Flop Analysis
We have flopped a King-high straight on a very dynamic board. While checking is the range-wide preference to protect our weaker hands, betting small is a high-frequency mix for this specific combo to build the pot immediately.
On a wet board where you have a strong but non-nut straight, prefer calling raises to keep Villain's bluffs in and avoid isolating yourself against the nuts.

Raising here is a significant error. We have the second-best possible straight, but by 3-betting, we essentially force CO to fold all their bluffs and weaker value while only continuing with the nut straight (AK) or sets that have huge redraw equity. **Ranges:** CO's raise represents a polarized range of sets (TT, JJ, QQ), two pairs (QJ, JT), and the nut straight (AK), along with spade draws. By raising, we isolate ourselves against the top of that range, specifically AK, which makes up 22% of their continuing range. **Blockers:** Our Kc is a double-edged sword; it blocks some of Villain's K-high straight bluffs but also blocks hands like KcQc or KcTc that might have called a call but fold to a 3-bet. **Plan:** Calling is much higher EV. It allows CO to continue barreling with semi-bluffs like AsXs or overplayed two pairs. We can then evaluate the turn, especially on bricks, to maximize value from their air. --- > **Takeaway:** When you have a strong but non-nut hand on a coordinated board, calling a raise is often better than 3-betting to keep your opponent's range wide and avoid running into the nuts.
Note: 3-betting the flop with the second-nut straight is overplaying the hand; calling keeps Villain's bluffs in and prevents you from being jammed on by the nut straight.
