Check back weak pairs on the turn for pot control, and never call check-raises with underpairs that cannot realize equity.

Turn Analysis

Checking back is mandatory here. Fives have decent showdown value against air, but firing a second barrel accomplishes neither value nor meaningful fold equity. **Ranges:** The Small Blind's flop-calling range is condensed around hands like second pairs (Q9s), top pairs (KJ, QJ), and middle pocket pairs (88). A turn stab folds out missed high cards that we currently beat and isolates us against hands that crush us. **Plan:** Checking in position allows us to control the pot size and cleanly take our showdown on non-threatening rivers without putting more chips at risk. --- > **Takeaway:** When holding a marginal underpair with no redraws, check back to control the pot rather than turning showdown value into a useless bet.

Note: Barreling the turn with an underpair accomplishes neither value nor fold equity; checking back for pot control is the pure play.

Turn Analysis

We must fold facing the check-raise. While the price to see a river is cheap on paper, calling with an underpair that lacks redraws bleeds chips against future pressure. **Ranges:** The check-raise represents extreme strength, featuring sets like 99 and 22, strong top pairs, and semi-bluffs with gutshots or open-ended straight draws like KQ and QTs. We beat none of the value and hold poor equity against the bluffs. **Math:** Getting 4.4:1 requires 18.6% equity, but raw pot odds are deceptive when our equity realization is terrible and almost any river puts us in a guessing game. --- > **Takeaway:** Do not let favorable pot odds tempt you into calling check-raises with underpairs that cannot comfortably realize equity.

Note: Calling a check-raise with an underpair and zero redraws is heavily -EV despite the tempting pot odds.

River Analysis

Checking behind is the only sensible play. With straights and flushes now completing on the board, we simply take our showdown without committing further chips.
