Best play: Bet 40% pot
Why
Turn (Q‑8‑4‑2). SB vs BTN, hero is out of position and leads first into a capped BTN range. A‑5 here is ace-high with a wheel gutshot (a 3 completes 5‑4‑3‑2‑A) plus the A-diamond high card; the two spades belong to the board, hero holds none, so there is no flush draw. A small 40% lead bets denies equity to worse high cards and backdoors while keeping the overbet for stronger hands.
Key idea
On the turn an OOP small lead lets ace-high-with-a-gutshot deny equity cheaply while the strong part of the range carries the overbet size.
Common mistake
Treating the two board spades as hero's flush draw; hero holds no spade, so this is ace-high, not a draw.
