We correctly navigated a low-board texture by checking back our marginal pair and calling a tiny river probe.

Flop Analysis

Auto-played to reach this drill spot — you didn't act here, so it isn't scored.

Turn Analysis

Checking is a solid mixed strategy. While we picked up an open-ended straight draw, our hand still functions well as a check-back to realize our equity for free.

River Analysis

Calling is the correct play against this tiny 25% pot sizing. Our 55 has turned into a pure bluff-catcher, but the price is too good to fold given the missed straight draws in the BB's range. **Ranges:** BB's range is air-heavy after checking twice, containing many missed overcards like QJ or JT. However, the 25% sizing can be polarized, and we lose to any 6x, 7x, 8x, or the straights (45, 59, 9T). **Math:** We are getting 4:1 on a call, meaning we only need to be right 20% of the time. Given the BB's wide range and the small bet, our pair of 5s has more than enough equity to continue. **Blockers:** Our 5s are actually somewhat 'bad' blockers here because they block some of the straight draws we want Villain to be bluffing with (like 45 or 59), but the pot odds override this concern. --- > **Takeaway:** When facing a tiny river probe after the action goes check-check, you must call with your best bluff-catchers to avoid being exploited by wide stabs.
