We flopped a monster and used a deceptive check-call line to induce a river raise-bluff from our opponent.

Flop Analysis

Flopping the second nut flush is a dream scenario. Checking is the standard play to protect our range and allow HJ to continue with their high-frequency c-betting strategy.

Flop Analysis

Calling is the most effective way to keep HJ's bluffs and marginal made hands (like AsX) in the pot. Raising here would fold out everything we beat except the nut flush.

Turn Analysis

Checking again is correct. We want to give HJ another opportunity to barrel with their air or thin value hands like AQ or AA with a spade.

River Analysis

After HJ checks back the turn, they are often capped at one-pair hands or missed draws. Leading for a pot-sized bet targets their Qx and Tx holdings that might check back again. **Ranges:** HJ's turn check-back significantly discounts the nut flush (AsXs), as that hand would typically continue for value. Our lead looks like a polarized attempt to steal the pot, which can induce 'hero calls' or bluffs. **Sizing:** The pot-sized lead is effective here. It maximizes value from Qx while setting up a perfect SPR for a potential raise-shove if HJ decides to get creative. --- > **Takeaway:** When the preflop aggressor checks back a wet turn, don't be afraid to lead the river for a large sizing to extract value from their capped range.

River Analysis

HJ's raise is a massive gift. Since we hold the second nuts and HJ's line (check-back turn) makes the nut flush extremely unlikely, we must jam for maximum value. **Blockers:** Holding the Ks is critical. It blocks the second nut flush, meaning if HJ has a flush, it's almost certainly lower than ours (like Js9s or lower). More importantly, it unblocks the As, which HJ would use to bluff-raise this river. **Ranges:** HJ's raise is highly polarized between rare slow-played monsters and total air (like AsX). By jamming, we target the top of their 'bluff' range that might feel priced in to call, or simply realize our 92% equity against their raising range. --- > **Takeaway:** When you have a near-nut hand and an opponent raises a capped line, the only response is to shove and maximize the value of their mistake.
