A poker tell is a signal, gesture, or verbal statement that can give away clues on what a poker player potentially has in hand. The sign can come from the slightest body language, the player's eyes and other actions that help evaluate the strength in the cards they have.
Poker tells help opponents plan their next move, although they are also deceiving in some instances. Seasoned players have mastered the art of intentionally displaying actions and expressions to mislead their opponents on the strength of their hands. After playing poker for a while and gaining significant experience, many players can see through the deceit and not fall for the play the opponent puts down.
Here are the most common poker tells:
Playing Too Fast or Too Slow
In general, when a player plays their turn quickly, often, it is a sign of weakness because it shows the player does not have many options. Players who take time before they play give an impression that they hold strong cards, which, if they plan their move carefully, can influence the game's outcome in their favor. Timing is an excellent poker tell, but many players know this is what their opponent is looking at and may intentionally increase or decrease their play rate to confuse their opponents.
The best poker players never miss anything that goes on at the table. For this reason, most players are attentive and have all their focus on the game. When a player seems distracted by external factors, this could be a tell-tale sign that they don't have strong cards and anything else is more important than what they hold. When a player has their eyes on the game, they watch every move to strategize their next play. Attentiveness is not the most substantial poker tell, but it gives a lot of insight.
