We should use our range advantage to bet the flop and turn rather than checking down and folding to a small probe.
We should lean toward betting here. As the 3-bettor on a King-high board, we have a significant range advantage and should use our bottom pair to deny equity from Villain's overcards.
Note: Checking is too passive; solver prefers betting small (33% pot) or medium (50% pot) to leverage our range advantage and protect our vulnerable pair.
After checking the flop, we should look to seize the initiative on this brick turn. Our hand is a prime candidate for an overbet bluff or a small protection bet.
Note: Checking again allows Villain to realize equity for free; an overbet here targets Villain's capped range of middle pairs and gutshots.
Folding to this tiny 31% pot bet is a significant error. We have bottom pair with the best possible kicker and are getting incredible odds to see a river. **Math:** We need only 19.3% equity to call. With our pair of 4s, we have nearly 30% equity against Villain's range, which includes many gutshots like AQo or ATo that we currently beat. **Ranges:** Villain's range is condensed after checking back the flop. They will have many middle pocket pairs (TT-66) and gutshots that are stabbing at the pot now that we've shown weakness twice. **Blockers:** Our Ad is a double-edged sword; it blocks some of Villain's AQ/AT bluffs, but we still have enough raw equity to continue against a sizing this small. --- > **Takeaway:** Don't over-fold to small 'probe' bets when you have a made hand and excellent pot odds, especially after the action has gone check-check.
Note: Folding is a massive over-fold; we have a pair and are getting over 4:1 odds against a range that contains many bluffs.
