Flop Analysis
Checking range here is correct – this connected, low board slightly favors BU’s flatting range and our specific hand is pure give‑up with no immediate equity.
Line is solid until the river, where overbetting a non‑nut straight on a super-straighty board burns EV versus both GTO and population.
Checking range here is correct – this connected, low board slightly favors BU’s flatting range and our specific hand is pure give‑up with no immediate equity.
Turn check is fine and well within the mixed strategy; with only a gutshot and no pair we mostly realize equity rather than semi‑bluff into a still-uncapped BU range.
We arrive on the river with a straight but without the nut advantage on an already straight-completed board, so the solver wants us to mostly check and sometimes use a small block bet, not overbet. **Ranges:** Both ranges contain many straights here, but BU has all the 9x and some Tx combos that make higher straights, while most of our high-card-heavy opens just end up on the board straight – we’re strong but not polar enough to overbet for value. **Board:** The runout makes a straight using only the board, which drastically compresses value and turns a lot of “strong” made hands (sets, two pair) into bluff-catchers; large bets should be reserved for hands clearly above the board or for carefully chosen bluffs. **Sizing:** Solver prefers check ~70% and small 0.3x pot bet ~30%; our 1.5x pot overbet isn’t in the strategy tree and functions as a bluff/polar sizing in a spot where we mostly chop and occasionally run into higher straights, so we risk a lot to win a pot that rarely gets better hands to fold or many worse hands to call. --- > **Takeaway:** On boards where the board itself makes a strong hand and we don’t hold the nut advantage, lean on checks or small bets, not big polar overbets.
Note: River overbet with a non‑nut straight on a board-straight texture ignores that we mostly chop and have limited fold equity versus better, making check or small bet clearly higher EV.
