- 2♥ 7♣ 6♥
While our overpair is strong, the SB's massive river check-shove on a paired board is heavily weighted toward nutted hands like boats or straights.
Flop Analysis
Betting small is acceptable, but checking is the preferred baseline in a three-way pot to protect our range on a texture that connects well with the callers.
**Position:** Being out of position against the SB but in position against UTG+1 creates a complex dynamic. In multiway scenarios, the burden of defense is shared, but the preflop raiser should generally play more cautiously as the presence of a third player significantly reduces our equity.
**Ranges:** SB's cold-call and UTG+1's flat-call ranges are dense with mid-pairs (88-55), suited connectors (98s, 87s, 76s), and heart draws. While we have an overpair, we don't have a massive nut advantage on a 7-6-2 board.
---
> **Takeaway:** In multiway pots, lean toward checking even with strong one-pair hands to realize equity and avoid being squeezed.
Turn Analysis
The board pairing the deuce is generally a safe card for our overpair, though it does improve SB's specific A2s or 22 holdings.
**Sizing:** We chose a medium sizing, but this is a prime candidate for an overbet. By using a 125% pot sizing, we put maximum pressure on SB's 7x, 6x, and heart draws while polarizing our own range.
**Ranges:** SB's range is now quite condensed after calling the flop. They likely hold a 7, a 6, or a draw. Since we block J7s and JJ, we are mostly targeting hands like 88-TT or A7s that are indifferent to the bet size.
---
> **Takeaway:** On paired turns that don't change the board's hierarchy, use large sizings to maximize value from capped calling ranges.
River Analysis
The river is a blank for most of the range, though 45s does complete a straight. We have a mandatory value bet here.
**Sizing:** Again, the solver strongly prefers a massive overbet (125% pot). Our overpair is effectively the nuts against SB's bluff-catchers (7x, 88-TT), and we want to maximize the price they pay to see a showdown.
**Board:** The 3c doesn't complete the flush, which is excellent for us. While 45s is a possible straight, SB has far more 7x and mid-pairs that will struggle to fold to a large bet.
---
> **Takeaway:** When the draws miss and you hold a top-of-range value hand, don't be afraid to use polarized overbet sizing.
River Analysis
This is a disciplined and correct fold. At NL200, a check-call, check-call, check-jam line on a paired board is almost never a bluff.
**Math:** We are getting 3.4:1 and need about 23% equity to call. However, SB's range here is incredibly narrow, consisting of 77, 66, 22, and occasionally 45s. It is very difficult to find enough bluffs in SB's range to make this a profitable call.
**Exploits:** At these stakes, players rarely turn missed heart draws into a massive all-in check-raise on the river. This line represents extreme strength, usually a full house that was 'trapping' on the turn.
---
> **Takeaway:** When a passive opponent suddenly jams for 5x the pot on the river, their range is almost exclusively nutted; overpairs are easy folds.
