Flop Analysis
Checking top pair on this dry, ace‑high 4‑bet pot board is exactly what the solver wants with A♣T♣ almost all the time.
The big leaks are flatting the 4‑bet OOP, then continuing vs turn raise and river jam with a dominated, medium-strength hand in a spot where villain is very value-heavy.
Checking top pair on this dry, ace‑high 4‑bet pot board is exactly what the solver wants with A♣T♣ almost all the time.
Betting turn with top pair + gutshot is fine, but the size is off; with this SPR we either check or use a larger, more committing bet rather than a tiny stab. **Board:** The 9 connects the middling cards and adds straight possibilities, but overall the board still smashes CO’s strong, condensed 4‑bet range more than ours. **Sizing:** Solver prefers a ~½‑pot bet with A♣T♣ when it does bet, because at SPR ~2 we want to put meaningful pressure and cleanly set up stacks, not leave a lot behind after getting called or raised. **Plan:** If we choose to bet, the line should be part of a clear plan to play for stacks vs worse Ax and strong draws, not a small probe that invites a raise from better hands. --- > **Takeaway:** In low‑SPR 4‑bet pots, either check or use a robust sizing; small block bets with medium strength hands just open the door to painful raises.
Note: Using a small turn bet with A♣T♣ instead of checking or betting the solver’s preferred larger size weakens our line and mis-shapes the pot.
Once CO raises the turn, A♣T♣ becomes the bottom of our value region and should fold; solver has this combo pure-fold despite the attractive price. **Ranges:** CO’s check‑back flop then small raise vs turn lead in a 4‑bet pot is extremely value‑dense: slowplayed sets, A9s/A8s, straights (T7s, 57s) and sometimes overpairs; bluffs are scarce because there’s little incentive to turn strong overpairs into bluffs at this SPR. **Math:** We’re offered ~3.4:1 (need ~23% equity), but vs a range that is ~60%+ value and whose value mostly dominates top pair, our realized equity with A♣T♣ is well below that threshold. **Plan:** Calling here with SPR <1 going to river effectively commits us to many bad river calls; folding keeps our 4‑bet pot range from over‑defending thin top pairs against raises. --- > **Takeaway:** In 4‑bet pots, turn raises are heavily value‑weighted; disciplined folds with dominated top pair are mandatory even when the raw pot odds look great.
Note: Calling the turn raise with A♣T♣ when solver folds this combo 100% badly over-defends a dominated, medium-strength hand against a very value-heavy line.
Checking river with A♣T♣ on the paired board is correct; our hand is now a bluff-catcher/two pair in a spot where CO holds the nut advantage and we shouldn’t value-bet.
Facing the river shove, two pair A♣T♣ is not strong enough to call; in a 4‑bet pot on this paired, connected board CO’s range is overwhelmingly trips+, straights, and boats. **Ranges:** After CO 4‑bets pre, checks flop, raises turn, then shoves river, they are extremely uncapped while we are capped around top pair / weak two pair; natural value includes 8x full houses, sets, and the few straight combos, while missed bluff candidates are limited. **Math:** We’re getting ~3.4:1 and need about 22.5% equity, but given the line and preflop construction our hand’s actual equity vs CO’s shove range at NL200 is far lower, making this a clear fold despite the pot odds. **Bluff-Catcher:** Two pair here functions as a bluff-catcher because it loses to almost all nutted holdings; in these range‑disadvantaged spots we must overfold bluff‑catchers against big, polar bets. --- > **Takeaway:** In 4‑bet pots, when a tight, uncapped range barrels check–raise–shove on a scary paired runout, even strong-looking two pair should usually hit the muck.
Note: Calling the river shove with A♣T♣ as two pair in a 4‑bet pot versus a polar, value-heavy line is a large -EV call; this is a fold even with good pot odds.
