When you have the best starting hand on a low board in a 4-bet pot, you are committed to getting the money in.
Flop Analysis
While betting is fine, checking is the preferred strategy to protect our range and induce bluffs on this low, semi-wet texture.
**Ranges:** In a 4-bet pot, our range is extremely narrow (JJ+, AK). By checking, we allow Villain to bluff with hands like AsQs or KxQs that might otherwise fold to a bet.
**Board:** The 7-high texture is relatively safe for our Aces, though it does provide Villain with some flush draw and straight draw opportunities (like 8h7h or 6s5s).
**Sizing:** The 18.6BB bet (roughly 30% pot) is a standard small c-bet sizing for 4-bet pots, designed to keep Villain's range wide while extracting value from JJ-KK.

> **Takeaway:** In 4-bet pots with low SPRs, checking back overpairs can be a powerful way to induce bluffs from an opponent's air.
Flop Analysis
Once Villain check-raises, we are never folding. We have an overpair and the SPR is so low that we are mathematically committed to the pot.
**Math:** We are getting nearly 4:1 on a call, meaning we only need ~20% equity to continue. Our Aces have 77% equity against Villain's range, making this an easy stack-off.
**Ranges:** Villain's check-raise range includes semi-bluffs like KsQs or 8h6h, and value hands we beat like JJ or TT. We only lose to rare sets (77, 55, 22) which are unlikely given the preflop 4-bet action.
**Plan:** By jamming now, we realize our equity immediately and prevent Villain from checking back turns that might complete draws or kill our action.

> **Takeaway:** When the SPR is near 1.0 on the flop in a 4-bet pot, top-tier overpairs are pure stack-off hands.
