What is the Button (BTN) in Poker? Why It's the Best Seat
The button (BTN) is the position immediately to the right of the small blind. The player on the button acts LAST on every postflop street (flop, turn, river), which is the single most valuable edge in poker. The button is the most profitable seat at the table — strong players win significantly more from the button than any other position.
Why the button is so valuable
Acting last gives you maximum information before deciding. Three concrete advantages:
- •You see everyone's action first. By the time it's your turn, you know who has bet, who has called, who has folded — that's data your opponents act without.
- •You control pot size. With marginal hands you can check behind to keep the pot small; with strong hands you can bet for value, knowing how much your opponent is willing to put in.
- •You can bluff effectively. When everyone checks to you, a button bet picks up the pot maybe 50-70% of the time even with air. Out of position, the same bluff would be impossible.
How wide to open from the button
Standard 100bb 6-max opening ranges from BTN:
- •Solid range: ~40% of all hands. Includes all pairs, all suited Aces, all suited Kings down to K2s, suited Queens to Q4s, suited Jacks to J6s, suited Tens, all suited connectors, and many offsuit Broadways and connectors.
- •Vs tight blinds: open even wider. If both blinds fold often (>75%), you can profitably steal with 50%+ of hands.
- •Vs aggressive 3-bettors: tighten up. If the BB is 3-betting your opens 14%+ of the time, drop your weakest opens.
Button strategy postflop
On the flop, you'll act last in single-raised pots — a huge advantage. Key principles:
- •Wide c-bets vs single defenders: when only the BB defends, c-bet about 70-80% of flops. You have range advantage on most boards.
- •Float in position: with marginal hands and backdoor draws, calling instead of folding gives you many ways to win on later streets — peeling vs a one-and-done c-bet, taking it away when villain checks turn, etc.
- •Probe turns when checked to: when villain checks the turn after c-betting flop and you called, bet 60-70% pot a high frequency. They've given up.
Button mistakes to avoid
Three common leaks even at micros:
- •Not opening wide enough: many micro players open 25-30% from BTN. You're leaving money on the table — late position justifies far wider opens.
- •Limping behind on BTN: if everyone folds to you on the button, you should NEVER limp. Raise or fold. Limping into blinds gives them odds to defend wider and removes your initiative.
- •Slow-playing strong hands: the button is where you have maximum information, so slow-playing rarely makes sense. Bet for value instead and let villain bluff their weaker hands.

Frequently asked
What does BTN stand for in poker?
BTN stands for 'Button' — referring to the dealer button, a small disc that rotates around the table indicating which player is in the dealer position. The player on the button acts last in every postflop round, which is the most valuable position.
Where is the button in a 6-max game?
Going clockwise from the small blind: SB, BB, UTG, MP (or HJ), CO, BTN. The button is the last seat to act preflop (excluding blinds) and the last seat to act on every postflop street. The button rotates one seat clockwise after each hand.
Why is the button called the 'cutoff plus one'?
The cutoff (CO) is the seat immediately to the right of the button. The button is sometimes called 'CO+1' or 'one off the button' is the cutoff. The button is the most profitable seat; the cutoff is the second-most profitable. Together they make up 'late position.'
Does the button play bigger pots than other positions?
Yes. The button plays the most hands (widest opening range) AND wins the most money per hand played. In a 6-max game, the button typically generates 30-50% of a winning player's total profit despite being only 1/6 of the seats.
What's the 'button is the boss' principle?
The principle that the button has so much positional advantage that they can profitably play more hands and apply more pressure than any other seat. 'BTN is the boss' is a common phrase among poker players to remember the button gets to dictate flow of the hand most often.
