How to Play Heads-Up Poker: One-on-One Rules
How to play heads-up poker explained: the reversed blinds, who deals, the button-is-small-blind rule, and how one-on-one strategy differs.

Heads-up poker is poker played one-on-one — just two players, no one else at the table. The rules are standard Texas Hold’em with one important twist: the blinds are arranged differently, and the player on the button acts first before the flop but last on every street after it. Because you’re always in a blind and always in the action, you play far more hands than at a full table, which makes heads-up the fastest way to rack up experience.
The one rule that changes: the blinds
At a full table, the button is the last seat in the blind order and posts nothing. Heads-up flips this:
- The button posts the small blind.
- The other player posts the big blind.
This is the single most misremembered rule in poker, so it’s worth stating plainly. The dealer/button is the small blind. There are only two players and both are “in the blinds” every single hand — there is never a hand where you fold for free.
For the underlying logic of why the button matters so much, see the dealer button rules and the wider concept of table position.
Who acts first, street by street
The acting order also has a twist that trips up newcomers:
| Street | Acts first | Acts last |
|---|---|---|
| Pre-flop | Button (small blind) | Big blind |
| Flop | Big blind | Button |
| Turn | Big blind | Button |
| River | Big blind | Button |
So the button acts first before the flop but has position on every later street. That post-flop position — acting last, seeing what your opponent does before you decide — is a powerful, permanent advantage, which is why the button posts the smaller blind to balance it.
How a heads-up hand plays out
The flow is otherwise identical to any Hold’em hand:
- Post blinds — button posts small, opponent posts big.
- Deal two hole cards to each player.
- Pre-flop betting — button acts first.
- Flop (three community cards) — big blind acts first.
- Turn (fourth card) — big blind acts first.
- River (fifth card) — big blind acts first.
- Showdown — best five-card hand wins.
The button alternates every hand, so you swap between small blind and big blind on each deal. If the full sequence of streets is new to you, walk through it in how a hand of poker plays out.
Why heads-up strategy is different
Heads-up looks simple but plays hard. The reason is math: with only one opponent, most hands are ahead of a random hand.
- You must widen your range. Waiting for aces means paying blind after blind. Hands you’d fold at a nine-handed table — like king-seven or a low ace — become playable, even raises.
- Position is everything. With the button acting last on three of four streets, in-position aggression wins a huge share of pots.
- Aggression beats caution. Passive play bleeds chips through the constant blinds. Betting and raising to apply pressure is the winning default.
- Reads matter more. With one opponent, patterns emerge fast. Track how they react to bets and adjust every orbit.
A worked hand
You’re on the button with A♦ 7♣. In a full ring you might fold this. Heads-up, it’s a clear raise.
- Pre-flop: you post the small blind, then raise. Your opponent (big blind) calls.
- Flop: A♠ 9♥ 3♦. You’ve paired your ace. The big blind checks; you bet for value; they call.
- Turn: 4♣. They check again; you bet again; they call.
- River: J♠. They check; you check behind — a modest hand, no need to bet into a possible better ace.
- Showdown: they show K♦ 9♦ — a pair of nines. Your pair of aces wins.
Notice how position let you control the pot: acting last on every post-flop street, you always saw the check before deciding.
Where to play and practice
For beginners wondering where to play heads-up, the easiest starting point is a free play-money app or a home game against a friend — no stakes, all volume. Sit-and-go heads-up games online give structured, one-table matches. Because you see so many hands per hour, heads-up is one of the quickest ways to internalize betting rhythm and hand reading before you sit at a full table.
The takeaway
Heads-up poker is standard Hold’em for two players, with one big rule change: the button posts the small blind and acts first pre-flop but last afterward. You’re in every hand, so you play wide, aggressive, and position-aware. It’s demanding, but it’s also the fastest teacher in poker.

Frequently asked
How does heads-up poker work?
Heads-up is poker played between just two players. The button posts the small blind and acts first before the flop, then acts last on every later street. Otherwise the rules — deal, betting rounds, and showdown — follow standard Texas Hold'em.
Who posts the blinds in heads-up?
The player on the button posts the small blind, and the other player posts the big blind. This is reversed from a full-ring game, where the button is the last of the blind positions rather than the small blind.
Who acts first in heads-up poker?
Before the flop, the button (small blind) acts first. On the flop, turn, and river, the order flips — the big blind acts first and the button acts last, giving the button position on every post-flop street.
Is heads-up poker good for beginners?
Yes and no. The rules are simple and you play far more hands, which speeds up learning. But it's strategically demanding because you must play a wide range of hands and can't wait for premium cards.
