When someone first starts learning about how to play and win at poker, they invariably come across the term “bluffing”. It’s a concept that is quickly recognized but rarely the complexities of why and when you should be bluffing are explained in any great detail.

You also need to realize that there are multiple kinds of bluffs that each should be done with differing levels of frequency. The four main types of bluffs are semi-bluffs, pure bluffs, converted bluffs, and merges. A pure bluff is probably the one you think about when you hear bluff. In the card game of poker, a bluff is a bet or raise made with a hand which is not thought to be the best hand. To bluff is to make such a bet. The objective of a bluff is to induce a fold by at least one opponent who holds a better hand. The size and frequency of a bluff determines its profitability to the bluffer. Bluff Frequency: every opponent has a frequency that they bluff, from 0.0% of the time (never) to 66% of the time (2/3). This is not necessarily apparent to you, unless you see showdowns and can. You want to find a good balance so that your bluffs are believable. If your bluffs are never getting called, you likely aren’t bluffing with enough frequency. I have published an article on Poker Tells, don’t forget to have a look and learn about poker tells when you playing poker. Note that this bluffing frequency means that 40 percent of the time we’re betting, our hand is a bluff. It does not mean that when we are dealt a bluffing hand, we decide to bet 30 percent of the time. However, that doesn’t mean that you should be playing according to these numbers.

Now if you’ve found your way to this article, I’m guessing you already have a basic understanding of what bluffing in poker is all about – so I won’t bore you with the basics.

But what I will offer you is some helpful tips and advice on how to go about this business of bluffing, enabling you to win more pots without a showdown.

Please bare in mind, however, that bluffing really is only a small part of being a good poker player.

It is by no means as significant as popular culture, and movies, make it out to be. But it does have its place in any solid poker playing strategy, and if you want to learn how to win more money playing poker, you’ll do well to learn it.

With this in mind, let’s get to the tips:

1. The first and one of the most important tips when it comes to bluffing is to always be aware of how many players you’re going to try bluffing. You may get away with it if you’re bluffing one player, maybe two, but if you’re playing against a lot of people who are still involved in the pot, then chances are someone will have a strong hand and will just call you on your bluff. A common misconception is that just because you raised the pot before the flop, this means you continuation bet on the flop, even when you miss yourself. This is a big weakness in many beginner poker players’ game, since it doesn’t take into account the flop and the likelihood that it hit one of your opponents. If your pre-flop gets many calls, the chances of a bluff working on the flop is extremely rare, you’re basically burning money.
2. The second tip I have for you is to try and stay away from bluffing people who are much better than you, or much worse than you. Why? Because an expert poker player is much more likely to see through your bluffing because they’re good hand readers and will know the likelihood of whether you will actually have a hand. Similarly, if you’re playing against a really bad player, your bluff is very likely to be called because these types of players don’t know how to fold.
3. As a general rule of thumb, however, you’ve got a better chance with your bluff if the other players have shown weakness after they’ve checked, instead of bluffing when the other players have betted.
4. This next tip is killer and will boost your chances when it comes to implementing a successful bluffing strategy. If you can, always imply specific (and strong) hands when you bluff. In other words, by your bluffing, you are suggesting that you maybe have a strong hand like a flush/straight/three of a kind, which will boost your chances of success considerably. When the board is scary it increases the likelihood that your opponent will fold a medium strength hand. For example, let’s say you called a player’s bet with an open ended straight draw on the flop. You don’t hit your draw on the turn, but a flush is now possible, and your opponent checks, which is usually a good indication they’re giving up on the hand. If you know your opponent is capable of folding, this would be a good spot to bluff with your straight draw, especially if you have an additional flush draw now to go with it, if you expect your opponent to fold their one pair hand, because its very possible you were calling with a flush draw on the flop.
5. A good time to practice your bluffing skills is when all the cards are out, and you don’t have anything in a heads up situation. This is as good a time as any to practice your skills, but remember, don’t overdo it otherwise you’ll become predictable. You want to find a good balance so that your bluffs are believable. If your bluffs are never getting called, you likely aren’t bluffing with enough frequency.

