- J♠ 9♥ 9♣
Preflop and flop are solid, but once the board pairs and connects, KK needs more pot control — especially on this river where shoving turns a bluff-catcher into a punt.
Flop Analysis
Betting is correct — we have a clear range and nut advantage on this paired, relatively dry board, and KK cleanly value-bets vs JJ, Tx, underpairs, and floats.
**Ranges:** UTG has more 9x and JJ, but our 3-bet range has many overpairs and strong Jx; KK sits in the upper-mid of our value, happily betting for protection and value versus hands like AQ, TT, 88.
**Board:** The paired 9s plus a single high card make the texture fairly static — no flushes and only some straight draws — so overpairs benefit from betting early while equity is clear.
**Sizing:** Solver prefers a larger 70–80% pot bet with KK to deny equity from overcards and gutshots and start stacking UTG’s Jx/TT; our ~55% sizing is slightly small but functionally fine.
---
> **Takeaway:** On dry paired boards where we have the overpair advantage, lean into a bigger c-bet size to push equity and simplify later streets.
Note: Bet sizing is a bit small; solver prefers a larger 70–80% pot bet with KK to push value and protection.
Turn Analysis
Turn is where strategy should pivot: solver wants us to check KK most of the time here, using it as a medium-strength showdown hand rather than piling money in on a now-volatile board.
**Board:** The T adds straight and flush-draw potential and improves a lot of UTG’s continuance range (JT, TT, Tx with draws), while we’re still just an overpair with a gutshot — our relative hand strength drops.
**Ranges:** After calling flop, UTG’s range is condensed around 9x, strong Jx, TT–QQ, and draws; our big turn bet mostly gets called by two pair+ and strong Jx, while worse pairs and floats start folding, which is bad for a hand in our “upper-mid” region.
**Plan:** With SPR ~1.7, checking keeps our range protected, realizes equity with KK+gutshot, and allows us to call reasonable bets on safe rivers; betting 2/3 pot forces a polarized river where KK is too weak to stack off but too strong to bluff.
---
> **Takeaway:** When a turn card shifts the range edge toward villain and makes the board more dynamic, overpairs should often check back instead of barreling big.
Note: Barreling large on the turn with KK on a now-connected board overplays a medium-strength value hand that solver prefers to check most of the time.
River Analysis
River is a clear check: KK is now just a bluff-catcher on a brutally good runout for UTG’s range, and shoving turns a decent SDV hand into a low-EV punt.
**Ranges:** UTG arrives here after calling flop and a big turn mainly with 9x, Tx, boats (JJ, TT, 99), and some straights; we beat only Jx and some overpairs that check-call, while our shove targets a very narrow set of worse hands that can realistically call.
**Board:** Double-paired J-9-T structure massively favors UTG’s flatting range versus our 3-bet range — they can have all suited 9x/Tx and more JJ/TT, while we’re capped below boats often; KK is nowhere near the top of our value on this runout.
**Math:** Effective shove is ~37.4BB into 87.5BB, risking 37.4 to win 87.5; we need villain to call with worse quite often, or fold a big chunk of their range. In practice, most of UTG’s calling range here is trips+ and straights, which crush us, while Jx and underpairs either fold or check behind.
---
> **Takeaway:** On river runouts that dramatically favor villain’s range, treat overpairs as bluff-catchers and check — betting big just isolates you against better hands.
Note: Jamming KK on this river is a major overplay — solver pure-checks, and the shove mainly gets called by hands that have us crushed.
