Getting over 3.5:1 pot odds, folding the nut flush to a small check-raise is a critical blunder despite the paired board.

Flop Analysis

Auto-played to reach this drill spot — you didn't act here, so it isn't scored.

Turn Analysis

Stabbing small after SB checks twice is correct — it targets middle pairs and hands with a single spade without blowing SB off their marginal holdings.

River Analysis

Targeting worse flushes and sticky pairs makes this a clear value bet, though sizing up toward two-thirds pot or an overbet extracts maximum value from SB's calling range.

River Analysis

Folding the nut flush here is a severe error. We only need to be good a fraction of the time against this small raise, and our hand sits near the very top of our distribution. **Math:** Facing a raise to 11.8BB, we must call 7.3BB to win a 25.3BB pot, requiring just 22.4% equity to break even. **Ranges:** While the paired board introduces full houses like 66 or QQ into SB's range, SB also check-raises lower flushes such as JsTs, trips like Ac9c, and occasional bluffs. We beat everything except full houses and quads, making a fold far too exploitable. --- > **Takeaway:** Never fold the nut flush to a small river raise when getting better than 3.5:1 pot odds.

Note: Folding the nut flush getting phenomenal pot odds surrenders massive EV; this is a mandatory call despite the paired board.
