Poker is a popular card game that combines elements of chance and strategy. There are various styles of poker, all of which share an objective of presenting the least probable or highest-scoring hand. A poker hand is usually a configuration of five cards depending on the variant, either held entirely by a player or drawn partly from a number of shared, community cards. Players bet on their hands in a number of rounds as cards are drawn, employing various mathematical and intuitive strategies in an attempt to better opponents.
(Redirected from Holdem strategy)
A few card rooms offer spread limit Hold'em. Spread limit Hold'em is stated as 2/10 or something similar. The blinds are the same as fixed limit: For example, in the 2/10 games, the small blind is $1, and the big blind is $2. The difference is that all other bets in spread limit may be anywhere from $2 to $10. Hands like 2-2, 5-5 or 7-7 lose most of their value after the flop unless you make a set (three of a kind) so it’s better not to hold out for something down the river and just cut your losses. You don’t always have to fold on a small pocket as they could lead to a winning hand, but don’t let yourself get carried away just because you start with a pair.
Given the game's many different forms and various dynamics, poker strategy becomes a complex subject. This article attempts to introduce only the basic strategy concepts.
The fundamental theorem of poker[edit]
David Sklansky at the World Series of Poker
The fundamental theorem of poker, introduced by David Sklansky, states: Every time you play your hand the way you would if you could see your opponents' cards, you gain, and every time your opponents play their cards differently from the way they would play them if they could see your cards, you gain.[1] This theorem is the foundation for many poker strategy topics. For example, bluffing and slow-playing (explained below) are examples of using deception to induce your opponents to play differently from how they would if they could see your cards. There are some exceptions to the fundamental theorem in certain multi-way pot situations, as described in Morton's theorem.
Pot odds, implied odds and poker probabilities[edit]
The relationship between pot odds and odds of winning is one of the most important concepts in poker strategy. Pot odds are the ratio of the size of the pot to the size of the bet required to stay in the pot.[1] For example, if a player must call $10 for a chance to win a $40 pot (not including their $10 call), their pot odds are 4-to-1. To have a positive expectation, a player's odds of winning must be better than their pot odds. If the player's odds of winning are also 4-to-1 (20% chance of winning), their expected return is to break even (on average, losing four times and winning once for every five times they play such a pot).
Implied odds is a more complicated concept, though related to pot odds. The implied odds on a hand are based not on the money currently in the pot, but on the expected size of the pot at the end of the hand. When facing an even money situation (like the one described in the previous paragraph) and holding a strong drawing hand (say a Four flush) a skilled player will consider calling a bet or even opening based on their implied odds. This is particularly true in multi-way pots, where it is likely that one or more opponents will call all the way to showdown.
Deception[edit]
By employing deception, a poker player hopes to induce their opponent(s) to act differently from how they would if they could see their cards. David Sklansky has argued that winning at poker is often decided by how much one player can force another to change his/her style while successfully maintaining their own strategy.[2]Bluffing is a form of deception where players bet strongly on a weak hand to induce opponents to fold superior hands. Related is the semi-bluff, in which a player who does not have a strong hand, but has a chance to improve it to a strong hand in later rounds, bets strongly on the hand in the hopes of inducing other players with weaker 'made' hands to fold. Slow-playing is deceptive play in poker that is roughly the opposite of bluffing: checking or betting weakly with a strong holding, attempting to induce other players with weaker hands to call or raise the bet instead of folding, to increase the payout.
Position[edit]
A standard Texas hold 'em game with blinds
Position refers to the order in which players are seated around the table and the strategic consequences of this. Generally, players in earlier position (who have to act first) need stronger hands to bet/raise or call than players in later position. For example, if there are five opponents yet to act behind a player, there is a greater chance one of the yet to act opponents will have a better hand than if there were only one opponent yet to act. Being in late position is an advantage because a player gets to see how their opponents in earlier position act (which provides the player more information about their hands than they have about his). This information, coupled with a low bet to a late player, may allow the player to 'limp in' with a weaker hand when they would have folded the same hand if they'd had to act earlier. Position is one of the most vital elements to understand in order to be a long-term winning player. As a player's position improves, so too does the range of cards with which they can profitably enter a hand. Conversely this commonly held knowledge can be used to an intelligent poker player's advantage. If playing against observant opponents, then a raise with any two cards can 'steal the blinds,' if executed against passive players at the right time.
Reasons to raise[edit]
Unlike calling, raising has an extra way to win: opponents may fold. An opening bet may be considered a raise from a strategy perspective. David Sklansky gives seven reasons for raising, summarized below.[1]
Reasons to call[edit]
There are several reasons for calling a bet or raise, summarized below.
Gap concept[edit]
The gap concept states that a player needs a better hand to play against someone who has already opened (or raised) the betting than he would need to open himself.[4] The gap concept reflects that players prefer to avoid confrontations with other players who have already indicated strength, and that calling only has one way to win (by having the best hand), whereas opening may also win immediately if your opponent(s) fold.
