The Four Streets and Order of Action
The full timeline of a Hold'em hand — preflop, flop, turn, river — plus the two different action orders and the exact conditions that close a betting round.
Assumptions: All examples use a 6-max online cash game at $0.50/$1 with 100 big blind stacks and no rake unless a different setup is stated.
Every Hold'em hand follows the same fixed timeline: cards, betting, more cards, more betting, until either everyone but one player folds or the hand reaches showdown. The timeline never varies. What does change — and what confuses beginners constantly — is who acts first, because preflop and postflop use two different starting points. This lesson nails down the full sequence so you always know what's coming next and whose turn it is.
The four streets
A "street" is a betting round. There are at most four in a hand:
- Preflop. Everyone has two hole cards and nothing else. The blinds are already in the pot. A betting round happens.
- The flop. Three community cards are dealt face up in the middle, all at once. A betting round happens.
- The turn. One more community card, face up. A betting round happens.
- The river. The fifth and final community card. The last betting round happens, followed by showdown if two or more players remain.
The five face-up cards in the middle are the community cards (or "the board"). They belong to everyone equally — your final hand is the best five-card combination you can assemble from your two hole cards plus the five board cards, in any mix. The board never "belongs" to the player who bet at it.
A hand can end on any street. If you bet the flop and everyone folds, there is no turn — the pot is shipped to you and the next hand begins. Roughly speaking, most pots online never see a river; the betting rounds do as much work as the cards do.
The burn card
In a live game, the dealer discards — "burns" — the top card of the deck face down before dealing the flop, again before the turn, and again before the river. Three burn cards total per full hand. The original purpose was security: if the back of the top card was marked or accidentally flashed, burning it kills the information. Online sites burn cards too (or simulate the same thing), purely by convention; a random number generator doesn't need the protection.
Burn cards are dead. They are never shown and never come into play. The only practical reason to know about them is so you don't panic in a live game when the dealer slides cards off the deck without showing them — that's normal procedure, not a misdeal.
Two different action orders
Here is the rule that you must burn into memory, because it governs every hand you'll ever play:
- Preflop, action starts with the first player left of the big blind (the seat called UTG at a full or 6-max table) and moves clockwise. The blinds act last preflop — the SB after the button, the BB last of all. This is fair compensation: they were forced to put money in blind, so they get maximum information before deciding.
- On every postflop street (flop, turn, river), action starts with the first still-active player to the left of the button and moves clockwise. The button — or, if the button has folded, the nearest active seat to its right — acts last.
Notice what this means for the blinds: they enjoy acting last exactly once, preflop, and then pay for it the rest of the hand by acting first on the flop, turn, and river. Conversely the button acts in the middle of the pack preflop but last on every postflop street. The memory hook is two anchors, one seat apart: preflop starts left of the BB; postflop starts left of the BTN.
What closes a betting round
A betting round ends when both of these are true:
- Every active player has had a turn to act, and
- Every active player has put in the same amount for that street (or is all-in for less).
If nobody bets, the round closes when everyone has checked. If someone bets, the round closes once every remaining player has either called the full amount or folded. Any raise re-opens the action: players who already called must now respond to the new amount before the street can end.
One special case lives preflop: the big blind's option. Because the BB already has $1 posted, if everyone just calls $1 (a "limp"), the action reaching the BB isn't facing a raise — the BB may check to close the round or raise to re-open it. The round isn't over until the BB has exercised that option. New players often think a preflop round ends when the bet gets back to the original amount; it ends when the last player with a live decision has made it.
A complete hand, street by street
Watch the whole machine run once. You're in the cutoff with Q♠J♠ at a $0.50/$1 6-max table, 100bb deep.
Trace the order on each street:
- Preflop: the deal ends, and the first voice belongs to UTG — first seat left of the BB. UTG and HJ fold, you raise to $2.50 from the CO, the button and small blind fold, and the big blind calls $1.50 more. Everyone active has now matched $2.50, and the BB (last to act preflop) has made his decision. Round closed. Pot: your $2.50 + BB's $2.50 + the SB's dead $0.50 = $5.50.
- Flop K♠T♠4♥: new street, new starting point. The BB is the first active player left of the button, so he acts first — he checks. You act last and bet $2.75 (half pot). He calls. Both players have matched; round closed. Pot: $11.00.
- Turn 2♦: BB checks first again, you check back. Nobody bet, everyone checked, round closed. Pot unchanged.
