2♦ 4♥ 6♠

We correctly realized our equity with a backdoor-heavy high card and bluff-caught effectively once we improved to a pair.

Flop Analysis

Checking is mandatory. We lack range advantage on this low, connected texture and must play our entire range defensively.

Flop Analysis

Calling the small continuation bet is correct to realize our overcard and backdoor flush equity. **Math:** We are getting 6:1 on a call, requiring only ~14% equity. Our hand has roughly 35% equity against a wide button range, making this an easy continue. **Ranges:** Button will bet this texture frequently with air and small pairs. By calling, we keep their range wide and allow ourselves to hit a Queen or a heart draw on the turn. --- > **Takeaway:** When facing a 20% pot bet, you can almost never fold hands with overcards and backdoor potential.

Turn Analysis

We improved to top pair, but checking remains the standard play to protect our range and induce bluffs.

Turn Analysis

Calling is the most profitable line. While the board is getting wetter, our top pair is too strong to fold against a polarized button range. **Ranges:** Button is betting large to polarize. They have straights (35, 58) and sets, but also many semi-bluffs like diamond draws or gutshots (89, 5x) that we beat. **Position:** Being out of position makes raising risky; calling allows us to control the pot size while keeping Villain's bluffs in. --- > **Takeaway:** When you improve to top pair on the turn, don't feel forced to raise; check-calling keeps the pot manageable and keeps bluffs in.

River Analysis

Checking is the only play. Our hand has shifted from top pair to second pair, and we have no value in betting.

River Analysis

This is a pure bluff-catch. The 9c is a relatively clean card, and we must call to prevent Villain from over-bluffing. **Math:** We need to be right about 28% of the time. Given the missed straight draws (5x, 8x) and diamond draws that didn't get there, our pair of 7s is high enough in our range to call. **Blockers:** We don't block the primary missed draws (diamonds or 8x), which is actually good for a call as it leaves those bluffs in Villain's range. --- > **Takeaway:** On boards where many draws miss, second pair often becomes a mandatory bluff-catcher at low SPRs.
