This guide focuses on betting order only — who acts first on each street and why the sequence changes. For full rules from deal to pot award, see Texas Hold'em Rules for Beginners.
Texas Hold'em action order at a glance
In Texas Hold'em, action order is the sequence in which players fold, check, call, bet, or raise. The order changes by street:
| Street | Who acts first | Who acts last (if still in the hand) |
|---|---|---|
| Preflop | First seat left of the big blind | Big blind |
| Flop | First active player left of the button | Button |
| Turn | First active player left of the button | Button |
| River | First active player left of the button | Button |
The key takeaway: preflop action starts left of the big blind, but postflop action starts from the small-blind side. The button acts last after the flop, which is why position is so valuable.
How many betting rounds are there?
Texas Hold'em has four betting rounds (streets): preflop, flop, turn, and river. Each round uses the same actions — fold, call, raise, check, or bet — but who acts first changes depending on the street.
Key positions you need first
| Position | Symbol | Role |
|---|---|---|
| Dealer (Button) | BTN / D | Marks where dealing starts. Acts last post-flop — the most powerful position. |
| Small Blind | SB | Sits left of the button. Posts half the minimum bet before cards are dealt. |
| Big Blind | BB | Sits left of the small blind. Posts the full minimum bet before cards are dealt. |

Setup before any action: the button and blinds
Before cards are dealt, two things define the table:
- Dealer button (BTN): marks the nominal dealer and moves one seat clockwise after each hand.
- Blinds (SB / BB): forced bets posted before hole cards are dealt.
The player left of the button posts the small blind (SB). The next player posts the big blind (BB). In a 5/10 game, SB posts 5 and BB posts 10 — live money in the pot before anyone looks at cards.
Blinds are posted only preflop. They are not paid again on the flop, turn, or river.
Preflop action order
Each player receives two hole cards, then action begins with the first player to the left of the big blind. In a full 6-max game, that first seat is UTG (Under the Gun).
Preflop action order by table size
Short-handed games remove early positions. The first player to act is always the first seat left of the big blind.
| Players | Positions in play | First preflop action |
|---|---|---|
| 2 (heads-up) | Button/SB, BB | Button (posts SB) |
| 3 | BTN, SB, BB | BTN |
| 4 | CO, BTN, SB, BB | CO |
| 5 | MP, CO, BTN, SB, BB | MP |
| 6 | UTG, MP, CO, BTN, SB, BB | UTG |
In a 6-max hand the usual order is: UTG → MP → CO → BTN → SB → BB. For what preflop means strategically, see What Is Preflop in Poker?
Preflop rule to remember: Action moves clockwise, starting left of the big blind and ending with the big blind (if there is no raise) or when all remaining players have called the highest raise.
The big blind gets a special privilege: if no one raised before action reaches them, they may raise — the big blind option — or simply check and see the flop.
Postflop action order (flop, turn, river)
After the flop, turn, and river, betting starts with the first active player to the left of the button. In most cases that is the small blind if still in the hand. If the SB folded preflop, action starts with the next active player — often the BB, then UTG, and so on.
The button acts last on every postflop street if still in the hand.
Example: 6-max postflop order
If all six players see the flop, the usual order is:
SB → BB → UTG → MP → CO → BTN
If SB folded preflop, skip SB:
BB → UTG → MP → CO → BTN
If both blinds folded, start from UTG:
UTG → MP → CO → BTN
Round-by-round notes
- Flop: Three community cards are dealt. If no one has bet yet, the first active player may check or bet — unlike preflop, where blinds create a bet to call.
- Turn: The fourth board card is dealt. Betting order is identical to the flop.
- River: The fifth and final board card is dealt. Same order again. After river betting, remaining players go to showdown if needed.
At showdown, the last player to bet or raise on the river shows first. If no one bet on the river, the player closest to the left of the button shows first.
