Flop
2♠ 6♠ K♥

While our pair of sevens is weak, the BTN's turn check caps their range, making a river fold to a small bet a significant mistake.

Flop Analysis

Checking to the aggressor is the standard play with our entire range on this King-high texture.

Flop Analysis

We should lean toward folding here. While the price is good, our hand is a pure bluff-catcher that blocks very few of BTN's continuing range.

Note: Calling is marginal; solver prefers folding 75% of the time as we lack backdoors and are dominated by BTN's value range.

Turn Analysis

Checking is mandatory. The 9h is a neutral card, and we have no reason to lead into the preflop aggressor after calling the flop.

River Analysis

Checking is correct to let BTN decide their final action. Our hand has some showdown value but cannot bet for value.

River Analysis

Folding here is a mistake. When BTN checks back the turn on a semi-wet board, their range is heavily capped, making our pair a mandatory call against a small sizing. **Ranges:** BTN's turn check-back significantly discounts AA, AK, and sets, as those hands usually barrel for value and protection. This leaves them with many missed spade draws and weak showdown hands that might try to steal the pot on the river. **Math:** We are getting 3.8:1 on a call, meaning we only need to be right ~21% of the time. Given BTN's capped range and the small bet size, our pair of sevens is well above the required equity threshold. **Plan:** By calling here, we protect our checking range and prevent opponents from profitably bluffing whenever the turn goes check-check. --- > **Takeaway:** When the aggressor checks back a dynamic turn, their range is capped; you must be willing to bluff-catch wide against small river bets.

Note: Folding to a 35% pot bet after the turn went check-check is too tight; our hand beats all missed draws and BTN is capped.
