Being able to read your opponent is crucial in poker. It is what differentiates a game of skill such as poker from other games of chance such as roulette. Everybody has poker tells at the table and the more you observe, the better you will be able to read what a player is thinking and what cards they hold. Poker tells include any source of information that you can gather from an opponent including physical movement, changing and patterns of talking as well as how they move the chips around the table.

Eyes The eyes are the windows to a person's soul. The length of stare at hole cards is a key timing tell, each person is different but some people can help but stare longer at their hole cards when they have a big hand. Others quickly snap the cards back down as soon as they see a monster. Another glaringly obvious tell is the glancing to the left consider a steal if in position. Quickly glancing at their chips when the flop comes down usually means they hit a piece of the flop. If a player glances at their chips when they hit it hard, then they will often stare at the flop when they miss.

The Hole Cards Double checking the hole cards usually means a weak hand. People don't often double check big pairs because they remember what it was the first time. Looking away and uninterested after seeing the hole cards is a dead give away for strength. Squeezing out the second hole card sometimes means the first card seen is an ace. Checking the hole cards on a flop that is all the same suited usually implies someone doesn't have the flush.

Patterns of Betting The classic saying in poker is that weak means strong and strong means weak. Looking aggressive and forcefully shipping chips into the middle is usually weak. The opposite is also true, quietly putting chips into the pot is often strength. If an opponent looks at his hand and then bets instantly, it is seldom a bluff.

Chip Stacks Studying how the chips are put out, the amount of bet, whether it is large chips or small chips can give clues to betting tells. Loose aggressive players usually have unorganised stacks while tight conservative players keep neat stacks. Some players keep two stacks in cash games, these type of players will stack their winnings off to the side or in front so they can easily tell how much they are up on the game. If you can determine this, they will be less likely to call a bet which would put them in the red for the game, unless they have a very strong hand. If you ever notice a player winning a large pot, and perhaps may still be stacking their chips from it, they will not play the hand unless they have good cards.

Speaking at the table If an opponent is having a conversation during a poker hand and his talk is all of the place, as if his mind is on something else, it usually means he is not too confident in his hand. This correlates to a weak poker hand. Conversely, if a player is talking smoothly while in a hand, it means he is not overly concerned about the hand he is playing. This is because he feels comfortable and usually means a big hand.

There are many poker tells. If you keep your eyes open and always watch the table, you'll be on the right track to becoming a great player.
