3♠ 6♥ 6♠

We correctly checked down a vulnerable two pair on a four-flush river where our hand had shifted from value to a bluff-catcher.

Flop Analysis

Checking is the preferred play here. While we have the range advantage, this paired board is quite static and our specific hand benefits from pot control and realizing its backdoor equity.

Turn Analysis

Betting the Ace is a reasonable deviation, though checking remains the range-wide preference. We've improved to top two pair, but the spade completion makes this a polarized spot where we need to be careful about over-valuing our hand.

River Analysis

Checking is the only viable play on this river. The fourth spade makes our two pair extremely vulnerable, as any single spade in the Button's range now beats us. **Board:** The 7s is a disastrous card for our specific holding. It completes the four-flush and a possible straight (45), meaning we are now losing to a massive portion of the Button's calling range. **Ranges:** Our hand has plummeted in relative strength. Button has many flushes like JsTd or 4d4s, while we are now primarily a bluff-catcher. Betting would only get called by better and fold out the air we beat. **Math:** With 53% equity against the Button's overall range, we have enough to check-call small bets, but we cannot value bet into a range that is 39% flushes. --- > **Takeaway:** When the board develops a four-flush, your non-flush value hands must shift into check-call or check-fold modes.
