Best play: Overbet 120% pot
Why
Turn, board Q‑8‑4‑2 (turn the 2 of spades). Hero's A‑5 of diamonds is ace-high with no pair, but holding the ace blocks the BB's strongest Q-x and A-x value while equities are still live. Against a capped checking range an overbet applies maximum pressure as a polar bluff, folding out the many weak pairs and unpaired hands the BB has given up with; the A blocker makes this a clean bluffing candidate.
Key idea
On the turn, ace-high air with the right blocker is a fine overbet bluff against a capped range, because folds are still cheap to buy and you remove the opponent's value combos.
Common mistake
Checking back ace-high on the turn out of fear, surrendering the fold equity that the blocker and capped range make so profitable.
