We missed a mandatory c-bet on the flop but correctly extracted value once we turned the nut straight.
Flop Analysis
Checking here is a significant miss. On paired, high-card boards, the preflop aggressor has a massive range advantage and should bet almost 100% of the time.
**Ranges:** We have all the strongest Kings (AK, KQ, KJs) and AA/QQ that BB lacks. Betting small forces BB to defend wide with marginal hands like 77-99 or weak J-highs that we dominate.
**Board:** The paired King texture is very static. Since it's difficult for BB to have a King, a small 33% pot bet generates high immediate fold equity while keeping their range wide enough for us to extract value later if we improve.

> **Takeaway:** On dry, paired high-card boards, use a high-frequency small c-bet to leverage your range advantage.
Note: Checking back is a mistake; this board texture demands a high-frequency small c-bet to capitalize on our massive range and nut advantage.
Turn Analysis
After checking back the flop, we turn the nut straight. While the solver leans toward checking to protect our range, betting for value is perfectly viable to build the pot.
**Ranges:** Our check on the flop 'caps' our perceived range, making this turn bet look like a steal. BB can still have many Kx hands that played check-call or slow-played, but we now beat all of them except rare full houses.
**Board:** The Queen is a double-edged sword; it completes our straight but also introduces a diamond flush draw and potential full houses (TT, QQ, KK). This makes checking back a high-frequency play to realize equity safely.
**Sizing:** The small 33% sizing is effective here. It induces calls from worse pairs (Tx, Qx) or draws that might have folded to a larger polar sizing after the flop went check-check.

> **Takeaway:** When you turn the nuts after checking back, a small bet can often induce 'curiosity calls' from opponents who think you are capping your range.
