Tell (poker)

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A tell in poker is a change in a player's behavior or demeanor that is claimed by some to give clues to that player's assessment of their hand. A player gains an advantage if they observe and understand the meaning of another player's tell, particularly if the tell is unconscious and reliable. Sometimes a player may fake a tell, hoping to induce their opponents to make poor judgments in response to the false tell. More often, people try to avoid giving out a tell, by maintaining a poker face regardless of how strong or weak their hand is.


A tell may be common to a class of players or unique to a single player. Some possible tells include leaning forward or back, placing chips with more or less force, fidgeting, doing chip tricks, displaying nervous tics or making any changes in one's breathing, tone of voice, facial expressions, direction of gaze or in one's actions with the cards, chips, cigarettes or drinks.[citation needed]

An underlying rule to many tells is: "weak means strong, strong means weak."[1] Thus, players who hold weak poker hands attempt to convince other players at the table that they are strong: staring down an opponent, throwing chips down forcefully into the pot in an effort to discourage others from calling. Alternatively, players who hold strong hands tend to try to disguise their hand as being weak. They attempt to fly under the radar by being a passive player at the table - not making direct eye contact, softly tossing the chips in, being friendly and talkative. They are deliberately trying not to come across as intimidating, so as to entice a call.

Online tells[edit]

Non-physical tells exist in both casino and online poker, but tells like speed of play,[2] betting patterns,[3] the quantity of chips that a player plays with, and player chat[4] can be particularly revealing online.

Online Poker tools exist to assist players in making these tells more tangible without closely paying attention.

Online Poker Reliable Tells[edit]

Timing tells were proven to be reliable by analyzing large sample sizes at PokerStars $2/$5 Zoom games. Studies on trends such as "RFI Fold to 3bet%" and "3bet Fold to 4bet%" based on timing ranges were shown to have a 9% and 11% edge respectively when properly applying timing tells.[5][6] These studies were also found to be more reliable versus the common regular, rather than the common weaker player.[7]


A player's tell gives information only about that player's assessment of his own cards, and hence is reliable only when that player has accurately assessed his own hand.[citation needed] An unskilled player may misread a weak hand as a strong hand and thus their tells will only indicate this misinterpretation.

Players can also make mistakes that may seem like a tell, like fumbling chips out of clumsiness or betting the wrong amount online when clicking the wrong button.

In popular culture[edit]

David Mamet's 1987 movie House of Games includes as an essential part of the plot a discussion and visual reference to the tell.

The movie Rounders contains an even more subtle use of strategy: at one point, Mike discovers that his opponent changes the way he eats a cookie after betting an especially strong hand, and after using that knowledge once, Mike reveals to the opponent that he has discovered this tell. Mike's tactic works: although his revelation eliminates the usefulness of the tell itself, it upsets his opponent so much that it disrupts his subsequent play (q.v. tilt).

A popular reference to poker tells also appeared in the episode "Casino Night" of the U.S. television-series The Office: Dwight believes that Jim coughs every time he has a strong hand, but Jim really coughs only to make Dwight fold, because Jim knows that Dwight believes that coughing is Jim's tell.

In the M*A*S*H sixth-season episode "The Merchant of Korea," Hawkeye and B.J. lure Winchester, a beginner at poker, into a game with the intention of taking advantage of his inexperience. Winchester instead has an amazing lucky streak, until the other players realize that his incessant whistling (of a passage from Verdi's La traviata) grows louder when he is holding a weak hand and bluffing. Using this knowledge, the other players proceed to win back all of their money, and more.

In the episode "All In" of the television series House, M.D., House analyzes Cuddy's poker gameplay over the phone based on a reports of her tells given to him by Wilson.

In the episode "Contenders" of the television series Numb3rs, Charlie Eppes tries to find an opponent's tell before he plays in a Texas hold 'em game.

One plot turn in the 2006 James Bond film Casino Royale hinges on Bond's belief that terrorist financer Le Chiffre must hide an eye twitch when he bluffs. However, Le Chiffre learns that Bond knows his tell and uses it against Bond to call an all-in bet.
