We correctly c-bet for protection and value, then bluff-caught a check-raise before pot-controlling on a dangerous straight-completing turn.
Flop Analysis
A small c-bet is preferred here to deny equity to Villain's overcards and extract value from middle pocket pairs like 88-TT.
**Ranges:** We have a significant range advantage on King-high boards as the 3-bettor, holding all the AA, KK, and AK combos that UTG often just calls preflop. Villain's range is condensed to hands like middle pairs (JcJd) and suited broadways.
**Sizing:** The 33% pot sizing (5.4BB) is ideal on this texture; it forces Villain to continue with a wide range of marginal hands while keeping the pot manageable if they show aggression.
---
> **Takeaway:** On K-high boards as the 3-bettor, use small sizing to pressure the condensed range of the caller.
Flop Analysis
Facing a check-raise, our Jacks become a pure bluff-catcher, but we have enough equity and a backdoor flush draw to continue IP.
**Math:** We are getting 2.1:1 on a call, requiring roughly 32% equity. With our middle pair and J-high backdoor spade draw, we have about 45% equity against a range that includes AsQs and 6s5s.
**Ranges:** Villain's raise is polarized between sets (33, 44) and semi-bluffs like nut flush draws (AsJs). Folding here would be a massive over-fold, especially since we block some of their value and unblock their spade bluffs.
---
> **Takeaway:** Don't fold strong pocket pairs to a single raise on wet boards when you have the necessary pot odds and backdoor equity.
Turn Analysis
Checking back is the only play here as the board becomes highly connected, bringing several straights into play.
**Board:** The 5d is a terrible card for us, completing straights for A2s, 67s, and 26s. It shifts the nut advantage toward Villain's check-calling range from the flop.
**Plan:** By checking, we realize our equity and keep the pot small. Our hand is no longer for value, and betting would only isolate us against hands that have us crushed, like 5s4s or sets.
---
> **Takeaway:** When the board texture becomes highly connected and favors the defender's range, prioritize pot control with one-pair hands.
River Analysis
Checking back the river is standard; we have decent showdown value but cannot expect to be called by worse if we bet.
**Ranges:** Villain's range is capped after checking the turn and river, likely consisting of missed draws or middle pairs like 99. However, our Jacks are at the top of our checking range and function perfectly as a showdown winner.
**Math:** The SPR is low (1.25), but there is no incentive to jam. We lose to all Kx and straights, and we don't expect 99 or 6c5c to call a shove.
---
> **Takeaway:** On the river, if you can't identify enough worse hands that will call a bet, take your free showdown.
