AQo CO on J86fd: Commit Turn, Not River

Flop Analysis

Using the small flop c‑bet with our backdoor‑heavy high card is perfectly fine and lines up well with a range strategy that leans toward checking overall. **Ranges:** Both players have strong overpairs and top pairs; our 4‑bet range is more polarized (overpairs, some strong Jx, plus high‑equity bluffs like AcQx, AcKx), while BU is a bit more condensed around pairs and suited connectors that called pre. **Board:** This semi‑wet, two‑tone texture interacts well with BU’s suited 4‑bet calls, so the overall range wants to check a lot, but our specific hand gains from fold equity plus backdoor flush potential when we do bet. --- > **Takeaway:** On semi‑wet 4‑bet pots with shallow SPR, mixing small bets with our best backdoor overcards is a good way to realize equity and apply pressure.

Turn Analysis

Once we pick up the open‑ender with low SPR, the correct play is to shove rather than use a small block bet; our hand is a pure continue that wants full fold equity. **Ranges:** The king is much better for our 4‑bet range (AK, KK, some KQ) than for BU’s, so we hold a slight range and clear nut advantage while BU’s range is condensed around one‑pair Jx/8x/underpairs plus draws that called flop. **Math:** With ~69BB behind and ~63.5BB in the pot (SPR ≈ 1.1), jamming maximizes EV: our hand has decent equity when called and gains a lot from folds, whereas betting 16BB leaves ~53BB behind and under‑leverages our fold equity. **Plan:** Shoving now cleanly splits our range into strong value and high‑equity bluffs; the small turn bet followed by a river shove leaves us with an awkward, under‑repped line that gets called more often by one‑pair hands. --- > **Takeaway:** In low‑SPR 4‑bet pots, once we turn strong drawing equity, commit with a shove instead of nibbling and leaving a tough river spot.

Note: Turn should be an all‑in with our open‑ender at this SPR; the small 16BB bet sacrifices fold equity and creates an awkward river shove with a weaker perceived range.

River Analysis

After the draw bricks and we still only have ace‑high, shoving river is too ambitious versus a condensed, call‑heavy range; we should mostly give up once we’ve under‑bet the turn. **Ranges:** BU’s call flop / call small turn range is rich in Kx, Jx and pocket pairs that are very sticky to a river jam, while most of their obvious misses (like lower club draws) are a smaller fraction of the range at NL200 once they’ve called twice in a 4‑bet pot. **Sizing:** With an SPR ~0.55, the shove is theoretically a polar sizing, but our line (small flop, small turn) skews us toward medium‑strength hands in practice, so this jam over‑bluffs into a range that is not forced to overfold. **Plan:** The better plan was to commit on the turn; once we choose the small turn size and get called, river ace‑high should generally check and surrender, reserving big river shoves for lines where we were already polar on the previous street. --- > **Takeaway:** If we decline to jam our high‑equity bluff on the turn, we shouldn’t over‑correct by bluff‑jamming the river against a range that mostly has us beat.

Note: River shove with pure ace‑high into a condensed, showdown‑bound range is over‑aggressive after using a small turn bet; checking and giving up is higher EV.
