Best play: Bet 40% pot
Why
Final board J♠7♣4♦T♦3♠ is dry with no flush and only QT/98 completing a straight; the BB's range that checked the river to hero is capped on weak J-x, T-x and a large block of busted hands. Hero holds A♥8♥ which pairs nothing on this board, so it is ace-high air with no showdown value, beating only the missed hands it cannot get to pay. In position with the river checked through, a small 40% bet works as a low-risk blocker bluff: it folds out the many busted hands in the capped BB range cheaply, whereas checking simply gives up a hand that wins nothing at showdown.
Key idea
Ace-high air on a dry river prefers a cheap blocker bet to fold out a capped, bluff-heavy range.
Common mistake
Checking back ace-high that wins nothing at showdown instead of taking a cheap stab against a capped range.
