Two players are dealt K♠ 9♦. The first one folds without much thought. The second one raises. Same hand, opposite decisions — and both might be completely right.
What explains the difference? Position in poker. Where you sit relative to the dealer button determines when you act, and that timing creates an edge that beginners consistently underestimate.
What Is Position?
Position in poker refers to where you sit relative to the dealer button — specifically, whether you act before or after your opponents on each betting round.
Acting after your opponents is called being "in position." Acting before them is called being "out of position." When you're in position, you've already seen what your opponents do — whether they check, bet, raise, or fold — before you have to decide anything. That information is enormously valuable.
When you're out of position, you decide first, without knowing what's coming. You bet, your opponent raises. You check, your opponent bets. On every street, you're reacting to someone who already reacted to you. That recurring disadvantage adds up across every hand you play.
The 6 Positions in 6-Max
FoundationPoker focuses on 6-max cash games — tables with up to 6 players. In a full 6-max game, preflop action moves clockwise starting from the player left of the big blind:
Under the Gun (UTG)
Under the Gun is the first player to act before the flop. With five opponents still to act behind you, you're at the biggest informational disadvantage at the table. Any of them could wake up with a strong hand after you've already committed chips.
UTG demands the tightest, most selective starting hands. You should play hands that are strong enough to be comfortable against a raise from any position — pairs, strong aces, strong suited connectors.
Hijack (HJ)
The hijack is one seat to the left of UTG, second to act preflop. You still have four players behind you, so the range should stay fairly tight — only a little wider than UTG. The name comes from the idea of "hijacking" the late-position advantage from players further around the table.
Cutoff (CO)
The cutoff is one seat to the right of the button, third to act preflop. Three players remain behind you. You can open a noticeably wider range here because fewer players are left to act and the button might fold, letting you pick up position postflop by default.
Button (BTN)
The button is the best seat at the table, full stop. On every postflop street — the flop, turn, and river — you act last. You see every check, every bet, every hesitation before you decide anything.
This consistent last-action advantage means you can profitably play a much wider range of hands from the button than from any other seat. You can call with speculative hands you'd fold elsewhere, bluff more selectively, and control the pot size with information your opponents don't have.
Small Blind (SB)
The small blind posts half a big blind before cards are dealt. Preflop, you act second-to-last. But on every postflop street, you act first — before the big blind, before everyone else. No information before you decide.
Playing out of position for the entire hand is a meaningful disadvantage. Hands that are profitable from the button can lose money from the small blind over a large sample of hands.
Big Blind (BB)
The big blind posts a full big blind before seeing cards. Preflop, you act last among all players and can raise or close the action after seeing everyone else's decision. That's a useful position for exactly one street.
Then the flop arrives and you're out of position for the rest of the hand. Like the small blind, the big blind loses money on average over time — the forced bet combined with postflop position puts you at a structural disadvantage even when you play well.
Why the Button Wins and the Blinds Lose
Consider a hand where the big blind and the button both call a preflop raise and see a flop heads up.
On the flop, the big blind acts first. Whatever they do — check, bet, raise — the button responds with full knowledge. If the big blind checks, the button can bet or check back, controlling the narrative. If the big blind bets, the button can call, raise, or fold with context about what that bet likely means.
On the turn and river, the same thing happens again and again. The button makes every decision last.
Over a long session, this information gap compounds. The button wins pots it has no business winning because it can bluff when its opponent shows weakness. It controls pot size when it wants a small pot and builds the pot when it wants a large one. The blinds, meanwhile, make decisions without that feedback loop — and it costs them.
How Position Affects Which Hands to Play
Back to the K♠ 9♦ example. K-9 offsuit is a hand most experienced players fold from UTG and raise from the button. Why?
From UTG, K-9 offsuit faces five players still to act. Your hand is vulnerable to domination — if someone behind you holds K-J or K-Q, you share a king but they win almost every time one hits the board. You'll also play the entire hand out of position against anyone who calls, which compounds the problem.
From the button, only two players remain (small blind and big blind). They'll often fold. If they call, you'll act last on every postflop street. You can steal pots with a bet on boards that miss everyone, and you can play more confidently when you do connect with the board because you're never guessing what's behind you.
Same cards. Very different situation.
A practical rule for beginners: play fewer hands from UTG and the hijack. Play more from the cutoff and button. Be cautious in the blinds even when pot odds look appealing, because the postflop disadvantage is real and ongoing.
Position Is Fixed for the Entire Hand
One thing that surprises new players: position doesn't reset between streets. Whoever is on the button acts last on the flop, the turn, and the river. Whoever is in the small blind acts first on all three streets. Your position is set when the hand begins and stays the same all the way through.
This is why the button is such a durable advantage. It's not a one-time edge — it's a structural advantage that recurs every time the action comes around.
Practice
Recognizing positions quickly is a learnable skill. The position drill at /basics/positions shows you a table, highlights a seat, and asks you to name the position. Run through it until UTG, HJ, CO, BTN, SB, and BB are automatic.
Then take that knowledge into the preflop trainer at /preflop, which pairs position with actual starting hand decisions. Understanding position on a diagram is one thing — applying it under pressure is another.
The single most actionable thing most beginners can do right now: tighten up from early position and loosen up from the button. No other adjustment produces more improvement with less effort.
