Best play: Raise / 3-bet
Why
Folded to hero on the BTN with K♦9♦, this is a first-in open, not a 3‑bet. K9 SUITED sits comfortably inside the very wide BTN RFI range: the button opens roughly half its hands, and a suited king with a flush draw, top-pair potential, and a dominating kicker over the blinds is a clear open-raise. Folding here would surrender a hand that prints from the most profitable seat at the table.
Key idea
The BTN opening range is the widest at the table; suited kings like K9s are automatic first-in opens, never folds.
Common mistake
Misreading K♦9♦ as offsuit and folding, or calling it a 3‑bet; it is a routine BTN open-raise.
