KEY TAKEAWAYS
A poker hand history is a written record of one hand, listing who sat where, what each player did on each street, which cards came, and who won how much. Most of it is simple bookkeeping. To read one, start with the setup (seats, stacks, blinds), follow the actions in order from the hole cards to the river, and finish with the result.
The sample hand below uses 1/2 blinds and 200-chip stacks, and it is entirely hypothetical. Its pot grows from 3 chips after the blinds to 19 after preflop, 35 after the flop and 75 after the turn, before a river bet is made and not called. Once those figures can be rebuilt from the lines, the record can be checked for errors and used for the math of the hand.
This guide shows what every kind of line means, how to rebuild pot and stack sizes, how to turn the lines into pot odds and outs, and which mistakes make a record misleading. It describes the structure that most formats share, not the exact layout of any one room.
What a Poker Hand History Contains
A hand history is a log of the actions in a single hand. Online rooms generate such logs automatically for every hand a player is dealt in. In live games, a player writes the key facts down by hand or in an app, usually after the hand, so the record depends on memory and tends to be shorter.
Every hand history, whatever its layout, answers the same questions. Who was in the hand, and in which position? How many chips did each have? What did each player do, in what order? Which cards were dealt to the player writing it, and which appeared on the board? Who won, and how much?
Two terms help when reading. A street is one betting round: preflop, flop, turn, river. A position is a seat relative to the dealer button: the button itself, the small blind and big blind to its left, then the seats that act first preflop. Hand histories name positions, or give seat numbers, because the order of action follows from them.
Reading a Hand History Line by Line
The sample below is a hypothetical hand in a typical text layout. Most online rooms use something close to this order, but wording, symbols and extra lines differ, so treat it as an illustration and not as any room’s official format.
Hand #1001 | Hold'em No Limit | Blinds 1/2 | 6-max | no rake Seat 1: UTG (200) Seat 2: HJ (200) Seat 3: CO (200) Seat 4: BTN (200) [Hero] Seat 5: SB (200) Seat 6: BB (200) SB posts 1 BB posts 2 *** HOLE CARDS *** Dealt to Hero [A♠ Q♠] UTG folds HJ folds CO raises to 6 Hero calls 6 SB folds BB calls 4 *** FLOP *** [K♠ 9♠ 4♦] BB checks CO bets 8 Hero calls 8 BB folds *** TURN *** [K♠ 9♠ 4♦] [2♣] CO bets 20 Hero calls 20 *** RIVER *** [K♠ 9♠ 4♦ 2♣] [7♥] CO bets 50 Hero folds Uncalled bet (50) returned to CO CO collected 75
The header and the seats
The first line gives the game, the blinds and the table size: no-limit Hold’em, blinds of 1 and 2, six players. The seat lines show each position and its chip stack at the start of the hand. In the sample, everyone starts with 200 chips, and the player writing the record is marked as Hero.
Blinds, hole cards and actions
The posting lines show the forced bets: the small blind puts in 1 and the big blind 2. Under HOLE CARDS comes the only private information the record contains, the writer’s own cards, A♠ Q♠. Every later line is an action in turn order: folds, checks, calls, bets and raises.
One detail trips up new readers: “raises to 6” means a total of 6, not 6 more. The big blind’s “calls 4” means 4 additional chips, because 2 were already posted. Each street header lists the board cards that arrived, and the turn and river headers repeat the earlier cards plus the new one.
The ending
The final lines settle the pot. Because Hero folded to the river bet, nobody called it, so the uncalled bet of 50 goes back to the bettor and only the 75 chips contributed earlier are collected. A hand that reaches showdown would also show the cards each remaining player turned over.
