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
On J T 7 4 3 (rainbow-ish, no flush) your A♥8♥ missed everything — it is ace-high with no pair and no showdown value against a BTN that called two streets. As the SB leading first into a board that connects far better with your perceived strong range (sets, two pair, straights like 98/JT), an overbet of 120% pot is the polar bluff: you turn a hand that wins almost nothing at showdown into pressure on the BTN's many capped one-pair hands.
Key idea
A pure bust with no showdown value is the ideal candidate for a polar overbet bluff: you risk a hand that wins nothing by checking, and the large size maximizes fold equity against capped one-pair holdings.
Common mistake
Checking ace-high here and giving up: you forfeit fold equity over a hand that almost never wins at showdown, when this exact hand is a textbook river bluff in your leading range.
