How to use information theory in texas holdem

There are three key elements to understand if you want to become an effective Texas Holdem poker player. First is the general rule of probabilities, which is the first aspect that new poker players study and attempt to master. Some even get good at it, but the difference between good players and great players is the ability to also include the other two elements into your play: Game Theory and Information Theory. In its most basic description, Information Theory is knowing how to notice and analyze the various bits of information that are given during a hand of Texas Holdem poker. If practiced often enough, any player can become quite skilled at using Information Theory to become a better Texas Holdem player. Here’s how its done.

How to Use Information Theory in Texas Holdem

1. First and foremost, understand that everything you see is a piece of information. Every card on the table, every bet, every raise, every movement on your opponent’s face--these are all individual pieces of information. Some bits of information are important and should be used in your game, while others are meaningless and should be ignored. Learning to distinguish between the two is why you practice using Information Theory in a Texas Holdem poker game.

2. Evaluate your hole cards. Each player will be dealt two cards face down at the start of the hand. This is your first piece of information, and it is usually a cheap piece of information. Look at what your cards are. If you have two high cards (higher than 10), two cards of the same suit, or two cards that are close to each other in order (4-6), then your cards are worth playing. If you have anything else, toss it aside and wait for the next hand.

3. Analyze the flop. The flop is the first three community cards that are turned over by the dealer. Combined with the two cards in your hand, you now know 5 of the 7 cards that you will have to work with. This makes the flop one of the most critical pieces of information you will get in your poker game. Consider what cards you will need to catch in order to make your poker hand. If it is more than two, then you obviously don’t stand a chance since there are only two more cards coming.

4. Consider whether or not you should play the Turn or River cards. These are the 4th and 5th community cards that the dealer turns up on the board. If your hand does not look good on the Flop (Step 3), then you should not proceed to this level. The primary thing to keep in mind when evaluating the turn or the river is the information you are picking up about the strength of other players hands. If there is a lot of betting and raising going on, and you do not have anything more than a draw, then Information Theory dictates that you should save your money for another hand where the odds are more in your favor. After all, you want that money going into the pot on a hand that you are likely to win, not lose. This is particularly true when it comes to training yourself to not chase bad information. If you are on a draw and someone is betting, there is no reason to put your money into the pot on nothing more than a prayer of catching a miracle card. You may actually win it on the river sometimes, but over the long run, you will lose money with this style of play.

5. Take mental notes of other player’s playing habits. This can provide you with even more information than watching for physical mannerisms. Does your opponent have a tendency to bluff at the pot or make larger than normal value bets to try to take it down? Have you seen them pick up several pots after slow playing all the way to the river? Taking note of how people play other hands. Whether you are in the hand or not, this provides you with information about how they may be playing other hands. Some people are smart enough to switch up their playing style periodically, but many amateur players remain locked into their comfortable routine, making it easy for you to pick up information about the strength of the cards in their hand.

6. Pay attention to how players bet from different positions. Players who raise or reraise the pot from early positions are sending you information that says they have a strong hand. Someone who just calls from late position is probably just wanting to see the next card as cheaply as possible. This is ideally the best position to be in, because it allows you to evaluate the moves of other players before making a move yourself.

Tips & Warnings

• Do not look at your cards right away. Instead, look at your opponents face as they look at their cards. Their facial expression may inadvertently reveal important information to you. The same goes with cards that the dealer turns up on the board; watch your opponent’s reaction before looking at the board.
• Regardless of how skillful you play the game, there will always be times when luck prevails over skill. If someone playing a poor hand gets lucky and sucks out a victory on the river, do not lose your cool and blow the next hand. Steaming will get you nothing but another loss. Likewise, do not try to target that person specifically as a revenge move. Take your victories where you can find them, regardless of who has put chips in the pot.