Rebuilding the Pot and the Stacks
The most useful skill in reading a hand history is rebuilding the pot after every action. It confirms the record is complete, and it supplies the pot sizes that every later calculation needs. Start with the blinds and add each bet or call, counting only the extra chips each player puts in.
| Street | Action | Chips added | Pot after |
|---|---|---|---|
| Blinds | SB posts 1, BB posts 2 | 3 | 3 |
| Preflop | CO raises to 6 | 6 | 9 |
| Preflop | Hero calls 6 | 6 | 15 |
| Preflop | BB calls 4 (2 already posted) | 4 | 19 |
| Flop | CO bets 8 | 8 | 27 |
| Flop | Hero calls 8 | 8 | 35 |
| Turn | CO bets 20 | 20 | 55 |
| Turn | Hero calls 20 | 20 | 75 |
| River | CO bets 50, uncalled and returned | 0 | 75 |
The final pot of 75 is what the cutoff collects. Stack sizes follow from the same totals. The cutoff put in 6 + 8 + 20 = 34 chips and won 75, finishing with 200 − 34 + 75 = 241. Hero put in the same 34 and finishes with 166. The big blind put in 6 and finishes with 194, and the small blind put in 1 and finishes with 199.
A useful final check is that chips are conserved. The six stacks end at 200, 200, 241, 166, 194 and 199, which add up to 1,200, the same as the 6 × 200 chips at the start. If the totals do not match, a line is missing, a bet was miscounted, or an uncalled bet was not returned.
Turning the Lines Into Numbers
With pot sizes rebuilt, the record supports the same math as any worked example. Hero holds A♠ Q♠ on a flop of K♠ 9♠ 4♦, which is a draw to the ace-high flush with 9 spades left among the unseen cards. Each bet gives a price, using the formula from how to calculate pot odds: the call divided by the pot after the bet plus the call.
| Street | Call | Pot after the bet | Equity needed | Flush draw chance (9 outs) |
|---|---|---|---|---|
| Flop | 8 | 27 | 8 ÷ 35 = 22.9% | 19.1% next card; 35.0% by the river |
| Turn | 20 | 55 | 20 ÷ 75 = 26.7% | 9 ÷ 46 = 19.6% on the river |
The chances come from counting outs and dividing by the unseen cards: 47 on the flop and 46 on the turn, from Hero’s point of view. The flush chances here count only the 9 spade outs; the ace and queen could also improve Hero’s hand, but their value depends on the opponent’s unknown cards, so they are left out of this simple figure.
The record also gives bet size as a share of the pot. The flop bet of 8 into 19 is 42.1% of the pot, the turn bet of 20 into 35 is 57.1%, and the river bet of 50 into 75 is 66.7%. Tracking these ratios across streets is one of the main reasons to read a hand history closely, because they show how the price of each call changed.
Common Hand History Reading Mistakes
The first common mistake is confusing “raises to” with “raises by”. Treating CO’s raise to 6 as a raise of 6 on top of the big blind inflates the pot by 2 chips, and every pot odds figure after it will be off.
The second is ignoring chips already posted. The big blind’s “calls 4” is only 4 additional chips. Counting 6 would put the preflop pot at 21 instead of 19. A third is forgetting the uncalled bet: without the return of 50 chips, the pot appears to be 125, which does not match the 75 chips the players actually contributed.
A fourth is reading a result as a verdict. In this hand the flush never arrived, but a draw with a 35.0% chance by the river misses 65.0% of the time. One record describes one outcome, and variance means a single hand says little about the numbers behind it. A fifth is copying a hand history with missing lines or guessed bet sizes: every number computed from it will inherit the error.
Using Hand Histories in Practice
Hand histories are useful because they make a hand checkable instead of remembered. Players share them to ask questions, and anyone reading one can rebuild the pot, recompute the pot odds and verify the claims, as done above. The same habit makes calculator and chart output easier to interpret, because the inputs are explicit.
For live games, a short written record is enough if it captures stakes, positions, stack sizes, each action with its size, the board and the result. Conventions vary widely: some players use abbreviations for positions and bet sizes, some tools use their own text formats, and a room’s saved files may use extra lines or different wording. Whether a given file can be shared, and whether a room allows saving hands, depends on the rules of that room and the laws where it operates.
Real-money poker involves real financial risk, and the legal age and legality of playing vary by state and venue. A hand history is a study aid, not a promise of better results.
From Reading a Hand to Analyzing It
Reading a record is the first half of analyzing a hand. The second half is the numbers inside it. Each draw in a record can be turned into a probability by counting outs, and each bet into a price by working through how to calculate pot odds. Together they explain what the lines show: what each decision cost, and how often the hand improves.
A good next step is to take any hand history, rebuild the pot after every action, and compute the price of each call. Doing it once by hand makes every later record faster to read and every later calculation easier to trust.
