How to Take Useful Notes on Live Poker Players

You recognize the guy two seats to your left.

You’ve definitely played with him before. You remember that he did something unusual preflop. Maybe he raised bigger when he was strong. Maybe he limped a lot but suddenly opened to $20 with premium hands. Maybe he fired the flop constantly and shut down on the turn.

You know there was something worth remembering.

You just can’t remember what it was.

That is one of the frustrating realities of live poker. Over hundreds of hours at the table, you collect valuable information about the people you play against. But unless you record it, most of that information eventually disappears.

Useful live poker notes aren't a record of everything an opponent does. They're a record of the things that can help you make better decisions against that player the next time you meet.

Don't Record Hands. Record Tendencies.

A common mistake is writing notes that look like miniature hand histories:

Called $15 from cutoff. Flop was K-8-4. Called $25. Turn was a 6. Checked. River was a 2. Called $60 with KJ.

There may be useful information buried in that hand, but six months from now you'll have to reconstruct the entire situation to figure out what it means.

A better note extracts the tendency:

Calls raises wide in position. Will call multiple streets with top pair / mediocre kicker.

That tells you something you can use.

A good poker note answers two questions:

What does this player tend to do?

And:

How should I adjust because of it?

The individual hand is evidence. The tendency is what matters.

Start With Preflop Tendencies

Preflop behavior is often the easiest information to collect because you'll see it repeatedly, even when you're not involved in the hand.

Pay attention to how a player enters pots.

Does he:

• Open limp frequently?
• Overlimp behind other limpers?
• Open raise too many hands?
• Open raise only strong hands?
• Call raises too wide?
• Rarely 3-bet?
• 3-bet aggressively?
• Call 3-bets too often?
• Fold excessively to 3-bets?

You don't need precise percentages to make these observations valuable.

You may not know that someone has an exact VPIP of 42%. But after several orbits you may be very confident that he is entering far more pots than a typical solid player.

That's useful information.

Your note might simply say:

Very loose preflop. Limp/calls frequently. Calls raises with weak suited hands and offsuit broadways.

Now you have something actionable.

Against that player, you may value bet more aggressively, isolate his limps with a wider value range, and bluff less when he demonstrates that he doesn't like folding.

Pay Attention to Preflop Sizing

Bet sizing can be one of the most valuable tendencies to record in live poker.

Some players unknowingly change their raise size based on hand strength.

For example, imagine a player normally opens to $10 or $12 but you've now seen him raise to $25 three times.

All three times he showed down a premium hand.

That doesn't mean a $25 raise always means a monster. Three observations aren't enough to turn a tendency into a law.

But it's worth recording.

A useful note might be:

Normal open $10–$12. Has used $25+ with QQ+ twice. Watch for large preflop sizing = strength.

Notice the wording.

You aren't writing:

$25 = aces.

You're recording the evidence and reminding yourself what to watch for.

That distinction matters.

Record Postflop Patterns, Not Just Results

Postflop tendencies are often even more valuable because this is where pots become larger.

Consider continuation betting.

One player may c-bet almost every flop after raising preflop.

Another may c-bet only when he connects with the board.

A third may fire the flop constantly but shut down on the turn unless he has a strong hand.

Those are three very different opponents.

Useful notes might look like:

C-bets very frequently, including bad boards.

Or:

Low c-bet frequency. Flop bet appears value-heavy.

Or:

One-and-done bettor. C-bets flop wide, gives up turn without strength.

The third note is particularly actionable.

If you've repeatedly seen someone bet the flop and then check the turn when weak, his turn check gives you information. You may be able to attack those checks much more aggressively than you would against an unknown player.

That's the point of taking notes.

You're not collecting trivia about your opponents.

You're collecting future decisions.

Separate Observations From Conclusions

One dangerous habit is becoming too confident too quickly.

Suppose a player makes a huge river bet and shows the nuts.

You write:

Huge river bet = nuts.

That's not a tendency.

That's one hand.

A better note would be:

Overbet river with nuts. Watch whether large river sizing is value-heavy.

Now suppose three weeks later you see him make another oversized river bet and show another extremely strong hand.

Update the note:

2 observed river overbets, both very strong value. Large river sizing appears heavily value-weighted.

The more evidence you collect, the more confidence you can place in the read.

Think of your notes as a living profile rather than permanent declarations.

Record Showdowns

Showdowns are particularly valuable because they reveal information that usually remains hidden.

When you see someone's cards, ask yourself what the hand tells you about the way that player thinks.

Did he:

Call a raise with a surprisingly weak hand?

Call three streets with second pair?

Check back a hand most players would value bet?

Bluff the river after missing a draw?

Limp a premium pair?

Call a 3-bet with a hand you didn't expect?

Don't merely record the cards.

Record what the cards revealed about the player's range or decision-making.

Instead of:

Called with 76s.

Consider:

Called MP raise from BB with 76s. Defends BB fairly wide.

Instead of:

Had KK.

Consider:

Limped UTG with KK. Capable of limping premiums.

The second version is far more valuable the next time you play together.

Don't Forget What a Player Doesn't Do

Absence can also be a tendency.

Perhaps you've played ten hours with someone and never seen him 3-bet.

That is worth noting.

Perhaps another player has shown down several strong hands but you've never seen him bluff a river.

Worth noting.

Maybe someone has faced four continuation bets and folded all four times.

Worth noting.

You should be cautious about small samples, but poker exploitation frequently begins by noticing behaviors that occur too frequently—or not frequently enough.

Keep Notes Short Enough to Use

A poker note isn't useful if you need three minutes to read it while sitting at the table.

The best notes are concise.

Compare:

This player seems like he probably calls too often before the flop based on several hands where I saw him call raises and then he had fairly weak holdings at showdown.

With:

Calls preflop raises very wide.

Same information. Much easier to use.

Abbreviations can help too, particularly for tendencies you record frequently:

L/C wide RFI tight Fv3! high CB flop high Turn barrel low River bets value-heavy

The exact shorthand doesn't matter as long as you understand it.

The Most Important Note: What Are You Going to Do About It?

Observing a tendency is only half the job.

Suppose your notes say:

Calls flop and turn extremely wide.

Good observation.

But what is your strategy?

Perhaps:

Value bet thinner. Reduce multi-street bluffs.

Now the note becomes immediately useful.

Another player:

Opens too many hands from late position.

Strategy:

3-bet wider for value. Look for profitable light 3-bets if he folds too much.

Another:

C-bets flop frequently but gives up turn.

Strategy:

Float more favorable flops in position and attack turn checks.

Whenever possible, your player notes should eventually lead to an adjustment.

Observation: what does this player do?

Evidence: what have I actually seen?

Strategy: how can I exploit it?

That is the difference between collecting poker information and actually using it.

Build the Profile Over Time

The greatest advantage of keeping live poker notes isn't necessarily what happens tonight.

It's what happens three months from now.

You walk into the poker room, sit down, and recognize someone you've played with before.

Instead of starting from zero, you already know:

He limps too much.

His unusually large preflop raises have been strong.

He c-bets frequently.

He gives up on turns.

He calls rivers too wide.

And your strategy is already written down.

Live poker players spend hundreds or thousands of hours gathering information about their opponents. Most of it is forgotten.

The goal of taking useful notes is simple:

Keep the information that helps you make money the next time you meet.
