Heads-up
Poker between exactly two players, either as its own format or at the end of a tournament when two remain. Hand values shift a lot: any pair or ace is strong, and aggression matters more than card strength.
Frequently asked questions
What does heads-up mean in poker?
Two players, either as a whole format — a heads-up match or the end of a tournament — or simply a pot that two players contest after everyone else folds.
How do the blinds work heads-up?
The button posts the small blind and acts first before the flop, then last on every later street. This reverses the usual full-table arrangement and catches out players reaching heads-up for the first time.
Why are heads-up ranges so wide?
Because you are in a blind every hand, so folding constantly is not an option — strong players raise the majority of their buttons and defend most big blinds. Position matters more than cards, and the format rewards aggression and adjustment more than any other.
