Poker tells: clues in how players act

A tell is a change in a player’s behavior that hints at the strength of their hand. Tells can be physical, or about timing and bet size. They are clues, not proof, and work best against a known baseline.

Common live tells

Behavior	Often means	How reliable
Shaking hands on a bet	Strong hand (adrenaline)	Fairly reliable
Staring you down	Often a bluff or nerves	Mixed
Glancing at chips after the flop	Hit the flop, planning a bet	Fairly reliable
Acting bored or looking away	Often strong	Mixed
Talking more than usual	Varies by player	Low

Common views from poker writers; individual players differ.

Where the idea comes from

Poker players have studied tells for as long as the game has been played. Mike Caro’s Book of Tells, first published in 1984, set out many of the ideas still used today, such as weak means strong and strong means weak.

The core idea is that players who hold a strong hand often try to look weak, and those bluffing try to look strong. A player who bets and then leans back and looks away may be more confident than one who stares at you.

Some tells are hard to fake. Adrenaline from a big hand often makes hands shake when chips go in. That is the opposite of what many new players expect, since they read shaking as nerves from a bluff.

Common online and timing tells

Pattern	Often means	Watch out for
Instant check	Weak, giving up	Pre-selected buttons
Instant call	Draw or medium hand	Autopilot play
Long pause then big bet	Often strong, sometimes acting	Players who stall on purpose
Odd bet size	Varies; may be strong	Players who mix sizes

Timing tells online are weaker when players use time banks or auto-actions.

Timing and betting tells

Online you cannot see faces, so timing and bet size carry the signals. A check made within a second or two often means a player has given up. A long tank followed by a raise is often strong, though some players do it on purpose.

Bet sizing tells come from habits. A player who always bets small with draws and large with made hands gives away a lot. Good players use the same sizes with value hands and bluffs, so their sizes say little.

Live players show timing tells too. A quick call on a draw-heavy board can mean a draw. A player who reaches for chips before you act is often trying to stop a bet, which suggests a weak hand.

Hiding your own tells

Most players leak more than they think. A simple routine helps: look at your cards the same way every hand, take the same time for routine actions and put chips in the same way whether strong or weak.

Sunglasses, hats and headphones are common in live poker for this reason. Some rooms limit electronics at the table, so check the posted house rules before you wear headphones or use a phone.

Talking is allowed in most US cardrooms, but you may not give false information that breaks rules, such as stating a hand you do not hold at showdown. Speech play is a skill in itself, and it can backfire.

Tell terms

Know before you sit

Tell: A clue about a hand from behavior.
Baseline: How a player normally acts.
Reverse tell: A fake tell meant to mislead.
Tank: A long pause before acting.

Putting numbers on a read ($100 pot, $50 river bet to call)

Your read	Bluff chance	Call wins	Decision
No read	25%	Break-even	Close call
Weak tell for a bluff	35%	About +$20 per call	Call
Strong tell for value	10%	About -$30 per call	Fold
Tell plus bad price ($150 bet)	35%	About -$10 per call	Fold

You need 25% to call $50 into $150, and 37.5% to call $150 into $250; our own sums assume you only beat bluffs.

Common mistakes

Trusting one tell: Use several clues.
Ignoring baselines: Some players always shake.
Missing reverse tells: Good players fake them.
Leaking your own: Use a routine.
