Defend A2s pre, but once we miss on a coordinated board we should mostly just fold to pressure instead of floating and getting to ugly turns.
Checking range from the big blind on this connected mid board is correct — BU has the range and nut advantage, and with just ace‑high plus a backdoor flush draw we belong firmly in the check bucket. Leading here would over‑expose our weakest holdings and make our range too face‑up when we check later streets.
Facing the flop c‑bet and SB call, our ace‑high with only a backdoor flush draw is meant to mostly get out of the way; calling here over‑defends the bottom of our range and puts us in nasty turn spots with low equity and poor realization. **Board:** This 9‑8‑7 rainbow configuration is very draw‑heavy and smashes both BU’s and SB’s calling ranges; most of the money will be made by real pair+draw hands and strong draws, not naked ace‑high. Our hand has only backdoor equity and no made strength, which is fragile in a multiway pot. **Math:** We are getting ~4:1, so we need about 20% equity, which our hand technically has versus BU’s betting range; but multiway and out of position, we realize that equity poorly because many turn cards force us to fold, and we rarely get to showdown when we do hit a weak top pair with a bad kicker. **Ranges:** Once BU bets and SB calls, both ranges are weighted toward at least a pair, strong draws and some overpairs; if we continue, we mostly hope to bluff later or spike very specific runouts, which is not what this combo is for. Solver prefers that this hand mostly fold and occasionally come in as a bluff‑raise, using the Ac as a blocker and leveraging fold equity instead of passively calling. --- > **Takeaway:** Even with good pot odds, ace‑high with only backdoor potential should usually fold multiway on a very coordinated board after bet and call.
Note: Calling the flop c‑bet multiway with bare ace‑high and only a backdoor flush draw is too loose; this combo should mostly fold (or occasionally bluff‑raise) rather than float.
After both players check to us on the paired turn, the pool‑wide optimal strategy is to introduce some leading from our range because ranges that defended the flop now have a clear advantage; with this actual hand (still just ace‑high with no draw), though, checking is completely reasonable while stronger hands and better draws do the betting. **Ranges:** The paired 7 significantly reduces BU’s nutted combinations while improving many of our flop‑defend hands (trips, full houses, strong 9x/8x), which is why range wants to stab small at some frequency, but trashy hands like A2 suited without hearts still function best as check‑folds versus big aggression. **Plan:** By checking this specific combo, we keep our betting range stronger and avoid bloating the pot with a hand that will almost never continue profitably versus a bet; if BU checks back, we can consider bluffing some rivers, but mostly we expect to fold facing sizeable turn action.
Folding turn versus BU’s sizable bet with only ace‑high and no draw is mandatory — we’re up against a range that is heavily weighted toward at least a pair or better on this paired, draw‑rich board, and we don’t have the equity or implied odds to continue. The earlier loose flop call forced us into this tough spot; once here, though, the fold is correct.
