- 3♥ 3♦ 9♣
We play preflop and flop well, but once the board double-pairs and the flush comes in, AA has turned into a bluff-catcher and should fold to the huge river donk shove.
Flop Analysis
C-betting is mandatory with our overpair on this dry paired board, but solver wants an even smaller size than we used.
**Ranges:** After 4-bet/call, SB is condensed around strong pairs and big Broadway; we have a clear range and nut advantage with AA/KK and more overpairs in general, while SB has very little 3x/9x compared to us.
**Board:** The paired, rainbow, low card texture is extremely static — very few bad turns — so we don’t need a big protection bet; a small stab extracts from underpairs and 9x without bloating the pot.
**Sizing:** Solver chooses ~25% pot; our ~38% pot bet is still fine but slightly oversized, forcing worse hands to fold more often and making it tougher to value-bet three streets.
---
> **Takeaway:** On dry, paired boards in 4-bet pots with range advantage, use a small c-bet size even with big overpairs.
Note: Betting is correct, but sizing up above the solver’s small size gives up a bit of EV by over-protecting on a very safe board.
Turn Analysis
Once the board double-pairs, AA is no longer a clear value hand; solver mixes a lot and leans toward checking, so barreling again is okay but not mandatory.
**Board:** The turn pairing the 9 makes full houses and trips very realistic for SB, while most of SB’s underpairs have now improved in relative strength on this ultra-static runout and are happy to bluff-catch.
**Ranges:** Our range still has more overpairs, but SB’s continuing range after flop call is very pair-heavy; when we bet again, we mostly get called by hands that are two pair or better or stubborn pocket pairs, and we narrow out their air.
**Plan:** Checking lets SB stab with missed floats and protects our checking range, while keeping our stack-to-pot ratio low enough to call rivers on bricky cards; betting small, as we did, is reasonable but starts committing us versus a range that’s rarely folding.
---
> **Takeaway:** On a double-paired turn in a 4-bet pot, slow down with overpairs—check often and treat them more like bluff-catchers than slam-dunk value.
Note: Solver mixes here and slightly prefers checking; the small barrel isn’t a blunder, but it pushes AA toward a thin value line versus a very pair-heavy, sticky range.
River Analysis
By the river, with the king and third heart out and SB leading for a near-pot shove, AA is just a bluff-catcher and should fold versus this sizing and profile.
**Board:** The final card completes the heart flush and brings in top pair Kx; combined with the already double-paired board, SB now has many natural strong value hands (flushes and full houses), while our one-pair overpair hasn’t improved.
**Ranges:** SB’s line (4-bet call pre, check/call flop and turn, then huge river lead) is heavily biased toward strong made hands like heart-heart combos, Kx full houses, and 9x/3x full houses; thin value with single Kx or random bluffs is rare, especially from a low-aggression player.
**Math:** We’re getting about 2.9:1 and need roughly 26% equity; against a value-heavy range from a player who goes to showdown often and wins there a lot, AA almost never reaches that threshold.
---
> **Takeaway:** When a passive, showdown-happy opponent jams big on a scary river, treat even overpairs as bluff-catchers and fold if the value side of their range clearly dominates.
Note: Calling the big river donk shove with AA versus a value-heavy line and a stationy, low-bluff villain is a substantial mistake; folding is higher EV.
