Best play: Overbet 120% pot
Why
River: K‑T‑7‑6‑2 with three spades on board, but hero holds J9 of diamonds, so this is bare Jack-high — no pair, no straight (no Q or 8 to fill 9‑T‑J), no flush. Against a capped SB range that has checked twice and is full of give-ups and busted spade/straight draws, hero has zero showdown value, so the overbet runs as a pure polar bluff to fold out the SB's weak made hands and missed draws. Checking simply surrenders the pot with a hand that can never win at showdown.
Key idea
On the river a hand is either value or a bluff — there is no draw left. Jack-high with no showdown value belongs in the bluff bucket, and against a capped range the overbet maximizes fold equity.
Common mistake
Treating J9 as if it still has 'outs' or straight/flush draws — on the river the hand is final and Jack-high can only win by betting.
