Why position matters
Poker is a game of incomplete information. Acting later in a betting round lets you observe more opponents before making your own choice. That informational advantage is why position affects which starting hands can be played profitably in skilled strategy.
Key seats
| Button (BTN) | Dealer position; acts last after the flop in a standard Hold'em hand. |
|---|
| Small blind (SB) | Posts the small blind and usually acts first after the flop. |
|---|
| Big blind (BB) | Posts the big blind; closes preflop action if no further raise occurs. |
|---|
| Under the gun (UTG) | First player to act preflop in a full-ring setup; generally an early position. |
|---|
| Cutoff (CO) | Seat immediately right of the button; a valuable late position. |
|---|
Beginner takeaway
Do not memorize dozens of charts before understanding the principle: the earlier you act, the less information you have. That generally calls for a more selective range.
How position changes a hand
Preflop and postflop are different
Before the flop, the blinds act after the other players, while the button has the strongest informational position after the flop. That is why a hand can be acceptable to open from the cutoff yet too loose from under the gun. Position changes both the number of players left to act and how often you will have to make later decisions without seeing what opponents do first.
Position affects more than starting hands
Late position can make value betting, bluffing and pot control easier because you have observed more actions. Out of position, the same hand may require more cautious lines because your opponent can react after seeing what you do. Strong players therefore think about a hand and its seat together rather than asking whether a starting hand is simply “good” or “bad.”
A practical live-game habit
At a live Toronto-area table, identify the dealer button before looking at your cards. Then count how many players remain behind you. That simple routine prevents many early-position mistakes and makes preflop charts easier to understand rather than memorize mechanically.
