Definition
Order of action determines who acts first, second, third, etc. in a betting round. This order differs between preflop and postflop, and understanding it is key to using position effectively.
Preflop Order
Action starts left of the big blind and moves clockwise.
9-Handed Preflop Order:
1. UTG (Under the Gun)
2. UTG+1
3. MP (Middle Position)
4. LJ (Lojack)
5. HJ (Hijack)
6. CO (Cutoff)
7. BTN (Button)
8. SB (Small Blind)
9. BB (Big Blind) ← Acts LAST preflop
BB has the "option" — even if no one raised, BB can still raise.
Postflop Order
Action starts with the first remaining player left of the button.
Postflop Order (if all remain):
1. SB (Small Blind) ← First to act
2. BB (Big Blind)
3. UTG
4. UTG+1
5. MP
6. LJ
7. HJ
8. CO
9. BTN (Button) ← LAST to act
The Key Difference
| Street | First to Act | Last to Act |
|---|---|---|
| Preflop | UTG | BB |
| Postflop | SB (or first remaining) | BTN (or last remaining) |
Why Order Matters
🎯 Acting Last = Advantage
When you act last:
- See all opponent actions first
- Have maximum information
- Control pot size more easily
- Bluff more effectively
😰 Acting First = Disadvantage
When you act first:
- No information about opponent hands
- Must guess what they'll do
- Harder to bluff
- Easier to be exploited
Practical Examples
Example 1: Preflop
6-max table. You're on the button with K♠ Q♥.
UTG folds → HJ folds → CO calls $2 → BTN (you) ???
You've seen 3 actions. You know CO is weak (just called). You can raise confidently.
Example 2: Postflop
Flop: A♠ 7♣ 2♦
SB checks → BB checks → CO checks → BTN (you) ???
Everyone checked to you. They're all showing weakness. Great spot to bet!
Heads-Up Order (Special Case)
| Street | Dealer (BTN) | Non-Dealer |
|---|---|---|
| Preflop | Acts FIRST | Acts last (BB) |
| Postflop | Acts LAST | Acts first |
Heads-up preflop is reversed! The button/SB acts first preflop.
Order Summary Table
| Scenario | First to Act |
|---|---|
| Preflop (multi-way) | UTG |
| Preflop (heads-up) | Button/SB |
| Postflop (all streets) | First player left of BTN |
Key Takeaway
Position is the most underrated advantage in poker. Acting last lets you make informed decisions while opponents guess blindly. Always consider order of action when planning your strategy.
