Why
Hero is BTN first to act with K7s at 65bb. The HU BTN opens roughly 80-100% of hands, so a suited king is a routine open with no hesitation. K7s clears the bar easily: a king is the second-highest card, the suit gives flush playability, and the depth at 65bb rewards a hand that can flop top pair or a flush draw against a BB that defends very wide. Limping forfeits fold equity and initiative; folding is far too tight for a HU button. Raise (open) is the standard EV-max steal.
Key idea
Suited broadway-adjacent hands like K7s are pure auto-opens on the HU button. The king blocker and flush/top-pair potential mean you are never close to folding; the only debate is sizing, not whether to raise.
Common mistake
Folding K7s out of full-ring habit. At a HU button you are giving away a clearly +EV open and the postflop edge a king-high suited hand holds over the BB defending range.
