When turning missed draws into river bluffs, use large or overbet sizings to fold out condensed pairs instead of small bets that offer easy calls.

Flop Analysis

Checking back is standard here — this wet, connected texture connects well with the small blind's defending range, and Ace-high without a spade has plenty of showdown value to check.

Turn Analysis

Stabbing as a semi-bluff after picking up an open-ended straight draw is viable, but the small sizing fails to leverage the turn card.

Note: Sizing is too small for a semi-bluff on a connected board; larger sizings (around 5.0BB to 7.5BB) put much more pressure on villain's weak pairs.

River Analysis

Checking back is the primary play with Ace-high after our draw misses. When bluffing here, our sizing must be polarized rather than half-pot. **Ranges:** The small blind's range after check-calling the turn is heavily condensed around one-pair holdings like 8x, 7x, and weak Tx. A 5.0BB bet offers 3:1 pot odds, giving villain an effortless call with virtually any pair. **Sizing:** To fold out stubborn third or fourth pairs, solver strictly utilizes overbets (around 12.5BB) when choosing to bluff this river. A half-pot sizing targets an almost nonexistent folding range and simply burns chips. --- > **Takeaway:** Do not bluff condensed one-pair ranges with mid-sized bets — either overbet to generate real fold equity or check back your showdown value.

Note: Betting half-pot with a missed draw into a condensed range runs directly into villain's calling station pairs without enough fold equity.
