Why
The 9♠ turn on A♣7♦3♥ pairs hero up on an ace-high board where the BTN's range is wide and ace-heavy but also full of missed broadways and air. As the OOP BB you hold K♦9♦ = second pair (the turned 9) with a backdoor diamond draw and the K kicker/overcard. Facing his turn bet you call: this is a bluff‑catch — against HU width his betting range contains plenty of worse pairs, busted draws, and pure air that you beat, and your second pair plus backdoor equity is enough to continue once, while raising would only fold out worse and isolate you against Ax.
Key idea
On an ace-high board in HU, a second pair with a backdoor draw is a fine one-street bluff‑catcher against a wide, air-rich betting range.
Common mistake
Folding second pair too readily to one turn bet, over-respecting an ace-high board in a spot where HU ranges are full of bluffs.
