Under the Gun vs Button: Worst vs Best Seat
Under the gun vs the button: why UTG is the worst seat and the button the best, with a side-by-side range and strategy comparison for each position.
On this page · 7 sections
The button is the best seat in poker and under the gun (UTG) is the worst, and the reason is the same for both: who acts after you. On the button, nobody does post-flop, so you always decide with the most information. Under the gun, the entire table acts after you, so you’re forced to commit first and play out of position all hand. They sit at opposite ends of the positional spectrum, and they demand nearly opposite strategies.
Where each seat sits
Under the gun is the seat immediately left of the big blind — first to act pre-flop. The button is the seat on the dealer marker, last to act on the flop, turn, and river. Between them sit every other position, so UTG and the button are effectively the two poles of the table.
The single number that explains the gap is players left to act. Under the gun, everyone but the blinds still gets to respond to your open. On the button, only the two blinds remain — and they’re stuck out of position for the rest of the hand.
The core trade-off
| Factor | Under the gun | Button |
|---|---|---|
| Pre-flop action | First to act | Second-to-last |
| Post-flop position | Out of position | Always in position |
| Players left to act (open) | Many | Two (the blinds) |
| Typical opening range | ~12–15% | ~45% |
| Best mindset | Tight and value-heavy | Wide and aggressive |
The button gets to see what everyone else does before committing chips, which is why it’s poker’s most profitable seat. Under the gun gets no such information, which is why it’s the toughest position to play. The underlying principle — acting last wins — is covered in why position is important.
Range comparison
Because so many players can act behind an UTG open, only hands strong enough to survive that gauntlet get raised. On the button, the near-empty field lets you open far wider for value and blind steals.
| Hand group | Open UTG? | Open button? |
|---|---|---|
| Big pairs (TT+) | Yes | Yes |
| Small/mid pairs (22–99) | Selective | Yes |
| Strong Broadways (AQ, AK, KQs) | Yes | Yes |
| Suited connectors (76s–T9s) | Rarely | Yes |
| Suited aces (A2s–A9s) | A5s type only | Yes |
| Weak offsuit (KTo, QJo, A9o) | No | Yes |
The button opens roughly three times as many combinations. Everything the button adds — the gappers, the weak suited aces, the offsuit Broadways — needs position to be profitable, which is exactly what UTG lacks. Dial in exact frequencies with preflop ranges.
Worked example: same hand, opposite plays
You look down at A♣ 9♣ (A9 suited).
- On the button, it folds to you. Easy raise. Only the blinds are left, you’ll likely take it down pre-flop, and if called you play every street in position. A9s is a comfortable steal here.
- Under the gun, same cards. Now fold. With the whole table behind you, A9s is dominated too often by the stronger aces and Broadways that continue against an early raise, and you’d be out of position on any flop you do see.
Nothing about the hand changed — only the seat. That flip from “raise” to “fold” is the entire lesson of UTG vs the button.
How they get attacked differently
The two seats don’t just open differently — they get played against differently, and understanding that sharpens both.
- UTG gets 3-bet lighter. When you raise under the gun and a late-position player 3-bets, they know you’re capped at a tight range, but they also know you’ll be out of position all hand. Good players will re-raise you with a polarized mix and lean on their position, so your continues need to be strong and mostly played for value or as clean folds.
- The button gets 3-bet by the blinds. Because the button opens so wide, the blinds must fight back or get run over. Expect frequent 3-bets from the big blind especially. The difference is that even after calling a 3-bet, the button is still in position post-flop — a huge cushion UTG never gets.
So the same action, a 3-bet, is a much bigger problem under the gun than on the button. That asymmetry is another face of the same positional gap.
How to play each
Under the gun:
- Open tight — premium pairs, strong aces, and top Broadways only.
- Never limp into the field hoping to see a cheap flop out of position.
- Fold more to 3-bets; you’ll be out of position if you continue.
Button:
- Open wide when it folds to you — punish the blinds relentlessly.
- Use last action to bluff, take free cards, and control pot size.
- Flat more speculative hands; position lets you realize their equity.
The bottom line
Under the gun and the button are the same table’s opposite corners: one plays first and blind, the other plays last and informed. Tighten right up under the gun, open the throttle on the button, and let the seat — not just the cards — set your range every hand. Start from the positions hub to master the seats in between.
Frequently asked
Which is better, under the gun or the button?
The button is far better. On the button you act last on every post-flop street with the most information; under the gun you act first pre-flop and are out of position to nearly everyone, making it the toughest seat at the table.
How much wider is the button range than UTG?
Roughly two to three times wider. A solid UTG open is about 12–15% of hands in a full-ring game, while the button opens around 45% when it folds to you, because far fewer players can act behind.
Why is under the gun called the worst position?
You act first pre-flop with the whole table behind you, and you're out of position on every later street. More players yet to act means a higher chance one of them wakes up with a strong hand.
Should I ever play UTG like the button?
No. Opening a button-wide range from under the gun is a classic leak. The number of players behind you demands a tight, value-heavy range; save the wide, aggressive stuff for late position.