Full hand flow: action order on every street
| Step | Street | What happens | Action order |
|---|---|---|---|
| 1 | Setup | Button and blinds are set | SB and BB post blinds |
| 2 | Preflop | Hole cards dealt | UTG → MP → CO → BTN → SB → BB |
| 3 | Flop | Three board cards dealt | SB side → … → BTN |
| 4 | Turn | Fourth board card dealt | SB side → … → BTN |
| 5 | River | Fifth board card dealt | SB side → … → BTN |
| 6 | Showdown | Hands revealed if needed | N/A |
Heads-up action order (2 players)
In heads-up Texas Hold'em, the button and small blind are the same player. That seat posts the small blind and acts first preflop. The other player is the big blind.
| Street | Who acts first | Who acts last |
|---|---|---|
| Preflop | Button (posts SB) | Big blind |
| Postflop | Big blind | Button |
This confuses many beginners because the button — normally the best seat — acts first before the flop in a two-player game.
Preflop vs. postflop: quick comparison
| Topic | Preflop | Postflop (flop, turn, river) |
|---|---|---|
| First to act | Left of big blind | Left of button (first active player) |
| Last to act | Big blind (if still in) | Button (if still in) |
| Blinds | SB and BB post forced bets | No new blinds |
| Information | Only hole cards and prior action | Hole cards plus board cards |
What actions are available on each street?
| Situation | Available actions |
|---|---|
| No bet yet | Check or bet |
| Facing a bet | Fold, call, or raise |
| Facing a raise | Fold, call, or re-raise |
You cannot check if someone has already bet in the current round. Once a bet is made, remaining players must fold, call, or raise.
What happens if someone is all-in?
If a player puts their entire stack in and is all-in, they cannot make further betting actions — but they still see the remaining streets dealt out. Side pots are created for chips that remaining active players continue to contest.
Why position matters so much
On every postflop street, the button acts last. They see what everyone else does before deciding — check back, value bet, or bluff with maximum information. Acting last post-flop is the single biggest positional advantage in Texas Hold'em.
The small blind and big blind act first on every postflop street — they are out of position against everyone else. For strategy, see Why Position Matters in Texas Hold'em.
Sample hand: all four streets (heads-up)
In heads-up, the button and small blind are the same player (BTN posts $1, BB posts $2). All pot totals below are $6 + $6 = $12 preflop — each player's total contribution, not blinds plus raise on top.
- Blinds posted: BTN/SB puts in $1, BB puts in $2.
- Hole cards dealt.
- Preflop: BTN (SB) raises to $6 total. BB calls ($4 more to match $6). ($12 in the pot.)
- Flop (e.g., K♠ 7♦ 2♣). BB checks. BTN bets $8. BB calls. ($28 in the pot.)
- Turn (e.g., 9♥). BB checks. BTN bets $18. BB calls. ($64 in the pot.)
- River (e.g., 3♠). BB checks. BTN bets $40. BB folds. BTN wins the $64 pot without showdown.
BB acts first on every postflop street and BTN acts last — standard heads-up order, and a textbook example of why position is power in No-Limit Hold'em.
Common beginner mistakes about action order
- Acting out of turn: Wait until it is your turn. Acting early gives other players free information.
- Forgetting the BB can check preflop: If no one raises, the big blind may check and see the flop.
- Assuming the button acts first postflop: The button acts last postflop, not first.
- Using preflop order after the flop: Find the first active player left of the button — not necessarily UTG.
- String betting: When you raise, put the full amount in one motion or announce "raise" first.
How nlh.poker handles action order
On nlh.poker, action order follows standard No-Limit Texas Hold'em rules:
- 6-max tables use UTG → MP → CO → BTN → SB → BB preflop when six players are seated.
- With fewer players, early positions are removed — for example, UTG does not exist at a 4-handed table.
- Postflop action starts from the first active player left of the button.
- The interface highlights the current actor so you can learn the correct order while playing.

Summary
Texas Hold'em action order is street-dependent. Preflop starts left of the big blind; postflop starts left of the button. The button acts last after the flop, which makes it the strongest position. Learn the order for your table size, watch who is still active after each street, and practice until the sequence feels automatic.
