Checking down second pair in position at shallow SPR maximizes equity realization against missed broadways.
Flop Analysis
Checking back top pair is standard here to control the pot on a coordinated board.
**Ranges:** SB's 3-betting range features numerous high-equity overcards like KdQd alongside strong overpairs like AhAs. Checking back denies them an easy check-raise and keeps their broadway air in the hand.
**Math:** With an SPR of just 0.71, betting marginal top pair commits too much of our remaining stack against hands that have us crushed or possess huge draw equity.
---
> **Takeaway:** At shallow SPRs, check back medium-strength top pairs on wet boards to realize showdown value cleanly.
River Analysis
Checking back to take showdown is the only play with second pair.
**Ranges:** SB's range after three checks is overwhelming air, packed with missed broadways like KhQh and KsQs that we beat. Betting accomplishes nothing because worse hands fold instantly while overpairs like AhAs call or shove.
**Plan:** Take the free showdown and collect the pot against their heavy missed overcard frequency.
---
> **Takeaway:** Never bet a marginal showdown hand when only better calls and worse folds.
