, we give Villain a chance to check back their marginal hands or define their range with a bet, at which point we can comfortably fold.

> **Takeaway:** When your backdoor equity misses on the turn, stop barreling and look for better spots to bluff.
Note: Betting the turn with zero equity and no draws is over-bluffing; checking is better to preserve our stack when we have no path to the best hand.
