Heads-up for the title. You're on the button (the small blind) with K♥2♥.

Heads-up, on the button with K♥2♥. Best?

WhyRaise. Heads-up, hand values invert toward high cards and position: any king is strong, and on the button you act last on every post-flop street. K-2 is well above an average heads-up hand - folding it would be far too tight.
What happensYou raise; you'll have position the whole hand.  Raise far more heads-up.
Heads-up, K-2 is a clear raise - with only one opponent, high-card strength and position dominate, and most hands are well above average.

Heads-up, hand values swing toward high cards and position - fold far less and raise far more than at a full table.