- River 9♥: BB checks, you bet $8, he calls, round closed — and because two players remain after the final round, you go to showdown.
About that flop: K♠T♠4♥ gave your Q♠J♠ a monster draw — any spade completes a flush and any ace or nine completes a straight. That's 9 spades plus 3 non-spade aces plus 3 non-spade nines = 15 outs. From the flop, 15 outs come in 32% of the time on the turn and 54% of the time by the river; even against a hand as strong as top pair with K♥J♣, your "draw" was actually a 55% favorite with two cards to come. You'll study draws properly later — the point here is to see how the street structure (two more cards coming on the flop, one more on the turn) is exactly what makes flop draws so much more valuable than turn draws. After the turn bricked, your 15 outs were worth only 33% with one card left.
The 9♥ river made your straight: 9-T-J-Q-K, using both hole cards with the board's K, T, and 9. You bet, got called, and tabled the winner.
The blinds act first postflop — even when they were the aggressor
A second example, because this is the spot where beginners misfire most. Many new players believe "the raiser acts last" or "the caller checks to the raiser by rule." Neither is true. Position is fixed by seat, not by who did the betting.
The small blind raised preflop, the big blind called. Flop comes Q♣8♠3♥ — and the SB must act first, despite having been the raiser, because the SB is the first active seat left of the button. Same on the turn, same on the river if the hand had gotten there. When players say checking is "checking to the raiser," they're describing a common choice, not a rule. The order of action never bends to the betting history.
Flip it around and you see why the button is gold: whoever holds the button sees everyone else's postflop decision before making their own, on all three postflop streets, in every single hand.
When a round does and doesn't close: quick drills
Run these scenarios in your head — each one tests the closing rule.
- Three players see a flop. First player checks, second bets $5, third calls, first folds. Closed? Yes: everyone has acted, and the two remaining players have $5 each in for the street. Deal the turn.
- Heads-up on the turn. First player bets $10, second raises to $30, first calls $20 more. Closed? Yes — the raise re-opened action only for the original bettor, who has now called. Both players have $30 in for the street.
- Preflop, three limpers call $1, SB completes, BB checks... wait, must the BB act at all? Yes — and until the BB checks or raises, the round is open. The BB checking is what closes it. If the BB raises to $5 instead, every limper gets a new decision.
- Flop, first player bets $6, second player raises all-in, first player hasn't responded. Open — a player still faces an unmatched bet. The street can't end until he calls or folds.
The pattern in all four: a street ends only when the last live decision has been made and the money is even (or someone is all-in for less — side pots come in a later lesson).
Heads-up: the one configuration with its own order
When the table is down to two players, the action orders compress but keep their logic. Preflop, the button (who also posts the small blind heads-up) acts first — he's the one facing the larger forced bet. Postflop, the big blind acts first and the button acts last, exactly as the left-of-the-button rule predicts, since the BB is the only seat left of the button. So heads-up the two anchors produce opposite answers on purpose: button first preflop, button last on every later street. If you've internalized "preflop starts left of the BB, postflop starts left of the BTN," heads-up isn't an exception at all — both rules are just being applied to a two-seat circle.
Order is information — guard yours
Why does poker bother with such rigid sequencing? Because acting later means deciding with more information, and the rules are engineered to rotate that advantage fairly. That's also why acting out of turn is treated seriously in live rooms: folding, checking, or betting before the action reaches you hands the players still waiting a free look at your intentions. A player who was going to bluff may now check; a player who was going to value-bet thin may now bet bigger. Online, the software physically prevents it. Live, the discipline is yours: track whose turn it is on every street, act only when the action arrives, and keep your cards and chips still until then. The same logic explains why you should make every action in one clear motion — hesitation, half-reaches, and pulled-back chips all leak the thing this whole structure is designed to ration.
The full timeline at a glance
- Blinds posted → hole cards dealt → preflop betting, starting left of the BB, BB closes with his option.
- Burn → flop (three cards) → betting, starting left of the button.
- Burn → turn (one card) → betting, starting left of the button.
- Burn → river (one card) → final betting, starting left of the button → showdown if two or more players remain.
Five community cards maximum, four betting rounds maximum, three burn cards, two action orders, one button that everything is measured from. Once this sequence is reflexive, you can stop thinking about whether it's your turn and start thinking about what to do with it — which is where the rest of this course lives.
