Use your range advantage to c-bet small on Ace-high boards, and don't be afraid to barrel draws that block the nuts.
While checking is a viable mix, this is a prime spot to c-bet small. We have a massive range advantage on Ace-high textures, and our hand has excellent semi-bluff potential with a gutshot and backdoor flush draw.
Note: Checking is acceptable but betting small (33% pot) is preferred to capitalize on our range advantage and fold out BB's air.
After checking the flop, the turn is a mandatory stab. The 6s is a dynamic card that completes the flush, but it also pairs the board, which favors our range as the preflop aggressor who can hold more 88/AA/A6s.
Note: Checking again is a significant miss; we should be stabbing here to deny equity and represent the flush or trips.
Once we check and face a bet, we have to let it go. Our equity has plummeted on this board, and we don't hold a spade to continue as a bluff-catcher. **Ranges:** BB's range is now very strong, containing many flushes (Kxs, QTs) and trips (6x) that we simply cannot beat with high card. Our range still has plenty of better hands to defend with, like Ax or flushes of our own. **Math:** We need 19% equity to call, but we only have about 16%. Without a spade in our hand to block the nut flush, calling is a losing play in the long run. --- > **Takeaway:** When you miss your draw and the board gets significantly wetter, don't feel obligated to defend just because you have a gutshot.
