Hero faces a polar river action after capped turn line.
What line avoids overbluffing while preserving value?
See the answer
Best play: Overbet 120% pot
Why
Final board K♦ 8♠ 4♥ 3♦ A♣: the river ace pairs hero and is a scare card for BB, whose capped range is mostly K-x, missed flush misses and busted broadways. Hero is IN POSITION with A♠Q♦ = top pair (aces) with the strong queen kicker, the top of what can credibly value-bet here while also holding an ace blocker. Overbetting is correct because the polar line gets called by worse K-x and second-pair value that cannot fold, and the ace card lets hero rep the nuts cheaply while charging the many one-pair hands maximum.
Key idea
When the river card improves you and scares the capped defender, overbet your strong top pair for max value.
Common mistake
Checking back a strong top pair on a river that scares the opponent, leaving value on the table.
