Q♠J♠ SB vs BTN, river on K♠ T♥ 7♠ 6♣ 2♠, 60 bb

Best play: Overbet 120% pot

Why

River, SB out of position on K-spade T‑7-spade-2-spade. Count the spades: K-spade, 7-spade, 2-spade on board plus Q-spade and J-spade in hand make five — hero has a King-high spade flush (K‑Q‑J‑7‑2 of spades), beaten only by an Ace-high spade flush. Against a capped BTN that rarely holds the lone better flush, this near-nut holding is a textbook polarized value lead, so the 120% overbet maximizes value from worse flushes, K-x and busted draws that pay a big sizing.

Key idea

Always recount the suits on the river: three board spades plus two spades in hand is a made flush, not Queen-high. A King-high flush against a capped range is a near-nut value hand that wants the biggest size.

Common mistake

Misreading the hand as Queen-high or a flush draw and checking it back, throwing away a near-nut flush's full value against a paying capped range.
