Why
Final board J♠ 7♣ 4♦ T♦ 3♠ is uncoordinated with no flush and no completed straight; the BTN's range is Jx, Tx, underpairs and busted draws. Hero holds J♦J♣ = top set (three jacks), essentially the nuts — only the rare straight could beat it and none is on this board. Leading the overbet OOP is the textbook polar value play: hero gets max value from Jx/Tx and the occasional hero-call while denying free showdowns to the capped BTN.
Key idea
With top set on a dry river, overbet-leading OOP maximizes value — don't slow-play the near-nuts and let a capped opponent off the hook.
Common mistake
Checking top set to "keep bluffs in" — OOP you forfeit huge value, since the capped BTN will often check back and you miss two streets of profit.
