Flop
3♠ 4♠ T♥

We correctly navigated a 3-bet pot by bluff-catching with second pair and realizing our equity when the action went check-check.

Flop Analysis

Checking is the only play here. We have second pair and a backdoor flush draw, which is too weak to lead into the 3-bettor but too strong to fold.

Flop Analysis

Calling is the correct response to this half-pot continuation bet. We have enough equity with our pair and backdoor draws to continue against a range that includes many overcards.

Turn Analysis

Checking is mandatory. The 8c is a relatively blank card that doesn't change the board texture significantly, and our hand remains a pure bluff-catcher. **Ranges:** BTN's range is polarized between strong overpairs (JJ+) and air/draws (AK, KQ, spade draws). By checking, we allow them to continue bluffing with their air while keeping the pot manageable against their value. **Board:** The board remains Ten-high, meaning our pair of 4s is still second pair. While some straight draws like 65s or 76s picked up equity, we don't need to lead and fold out their bluffs. --- > **Takeaway:** When the board doesn't change the hierarchy of hands, stick to the plan of check-calling with marginal made hands.

River Analysis

Checking is the preferred play, though a small lead is occasionally used. The Qc is a scare card that hits some of BTN's overcard bluffs like AQ or KQ, making our hand even more marginal. **Ranges:** Our range is quite condensed here; we have many hands like Tx, 8x, and small pairs. BTN has many missed spade draws and AK, but the Q also completes J9 for a straight, though that is a rare holding for a 3-bettor. **Math:** We have roughly 54% equity against BTN's range, but much of that comes from beating their missed draws. Checking ensures we don't value-bet ourselves against a Queen while reaching showdown for free. --- > **Takeaway:** On the river, when a scare card hits that improves the opponent's likely bluffs, checking to realize showdown value is the safest path.
