While our pocket pair is a mandatory call on the flop and turn, we must fold the river when the population under-bluffs a paired board.
Flop Analysis
Calling is mandatory here. We have a pocket pair that beats all of SB's air and we have excellent pot odds to see a turn.
**Math:** We are getting 4.3:1 on a call, requiring only 19% equity. Our hand currently has over 50% equity against SB's wide range.
**Ranges:** SB will c-bet frequently with two overcards like JdTh or AdQh. Our 44 is well ahead of these bluffs and only needs to avoid overcards to remain a strong bluff-catcher.
---
> **Takeaway:** With small pocket pairs, prioritize equity realization when facing small c-bets on low-textured boards.
Turn Analysis
Checking back is the standard play to reach showdown. While betting small is a solver-mixed option for protection, checking ensures we don't get check-raised off our equity.
**Board:** The 7d is relatively blank, though it does pick up some straight draw connectivity for hands like 5h4s or 6d5s.
**Plan:** By checking, we keep the pot manageable. We are looking to check-down or call small bets on most river bricks, as our hand retains value against SB's missed gutshots like Ah4h.
---
> **Takeaway:** In position with a marginal made hand, checking back the turn is the safest way to realize your showdown value.
River Analysis
This is a disciplined fold in practice. While the solver calls due to the high frequency of missed draws in SB's range, the population rarely bluffs this sizing on paired boards.
**Math:** SB is betting 1.2x pot (12.5BB into 10.5BB). We need 35% equity to call, but our pair of fours is now just a weak bluff-catcher that loses to any 9x, 7x, or pocket pairs like 55.
**Ranges:** SB's range is polarized between total air and strong value like trips (7s5s) or full houses. If SB isn't finding enough bluffs with missed spades or overcards, this call becomes significantly -EV.
**Exploits:** At these stakes, players rarely overbet the river as a bluff after checking the turn. This line usually represents a slow-played monster or a newly improved hand like trips.
---
> **Takeaway:** When the population uses large polar sizings on the river, lean toward folding marginal bluff-catchers.
Note: Calling a large overbet on the river is risky; population data suggests this line is heavily value-weighted, making a fold higher EV.
