Flop Analysis
Facing a small c-bet on a paired board, JJ is a mandatory continue. We are ahead of all their air and draws, only losing to Qx and the few overpairs they hold.
We use our overpair as a bluff-catcher, relying on the Jack of spades to block the nut flush on a dynamic river.

The turn is a complete brick. BB continues their aggression, but our hand strength remains unchanged relative to their range. We must continue to realize our equity.
The river is the most difficult decision of the hand. The 8s completes the flush, and BB shoves for full pot. While our hand is just a bluff-catcher, the specific suits we hold dictate the play. **Blockers:** Holding the J♠ is the primary reason this call works. It blocks the nut flush (A♠J♠) and other spade-heavy value hands like K♠J♠, significantly increasing the likelihood that Villain is polarized toward missed broadway bluffs. **Ranges:** Villain's range is heavily polarized between Qx/Flushes and total air (AK, AJ, AT with no spades). Since we block a portion of the value range, we must call at a high frequency to prevent Villain from over-bluffing. **Math:** We are getting 3.1:1 on a call, requiring roughly 24% equity. Given the number of missed straight draws and non-spade broadways in a standard BB 3-bet range, JJ finds enough winning scenarios to make this profitable. --- > **Takeaway:** On flush-completing rivers, use your specific blockers to choose which bluff-catchers to call with; blocking the nut flush makes a marginal hand a winning call.
