Flop Analysis
We must check our entire range here. The K-high texture heavily favors the 4-bettor's range, which is dense with AK and KK.
AA becomes a bluff-catcher on K-high boards in 4-bet pots; avoid thin river bets that invite polar jams.

While it feels counter-intuitive to fold AA to a small bet, we are at a massive range disadvantage. CO's 4-betting range is extremely King-heavy. **Ranges:** CO has all combos of KK and AK, while we have capped ourselves by calling the 4-bet. AA is effectively a bluff-catcher here, beating only QQ, JJ, and air. **Math:** We are getting 5:1, needing only 17% equity. However, if Villain is playing a tight, linear 4-bet range, our equity against their value is nearly zero, making this a disciplined fold or a aggressive raise-shove to maximize fold equity against their bluffs. --- > **Takeaway:** In 4-bet pots on boards that smash the aggressor's range, even AA must be played cautiously as a bluff-catcher.
Note: Calling is the lowest EV option; solver prefers folding due to the extreme range disadvantage on a K-high board.
Checking is correct. The 3s introduces a flush draw and straight possibilities (56s), but doesn't change the fact that we are behind Kx.
Betting here is a mistake. We are turning our hand into a target for a raise while rarely getting called by worse than a King. **Sizing:** The small 27% pot bet looks like a 'blocker' bet, but it actually re-opens the action for Villain to jam. If we bet, we want to target QQ or JJ, but those hands often check back anyway. **Board:** The 2h completes the wheel (A5s) and 56s. While these are few combos, they add to the list of hands that beat us along with AK and KK. --- > **Takeaway:** On the river, if your hand functions as a bluff-catcher, check-call or check-fold; don't bet and allow yourself to get blown off the pot.
Note: Betting the river is thin and invites a polar jam that puts us in a miserable spot; checking is the higher EV play.
Once we bet and get jammed on, we are in a mathematical prison. We need 17% equity to call, but Villain's range is now incredibly polarized. **Math:** Getting nearly 5:1, we only need to be right 1 out of 6 times. If Villain can ever turn a hand like QQ into a bluff or has missed spade draws, we have to click the button, even though we are likely beat by Kx or a straight. **Ranges:** CO's check on the turn often caps them, but a river jam represents the nuts (KK, AK, A5s). By betting small, we induced this action, making the fold nearly impossible despite the low likelihood of being ahead. --- > **Takeaway:** When you get 5:1 on the river with an overpair, you are usually priced in to call, even if the line feels like you're beat.
