When the flop checks through, use small turn stabs with weak made hands to protect your equity against overcards.
Flop Analysis
Checking back is the most robust play here. Our marginal pair has decent showdown value but is too vulnerable to bet for value or turn into a bluff.
**Ranges:** While we have a slight range advantage as the preflop raiser, the SB's calling range is dense with Jx and 8x. Checking back allows us to realize our equity without facing a check-raise that would force us to fold.
**Board:** The texture is semi-wet with a flush draw present. By checking, we keep the pot small and avoid over-investing on a board where we are frequently behind the SB's top and middle pairs.

> **Takeaway:** On J-high boards, check back marginal pocket pairs to realize equity and avoid bloating the pot against stronger condensed ranges.
Turn Analysis
After the SB checks a second time on a brick turn, their range is significantly capped. A small bet here functions as a 'protection' bet to deny equity to overcards.
**Sizing:** The small sizing is effective because it targets the SB's high-card hands (like KQ or AT) and weak draws. It forces them to either fold their 6-out overcards or pay to see a river with a range that is mostly losing to our pair.
**Ranges:** Since the SB didn't lead the turn or c-bet the flop, they rarely hold a Jack or a set. Our marginal pair is currently ahead of their 'air' and high-card hands, making this a high-frequency stab in theory.
