Best play: Overbet 120% pot
Why
River, board K-spade T-heart 7-spade 6-club 2-spade. With J-diamond 9-diamond you have busted air: no pair (your jack and nine miss the K‑T‑7‑6‑2 board), no straight (you would need both a queen and an eight, neither present), and no flush (you hold no spades). This is a pure no-showdown hand, exactly the kind of holding the polar overbet uses as a bluff against the capped BB. Firing 120% applies maximum pressure to the BB medium bluff‑catchers; with zero showdown value, betting is strictly better than checking and giving up.
Key idea
Pure no-showdown air is the correct candidate for a polar overbet bluff against a capped range — checking it back simply concedes the pot, whereas betting wins whenever the bluff‑catchers fold.
Common mistake
Checking back jack-high air to give up free showdown value it does not have, instead of betting where the capped BB must fold most bluff‑catchers.
