Position is the most valuable asset in poker. Playing "in position" — acting after your opponent — gives you access to information they don't have: you see their actions before making your own decisions. This simple advantage defines which hands are playable, how often to bet, and how to control pot size.
Understanding positions is the first real step on the path of any serious player. Everything else — ranges, preflop strategy, postflop — depends on this.
1. Seats at the Table
At a 6-player table (6-max, the most popular online format), the seats are:
| Position | Abbr. | Acts preflop |
|---|---|---|
| Under the Gun | UTG | 1st (worst) |
| Middle Position | MP | 2nd |
| Hijack | HJ | 3rd |
| Cutoff | CO | 4th |
| Button | BTN | 5th (best) |
| Small Blind | SB | 6th preflop / 1st postflop |
| Big Blind | BB | Last preflop / 2nd postflop |
Seats are divided into three groups based on their positional advantage:
2. Why Does Acting Last Matter?
When you act last postflop you have a massive informational advantage:
- InformationYou see whether your opponent bets, checks, or folds before deciding. A check can signal weakness.
- Pot controlYou can bet to grow the pot with strong hands, or simply check back to get a free card on the next street.
- Efficient bluffingIf the opponent checks, you have the option to bet as a bluff. They've already shown weakness.
Example: A♠ J♥ in different positions
In UTG: 5 players still left to act. Someone may have AK, AQ or a pair. High risk.
On BTN: everyone checked/folded to you. You likely have the strongest hand in the probable range. You can open comfortably.
3. How to Adjust Your Range by Position
The golden rule: the later you act, the more hands you can profitably play.
| Position | % of playable hands | Example openable hands |
|---|---|---|
| UTG | ~8–12% | AA–77, AKs–AJs, AKo–AQo, KQs |
| HJ | ~18–22% | + 66–55, A9s, KJs, QJs |
| CO | ~25–30% | + small pairs, suited connectors |
| BTN | ~40–50% | + almost any decent hand |
Why such a big difference? In UTG there are 5 active players who may have a better hand. On BTN, only the blinds.
4. SB and BB: The Special Positions
The blinds are unique positions because they post forced money but have structural disadvantages.
Small Blind (SB)
Acts last preflop (except vs BB), but always first postflop. It's the hardest position to defend. The pros: folding SB vs a BTN raise is correct many times even if you already have chips invested.
Big Blind (BB)
Acts last preflop (closes the action). You already have 1 BB invested, giving you better pot odds to defend vs raises. However, you're second to act postflop — always out of position vs BTN and CO.
Blind Stealing
When everyone folds to the CO or BTN, raising with a wide range is called a "blind steal." The blinds must defend enough so that constant stealing isn't profitable, but they're at a positional disadvantage forever.
Conclusion
Position isn't just a theoretical concept: it's the filter through which all your decisions pass. Before deciding whether a hand is playable, ask yourself: from what position? The same hand can be an open raise on BTN and a correct fold in UTG.
