Preflop and flop are fine, but the turn shove is an over-ambitious bluff that burns way too much money given stacks and board.
Flop Analysis
Calling flop with our gutshot and overcard is correct — we have plenty of equity, excellent price, and our hand is high in our continuing range even though it’s just a draw.
**Ranges:** SB 4‑bet c‑betting on this texture is still value/draw heavy (overpairs, TT–QQ, AK with backdoors, diamond combos), but our AQs with a gutshot and backdoor blockers sits comfortably ahead of SB’s pure bluffs and has solid equity versus value.
**Math:** We’re getting 4:1, needing ~20% equity; our gutshot plus overcard plus implied odds versus overpairs easily clears that threshold.
**Board:** The connected, two-diamond texture is dynamic and interacts strongly with SB’s range, so we don’t want to blow the pot up with a raise when our hand is more about realizing equity.
---
> **Takeaway:** When getting a great price with good but non‑nut equity, favour calling and realizing rather than turning a decent draw into a bluff.
Turn Analysis
Turn is where the hand goes off the rails: with only a gutshot and no fold equity guarantee, we should mostly check back; the huge all‑in overbet is a big EV punt against a strong, capped-but-resilient 4‑bet range.
**Ranges:** The paired 6 reduces SB’s value density slightly (fewer strong top-pair type combos), but SB still has many overpairs, Jx and full houses, while our hand is pure high-card plus gutshot — near the bottom of our range and better suited as a check.
**Board:** The pair on board and still-wet structure mean made hands are very sticky; this card doesn’t massively weaken SB’s calling range, so a huge bluff overbet mostly isolates us versus strong hands and boats.
**SPR:** With a shallow-ish pot-to-stack ratio for SB, any big bet we make commits them; shoving effectively 1.3–1.5x pot needs a very high fold rate, which SB’s range simply doesn’t provide here, especially at NL200 where 4‑bet pots are under-bluffed.
---
> **Takeaway:** In 4‑bet pots on paired, wet turns, don’t torch stacks by overbet-jamming weak draws — check and take your equity unless your bluff has strong blockers and credible fold equity.
Note: The massive turn shove with only a gutshot in a 4‑bet pot overestimates fold equity and risks far too many chips; checking back is much higher EV.
