preflop Analysis
ATo is a standard SB 3-bet versus the BU open at 100BB. We deny position, pressure the BU’s wide opening range, and retain strong blocker value when called.
We used a sound mixed flop c-bet and a strong turn barrel, but the river shove is only profitable if a twice-calling range can still fold enough pairs.

Checking is the main line, but the large c-bet is a fully acceptable mixed choice and earned the full grade. Our ace-high has showdown value, so checking often keeps Villain’s misses available while avoiding a bloated pot against pairs. **Ranges:** Villain arrives with many two-overcard hands, but also pairs and some strong made hands; our A-high only beats the unpaired portion. The Ah removes some of Villain’s ace-high continues, making a bluff less attractive than it first appears. **Sizing:** When we do bet, the large size creates immediate pressure on air and supports a polarized range alongside overpairs. It is not a value bet: worse hands rarely pay, while pairs continue. --- > **Takeaway:** With ace-high in a 3-bet pot, check most often—but use the larger c-bet selectively to pressure missed overcards.
The turn barrel is correct. We still have only ace-high, but the shallow SPR makes fold equity valuable and charging Villain’s unpaired hands is better than allowing a free river. **Ranges:** Villain has many ace-high hands and middle pairs after calling the flop. The medium bet folds much of the former while making pocket pairs face an uncomfortable continue-or-raise decision; sets and top pair remain the hands we must respect. **Plan:** This bet is a bluff, not protection with a made hand. Once called, our river range must be prepared to follow through selectively because we are very rarely ahead of a pair. --- > **Takeaway:** At low SPR, keep barreling ace-high when enough unpaired hands can still fold and free cards favor Villain.
The river shove is a pure fold-equity play: our ace-high beats only Villain’s remaining unpaired hands, while any pair has us beaten. With no precise river strategy supplied, the key question is whether the flop-and-turn caller can release enough one-pair hands to a short-stack shove. **Ranges:** After two calls, Villain’s range is materially stronger than it was on the flop and contains many pairs. The J does not give us a made hand, so this line depends entirely on representing strong value credibly and making those bluff-catchers fold. **Math:** The all-in is small relative to the pot, so it needs relatively few folds in isolation. But small river shoves also receive wider calls, making this a thin bluff candidate against a range that has already continued twice. --- > **Takeaway:** A river bluff can need only modest fold equity, but double-call ranges are often pair-heavy enough that ace-high should give up more often.
