Why
The 2♦ turn on Q♦9♣4♠ bricks the board and brings a backdoor diamond; in a HU single-raised pot the OOP player can attack the BTN's wide, capped continuing range with a check‑raise. Hero holds A♠8♠ — ace high, no pair, no real draw, but the A♠ blocks the BTN's strongest A‑Q value and ace-high floats. Check to the BTN and check‑raise as a semi-bluff/bluff: HU ranges are so wide and capped that pressuring with strong blockers and good removal generates fold equity against the many Q-x and floats that cannot withstand a raise.
Key idea
OOP check‑raise bluffs need blockers to villain's value and removal of their floats — ace-high with a key blocker fits in wide HU pools.
Common mistake
Check-folding ace-high here and never check‑raise bluffing, leaving the BTN free to barrel its wide capped range unpunished.