Sandwich effect[edit]
Related to the gap effect, the sandwich effect states that a player needs a stronger hand to stay in a pot when there are opponents yet to act behind him.[3] Because the player does not know how many opponents will be involved in the pot or whether he will have to call a re-raise, he does not know what his effective pot odds actually are. Therefore, a stronger hand is desired as compensation for this uncertainty. A squeeze play exploits this principle.
Loose/tight play[edit]
Loose players play relatively more hands and tend to continue with weaker hands; hence they do not often fold. Tight players play relatively fewer hands and tend not to continue with weaker hands; hence they often fold. The following concepts are applicable in loose games (and their inverse in tight games):[1]
Aggressive/passive play[edit]
Aggressive play refers to betting and raising. Passive play refers to checking and calling. Unless passive play is being used deceptively as mentioned above, aggressive play is generally considered stronger than passive play because of the bluff value of bets and raises and because it offers more opportunities for your opponents to make mistakes.[1]
Hand reading, tells and leveling[edit]
Hand reading is the process of making educated guesses about the possible cards an opponent may hold, based on the sequence of actions in the pot. The term 'hand reading' is actually a misnomer, as skilled players do not attempt to assign a player to an exact hand. Rather they attempt to narrow the possibilities down to a range of probable hands based on the past actions of their opponent, during both the current hand and previous hands played by this opponent.

Tells are detectable changes in opponents' behavior or demeanor which provide clues about their hands or their intentions. Educated guesses about opponents' cards and intentions can help a player avoid mistakes in his own play, induce mistakes by the opponents, or influence the opponents to take actions that they would not normally take under the circumstances. For example, a tell might suggest that an opponent has missed a draw, so a player seeing it may decide a bluff would be more effective than usual.
Leveling or multiple level thinking is accounting for what the other opponents think about the hands. This information can then be used to the player's advantage. Some players might be able to make educated guesses about opponents' hands; this could be seen as the first level. The second level could be thought of as the combination of the first level and deducing what the opponents think the player's hand may be. Skilled players can adjust their game play to be on a higher level than that of less skilled opponents.
Table image and opponent profiling[edit]
By observing the tendencies and patterns of one's opponents, one can make more educated guesses about others' potential holdings. For example, if a player has been playing extremely tightly (playing very few hands), then when he/she finally enters a pot, one may surmise that he/she has stronger than average cards. One's table image is the perception by one's opponents of one's own pattern of play. A player can leverage their table image by playing out of character, and thereby inducing his/her opponents to misjudge his/her hand and make a mistake.
In live poker, as opposed to internet, stereotypes are often used for initial 'reads'. For instance, people of retirement age are often witnessed to play tight. Players will often project this image on unknown people of retirement age. Young people wearing headphones and hoodies are often witnessed to play more aggressively and mathematically if they played a lot of winning internet poker. These stereotypes can often be good bases to start a profile.
Often, there is a rather small pool of players in a given card playing venue. People will carry their history of playing with them in these environments.
Internet poker players can use large databases of hand histories to get a more precise player profile. Statistical information about opponents is displayed on the tables in the form of a heads up display. The most commonly used software is PokerTracker and Hold'em Manager.
Equity[edit]
Players' equity in a pot is their expected share of the pot, expressed either as a percentage (probability of winning) or expected value (amount of pot * probability of winning). Negative equity, or loss in equity, occurs when contributing to a pot with a probability of winning less than 1 / (number of opponents matching the contribution+1).
Short-handed considerations[edit]
When playing short-handed (at a table with 3-6 players), players must loosen up their play (play more hands) for several reasons:[1]

This type of situation comes up most often in tournament style play. In a cash game, the adjustments are very similar, but not quite as drastic as the table can ask for what is known as a 'rake break.' A rake break occurs when the floor-man, who represents the casino, agrees to take a smaller portion than usual for the hand. For example, a random casino might normally receive 10% of the pot up to 5 dollars for a 'rake.' In this case the table would only owe 10% up to 3 dollars until there are a sufficient number of players again. In online poker rake breaks are determined automatically.
Structure considerations[edit]
The blinds and antes and limit structure of the game have a significant influence on poker strategy. For example, it is easier to manipulate pot odds in no-limit and pot-limit games than in limit games. In tournaments, as the size of the forced bets relative to the chip stacks grows, pressure is placed on players to play pots to avoid being anted/blinded away.[5]
Mindset considerations[edit]
In 2014, Bwin conducted a study to see what makes a professional poker player. The brain activity of poker players, of varying degrees, was monitored using EEG headsets and visualised into brain maps.[6] Leading sports psychologist, James Hazlett, then interpreted the findings:
The conclusions of the study suggest that poker players can improve their strategy by considering their mindset. Mental training techniques, commonly used by athletes, could therefore help to improve performance by working on elements such as self-control and concentration.

If I were teaching a new player to play no-limit hold’em, and my goal were to get this player up to a professional level of play, how would I do it? What would my lessons look like?
