Calling an all-in bet with unimproved king-high gives away massive equity against a range packed with value and better bluffs.

Flop Analysis

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

Flop Analysis

Calling is preferred over raising here. An open-ended draw with king-high has plenty of equity to see turns cheaply without inflating the pot out of position. **Ranges:** When facing a third-pot c-bet, our hand has roughly 39% equity against broadway overcards and pocket pairs. Raising folds out the air we dominate and keeps in hands that dominate our draws. **Math:** Getting 3.5:1 on a call, we only need 22% equity to continue profitably, making a smooth call vastly higher EV than a bloated raise. --- > **Takeaway:** When holding good drawing equity with weak showdown value, take the cheap price rather than bloating the pot out of position.

Note: Raising inflates the pot out of position when calling gets fantastic pot odds to realize equity with an open-ended draw.

Turn Analysis

Checking is mandatory after our flop check-raise was called, keeping the pot manageable with an unimproved draw.

Turn Analysis

Calling here puts us in an awkward spot. With the pot ballooning and SPR dipping below 1, our strategy is polarized between shoving as a semi-bluff or letting it go. **Ranges:** Opponent's barrel range is concentrated in sets, straights, and strong top pairs. Against this distribution, our nine-high straight draw has limited clean outs. **SPR:** Facing a half-pot turn bet leaves us with less than a pot-sized bet behind for the river, severely crippling our implied odds when we do hit. --- > **Takeaway:** In low-SPR turn spots, avoid calling with naked draws—either apply maximum pressure by shoving or fold cleanly.

Note: Flatting out of position with an awkward stack size destroys our equity realization; we should either shove or fold.

River Analysis

Checking is standard for our overall range on this card, though our specific hand also has high frequency as an all-in bluff candidate to fold out weak pairs.

River Analysis

Calling an all-in shove with king-high is an extreme error. We hold pure high card on a board with completed straights and flushes, beating virtually nothing in villain's range. **Ranges:** Opponent is shoving for value with sets, straights, and flushes, mixed with bluffs like missed overcards. Even among bluffs, hands like ace-high naturally beat our king-high. **Math:** While getting over 3:1 pot odds requires only 24% equity, king-high has almost zero realistic showdown value against any barreling range. --- > **Takeaway:** Never bluff-catch with high card when missed bluffs still outkick you and value hands dominate the board.

Note: Calling an all-in bet with king-high is a major blunder; even opponent's missed bluffs often contain an ace.
