Why
Hero is on the BTN with K♦9♦, a suited king, facing a single open (a facing-an-open spot, not a first-in). In position, flatting K9 SUITED beats 3-betting: it is too strong to fold and too dominated to want a 3‑bet pot, where it runs into AK/AQ/KK, but it flops top pairs, flush draws, and backdoors well enough to realize equity in position. Calling keeps villain's worse offsuit kings and broadways in the pot.
Key idea
K9s in position versus an open prefers flatting: strong enough to continue, but too dominated to relish a 3‑bet pot against the opener's value.
Common mistake
3-betting K♦9♦ for value, which mainly folds out worse and gets called by the AK/AQ/KK that dominate it.
