Flop Analysis
Checking top pair with a medium kicker is a high-frequency play to protect our checking range and control the pot size OOP.
While our top pair is strong enough to bet for value, we must fold when the river completes multiple draws and the opponent raises.

After the flop checks through, we can begin betting for thin value. The 3c is a blank for most of the BTN's range, though it does complete a wheel for exactly 45s. **Ranges:** BTN's flop check caps them significantly, often excluding AJ, sets, or strong flush draws that would bet for protection. We are ahead of their Jx, middle pairs like 88-TT, and spade draws. **Sizing:** The 1.8BB bet (33% pot) is ideal here. It keeps the range wide and allows us to get called by weaker pairs while maintaining a low-stress SPR for the river. --- > **Takeaway:** When the flop checks through, use small stabs with marginal top pairs to extract value from second-best hands and draws.
The Ks is a very dynamic river card. It completes the spade flush and the QT straight, but it also gives us a mandatory value bet with our top pair. **Board:** This is a 'scary' card that hits the BTN's calling range well, particularly hands like KJs or QTs. However, we still beat all Jx and smaller pocket pairs that BTN might call with one last time. **Sizing:** A 33% pot sizing is preferred to target the remaining Jx and Tx hands. Larger sizing risks isolating ourselves against the flushes and straights that just arrived. --- > **Takeaway:** Even when draws complete, don't go into a shell with top pair; bet small to target the 'sticky' part of the opponent's range.
This is a clear fold. When the BTN raises on this board, they are rarely bluffing, and our Ac9c blocks the few natural bluffs they might have had. **Ranges:** BTN's raise represents a very polarized and strong range, including flushes (As8s, As6s), straights (QTs), and two pairs (KJ). Our top pair is now just a bluff-catcher at the bottom of our value range. **Blockers:** Holding the Ac is actually detrimental here. It blocks hands like AcQs or AcTs that BTN might have turned into a bluff. We also don't hold a spade, meaning we don't block any of their value flushes. **Math:** We need roughly 26% equity to call. Against a range of flushes, straights, and two pairs, our top pair with a 9 kicker has almost zero equity, making this a high-frequency fold. --- > **Takeaway:** Don't pay off river raises on highly connected boards unless you hold a hand near the top of your range; top pair is rarely enough.
Note: Calling the river raise is a significant error; the BTN's range is heavily weighted toward flushes and straights on this runout.
