Flop Analysis
A small c-bet is effective here. We have a range advantage on this Ten-high texture and our specific hand has a diamond backdoor and two overcards to the middle of the board.
We correctly identified a spot to bluff the river when checked to twice, but must fold when the opponent shows unexpected strength.

Checking back is the most prudent play once the board pairs. The 5s is a better card for the Big Blind's range, which contains more 5x suited connectors than ours.
When the BB checks a second time on a blank river, their range looks extremely capped. Using our King-high as a bluff is a high-frequency play to fold out their weak pairs and high-card hands. **Ranges:** BB's range is mostly composed of missed straight draws (67s, 78s) and weak 4x or small pocket pairs that checked twice. By betting, we put maximum pressure on these marginal bluff-catchers. **Blockers:** Our Kd is a useful blocker as it reduces the combinations of K-high hands the BB might try to hero call with, though its primary value is simply that we cannot win at showdown. **Sizing:** The 75% pot sizing is designed to look polarized. We are representing a Ten, a slow-played 5, or a total air-ball; this sizing forces BB to fold everything but their absolute best bluff-catchers. --- > **Takeaway:** When an opponent checks twice on a static board, their range is often capped, making it an ideal time to turn your no-equity hands into bluffs.
The fold is mandatory. The check-raise from the BB is a massive outlier given the previous action, usually representing a slow-played 5x or a rivered set/two-pair that we cannot beat. **Math:** We need roughly 37% equity to call. Against a check-raise on this board, King-high has 0% equity as we lose to every single value hand and even the BB's rare bluffs. **Ranges:** While we expected BB to be capped, the raise uncaps them. They likely have 5x, 99, or TT. Since there are no missed flushes or straights to bluff with, this is almost always value. --- > **Takeaway:** Don't fall in love with your bluffs; when a capped range suddenly shows extreme aggression, respect the strength and fold.
