Poker tells: what actually gives a hand away
Updated November 2026
A tell is a habit that leaks information about a player's hand. Faces turn out to give away very little. In a 2013 study, people who watched only professional players' arms judged hand strength better than people who watched their faces.
So here's what the research found, which habits are worth watching, and why the way someone bets beats anything you'll see in their eyes.
Worth watching
- Bet size that changes with hand strength
- Timing that breaks from their usual pace
- How smoothly chips go in
- Who raises, who only calls
Weak signals
- Shaking hands
- Talking more or less than usual
- Looking at chips after the flop
Mostly noise
- Facial expressions
- Staring you down
- Sighing and shrugging
The grouping is our judgment. A habit only counts once you've seen it from this player more than once.
What does the research say?
In 2013, researchers showed 78 students two-second clips of professional players at the World Series of Poker. Some saw only the faces, some only the arms pushing chips in, and some the whole upper body.
People who judged from faces did worse than guessing. People who saw the whole upper body did about as well as chance. People who saw only arms did best, and they tended to read smooth movements as confidence.
The study is in Psychological Science. Those were clips of bets, and the viewers weren't poker players, so treat it as a clue and don't take it as a rule.
Who read the hand best
Why are faces so unreliable?
Because people control them, and good players practice. Everyone knows you're looking at their face, so it's the first thing they learn to manage. Arms get less attention, since the player's mind is on the decision.
Where a player's attention goes
What do betting patterns tell you?
Far more. Every bet is information the player can't take back, it works the same online and live, and you can see it every hand.
- Bet size that changes with strengthMany players bet big with big hands and small with draws. Once you've seen it, every bet reads like a label.
- Raising only with the goodsA player who never raises without a monster has told you what a raise means.
- Limp, then raiseIn a lot of games, this means a very big hand.
- Sudden big river bet from a passive playerThis usually isn't a bluff. Those players don't have one.
- Always checking the same wayA player who checks strong hands one way and weak ones another is easy to read.
- Never showing a bluffIf you've seen 200 hands and no bluffs, believe the next big bet.
Does the speed of a decision matter?
Sometimes. A quick call often means a medium hand that wasn't worth thinking about: strong hands tend to consider a raise, and weak hands tend to consider folding.
A long pause followed by a big bet can be either a real decision or someone acting. So compare it with that player's usual pace, and don't read it on its own.
Typical readings of timing
Which physical tells are worth noticing?
- How chips go inSmooth and deliberate tends to go with confidence, which is what the arm study pointed to.
- Hands shakingOften a sign of excitement from a big hand, and just as often someone with a lot of money at risk.
- Looking away after the flopSome players look away from a flop that hit them. It's unreliable, and fun to watch for.
Why do players act strong when they're weak?
Because most people try to fool you. Mike Caro's book on tells boiled it down to a line players still use: weak means strong, and strong means weak.
A player who sighs and shrugs before betting is usually pretending. A player who slams chips in with a hard stare often wants you to fold. Ask what he's trying to make you do, then do the opposite.
Act and meaning
What is a false tell?
A habit put on purpose to fool you. Good players know what people look for, so they'll shake their hand or grab chips early when it suits them.
That's a reason to give physical tells very little weight against a strong regular. Against someone in their first game, they count for more.
How much weight
How do you keep track of players?
- How many hands do they play?Count how often they put money in before the flop for a full round or two.
- Do they raise or just call?A player who calls a lot and rarely raises is telling you how to play.
- What did they show down?The hand they called with tells you more than anything else you'll see.
- What do they do when they're losing?Some players get wilder after a big loss. Watch for it.
What do online players look at?
Numbers. Two are enough to start with: how often a player puts money in voluntarily before the flop, and how often that player raises before the flop. If the first is 40% and the second is 8%, you're looking at someone who calls too much.
Software that shows these during play is banned or restricted on some sites, so check the rules of the site you're on. You can count the same things by hand at a live table.
Before the flop
How do you hide your own tells?
- Use the same motionPut your chips in the same way every time.
- Take the same timePause for the same few seconds on every decision, big or small.
- Keep the same talkIf you chat, keep chatting. Sudden silence says a lot.
- Bet the same sizesUsing the same bet with strong hands and bluffs takes away the biggest tell of all.
How much should a tell change your decision?
A little. Start with the math: what the price is, what he could have, and how the hand has gone. A tell can tip a close decision one way, and that's about all it should do.
Calling a huge bet with a bad price because someone looked nervous is how tells cost people money.
In order
- The price of the call
- His likely range
- The way he has bet
- Then, if it's close, a tell
Can you tell what's real?
Twelve spots in three rounds.
Questions players ask about tells
What is the most reliable poker tell?
Betting patterns. They're the only tell every player gives on every hand.
Do online players have tells?
Yes: bet sizes and timing. A player who always bets the same size with the same kind of hand is an open book.
Are sunglasses worth it?
Probably not for most people. Going by the research, your face isn't what gives you away.
Do professional players have tells?
Fewer, and they work hard to avoid them. The study above used professionals, which is what makes the result interesting.
Is it rude to stare at other players?
It's normal to watch, and you'll learn more by watching their hands than their faces.
What's the most common tell among beginners?
Betting big with strong hands and small with weak ones. It's easy to spot and easy to fix.
Where this comes from
The study is Slepian, Young, Rutchick and Ambady, "Quality of Professional Players' Poker Hands Is Perceived Accurately From Arm Motions", Psychological Science, 2013. The grouping of tells on this page is our own judgment from how the game is played. Nothing on this page has been measured on real opponents.
