Everything is fine until the river: top two is a value bet but should fold to a huge check‑raise in a 3‑bet pot.
C‑betting here is correct and we want a big size; with top pair top kicker in a 3‑bet pot our hand is strong enough to build the pot and deny equity to overcards.
Note: Betting half‑pot is fine, but the higher‑EV line is to use a larger 75–80% pot size with this combo to extract more from 9x and pocket pairs and punish overcards.
Checking back after the jack turns our hand into second pair is good; the card shifts some equity to villain and our hand now wants pot control more than another big value/protection bet.
Once the ace rivers and we improve to top two, betting for value is mandatory; a 60% pot bet is within the solver’s main mix even though a pot‑sized bet slightly edges it in EV.
Facing this huge river check‑raise, we should fold; in practice this line is heavily weighted to very strong hands and our top two pair does not have the equity the pot odds demand. **Ranges:** After we bet river, villain’s check‑raise range is overwhelmingly strong two pair and better — hands like ace‑jack and ace‑four that are very happy getting stacks in, with almost no pure bluffs showing up. Our hand is near the top of our value range but squarely in bluff‑catcher territory against this construction. **Math:** We are getting about 3.1:1 and need ~24% equity, but our hand has only around that versus villain’s raising range and the range as a whole is crushed (villain’s value is 100% of their range here). With almost no credible bluffs and a raise size around 1.7× pot, we are paying off a range that beats us far too often. **Plan:** In 3‑bet pots at NL200, we should treat big river check‑raises as massively under‑bluffed; bet our top two for value, but be disciplined and fold versus this kind of shove‑sized raise unless we have the nutty end like the wheel. --- > **Takeaway:** When we bet river and face a huge check‑raise in a 3‑bet pot, even strong hands like top two become folds because the raising range is almost all monsters.
Note: Calling the massive river check‑raise with top two pair is a large mistake; the pool almost never bluffs this line and our equity versus such a value‑dense range is too low.