Let’s say I had only three months to do it. With most people, I will admit, it would be a tall order. The learning curve is steep these days, and I don’t think everyone could make it from zero to pro in that short a time.
I’d have to make compromises. I couldn’t try to cover every possible situation. I’d have to find the important bits and skip the rest.
I’d also have to tailor the lessons a bit to a specific type of game. The most important skills in some game types are not as important in others. With this in mind, here are what I think my top five lessons would be for a new player trying to beat the $2-$5 no-limit hold’em games in Las Vegas.
Lesson No. 1. Don’t limp into pots ever. And don’t call preflop three-bets unless you are trapping with an ultra-premium hand.
Limping into pots, calling the preflop raise, and then check/folding the flop when you miss is an enormous leak. It’s also one that nearly every player who hasn’t been specifically coached out of it exhibits.
In my opinion, most players would see an immediate improvement in their winrates if they simply refused to limp in with any hand, especially if they chose to instead fold most of these hands.
For most players, refusing ever to limp means playing much tighter, particularly from out of position. Until you’re already an established pro player, tighter is better.
Lesson No. 2. Don’t pay off big turn and river bets.
This lesson might be different in some types of games, but in the Las Vegas $2-$5 games, it’s easily a candidate for the single most important piece of advice. Do not pay anyone off. When someone makes a big turn or river bet or raise, your one pair hand (or whatever other hand you’re thinking about calling with) is a bluff-catcher. That means, in the great majority of cases, your opponent won’t be trying to make a value bet with a worse hand. Either you’re beat or your opponent is bluffing. And players in these $2-$5 games do not bluff often enough to make calling worthwhile.
So you don’t pay off. I know it can be frustrating to feel like you’re getting muscled out of a huge pot, but the fact is, most players in these games do very little muscling. They try to make hands, and then they bet the hands they make. A big bet usually means a big hand. You don’t need to call to find out for certain.
Lesson No. 3. Your opponents will limp into pots, call raises, and check/fold flops. Take advantage of this weakness by raising lots of hands with position, betting the flop, and often also betting the turn.
It’s a simple play, but it’s one that generates a very consistent profit in these games. Players play too loosely preflop, are too willing to call preflop raises after limping in, and are too willing to check/fold the flop or turn if they miss. With many players, you can ignore your cards and raise the limps, bet nearly all flops, and bet most turn cards as well.
Say two typical players limp in a $2-$5 game. You raise to $25 on the button. Both limpers call.
The flop comes 10 8 2. They check, and you bet $50. One player calls.
The turn is the 5. Your opponent checks, you bet $120, and he folds.
Lucky club casino online. In this scenario, and in many like it, it doesn’t matter what you have. Your opponents are beating themselves by playing call/call/fold so often. All you have to do is put the bets out there and let your opponents run repeatedly into the brick wall.
Yes, there is some nuance to this, and some boards are better bets than others. But against many opponents at the $2-$5 level, most flops, turns, and even rivers are good bets. Keep betting until your opponents prove to you that they won’t beat themselves by folding too much.

Lesson No. 4. With value hands, don’t try to blow opponents out of pots. Instead, play most value hands with the goal of keeping a player in through the river.
Value hands — hands like top pair, two pair, or any other hand you think is a favorite to be best — lose their value when all your opponents fold. If you win without a showdown, you might as well have been holding 7-2. (See Lesson No. 3.) With your value hands, you generally want opponents to get to the river.
Most players like to see showdowns if they feel like they can see them without losing too much money. No one likes to fold and think, “What if I was good?†If your opponents get to the river, often it’s an easy sell to get them to call a final value bet (as long as you don’t make it too big).
Calling these value bets is one of the biggest mistakes that $2-$5 players make. (See Lesson No. 2.) Allow your opponents to make this mistake.
Most players try to end hands early when they feel like they have the best hand. “Don’t want to get drawn out on,†they think. But this is backward thinking. End hands early with strong bets when you have nothing but a weak draw. Allow hands to reach showdown when you actually have something to show down! (Makes sense when I put it that way, doesn’t it?)
If I have top pair, I’d much rather get called for $30, $50, and $80 on flop, turn, and river than get called for $30 and then blow my opponent out of the hand with a $100 bet on the turn. The chance to win $160 with the hand instead of $30 outweighs the risk that I’ll get outdrawn.
Lesson No. 5. Think every hand about what strategies your opponents are using and how they’re thinking, and (almost) ignore the two cards in your hand.
I’ll put it bluntly. Most $2-$5 players beat themselves. They tend to play strategies that are extremely transparent, overly simplistic, and inflexible. You can beat some of these players simply by betting every time it’s your action (See Lesson No. 3.) You can beat other of these players simply by waiting for hands that beat top pair/no kicker and then making value bets. (See Lesson No. 4.)
Your job as a poker player is to identify the strategy each opponent is using and deploy a counter strategy. In many cases, the two cards in your hand become irrelevant. My experience is that the players that are always thinking about their hands never figure it out. It’s the players who are thinking on the next level that do. â™
