While we have the nut flush draw and a straight draw, we must fold when SB check-raises all-in on a board that already completed many strong hands.
Raising here is a significant overplay. We have almost no equity when called, and this board texture heavily favors the Small Blind's range of high cards and pairs.
Note: Raising with just a backdoor flush draw is too aggressive; calling or folding is preferred as we lack the equity to sustain pressure.
After our flop raise is called, we pick up massive equity on the turn. Betting is correct to maximize pressure and realize our equity with a huge combo draw. **Board:** The 6s is a dynamic card that completes straights (95, 54) and flushes. It gives us the nut flush draw and an open-ended straight draw, making it a perfect semi-bluff candidate. **Ranges:** We have a nut advantage here as we can hold more 59s and 54s than the SB. Betting 70% pot forces their Kx hands into a difficult spot while we still have over 40% equity against their entire range. --- > **Takeaway:** When you turn a massive combo draw after showing strength, continue betting to keep the initiative and maximize your fold equity.
Despite having the nut flush draw, we must fold to the jam. The SB's check-raise represents a range that is almost entirely flushes or straights, leaving us with insufficient equity to call. **Math:** We need roughly 26% equity to call the shove. Against a range of made flushes and straights, our As5c only has about 21% equity because many of our straight outs are also flush outs for the opponent. **Blockers:** Holding the As is a double-edged sword. While it means we have the best draw, it also blocks the bluffs we want the SB to have (like AsX air). Their line is extremely polarized toward value that already beats us. --- > **Takeaway:** Don't go broke on a draw when the board is already 'wet' enough for your opponent to have many completed hands that dominate your outs.