Poker Bluff Frequency Definition

In the card game of poker, a bluff is a bet or raise made with a hand which is not thought to be the best hand. To bluff is to make such a bet. The objective of a bluff is to induce a fold by at least one opponent who holds a better hand. The size and frequency of a bluff determines its profitability to the bluffer. By extension, the phrase 'calling somebody's bluff' is often used outside the context of poker to describe situations where one person demands that another proves a claim, or proves that they are not being deceptive.^[1]

Pure bluff[edit]

A pure bluff, or stone-cold bluff, is a bet or raise with an inferior hand that has little or no chance of improving. A player making a pure bluff believes they can win the pot only if all opponents fold. The pot odds for a bluff are the ratio of the size of the bluff to the pot. A pure bluff has a positive expectation (will be profitable in the long run) when the probability of being called by an opponent is lower than the pot odds for the bluff.

For example, suppose that after all the cards are out, a player holding a busteddrawing hand decides that the only way to win the pot is to make a pure bluff. If the player bets the size of the pot on a pure bluff, the bluff will have a positive expectation if the probability of being called is less than 50%. Note, however, that the opponent may also consider the pot odds when deciding whether to call. In this example, the opponent will be facing 2-to-1 pot odds for the call. The opponent will have a positive expectation for calling the bluff if the opponent believes the probability the player is bluffing is at least 33%.

Semi-bluff[edit]

Poker Bluff Frequency Calculator

In games with multiple betting rounds, to bluff on one round with an inferior or drawing hand that might improve in a later round is called a semi-bluff. A player making a semi-bluff can win the pot two different ways: by all opponents folding immediately or by catching a card to improve the player's hand. In some cases a player may be on a draw but with odds strong enough that they are favored to win the hand. In this case their bet is not classified as a semi-bluff even though their bet may force opponents to fold hands with better current strength.

For example, a player in a stud poker game with four spade-suited cards showing (but none among their downcards) on the penultimate round might raise, hoping that their opponents believe the player already has a flush. If their bluff fails and they are called, the player still might be dealt a spade on the final card and win the showdown (or they might be dealt another non-spade and try to bluff again, in which case it is a pure bluff on the final round rather than a semi-bluff).

Bluffing circumstances[edit]

Bluffing may be more effective in some circumstances than others. Bluffs have a higher expectation when the probability of being called decreases. Several game circumstances may decrease the probability of being called (and increase the profitability of the bluff):

• Fewer opponents who must fold to the bluff.
• The bluff provides less favorable pot odds to opponents for a call.
• A scare card comes that increases the number of superior hands that the player may be perceived to have.
• The player's betting pattern in the hand has been consistent with the superior hand they are representing with the bluff.
• The opponent's betting pattern suggests the opponent may have a marginal hand that is vulnerable to a greater number of potential superior hands.
• The opponent's betting pattern suggests the opponent may have a drawing hand and the bluff provides unfavorable pot odds to the opponent for chasing the draw.
• Opponents are not irrationally committed to the pot (see sunk cost fallacy).
• Opponents are sufficiently skilled and paying sufficient attention.

The opponent's current state of mind should be taken into consideration when bluffing. Under certain circumstances external pressures or events can significantly impact an opponent's decision making skills.

Optimal bluffing frequency[edit]

If a player bluffs too infrequently, observant opponents will recognize that the player is betting for value and will call with very strong hands or with drawing hands only when they are receiving favorable pot odds. If a player bluffs too frequently, observant opponents snap off their bluffs by calling or re-raising. Occasional bluffing disguises not just the hands a player is bluffing with, but also their legitimate hands that opponents may think they may be bluffing with. David Sklansky, in his book The Theory of Poker, states 'Mathematically, the optimal bluffing strategy is to bluff in such a way that the chances against your bluffing are identical to the pot odds your opponent is getting.'

Optimal bluffing also requires that the bluffs must be performed in such a manner that opponents cannot tell when a player is bluffing or not. To prevent bluffs from occurring in a predictable pattern, game theory suggests the use of a randomizing agent to determine whether to bluff. For example, a player might use the colors of their hidden cards, the second hand on their watch, or some other unpredictable mechanism to determine whether to bluff.

Example (Texas Hold'em)[edit]

Here is an example for the game of Texas Hold'em, from The Theory of Poker:

when I bet my $100, creating a $300 pot, my opponent was getting 3-to-1 oddsfrom the pot. Therefore my optimum strategy was ... [to make] the odds againstmy bluffing 3-to-1.

Since the dealer will always bet with (nut hands) in this situation, they should bluff with (their) 'Weakest hands/bluffing range' 1/3 of the time in order to make the odds 3-to-1 against a bluff.^[2]

Ex:On the last betting round (river), Worm has been betting a 'semi-bluff' drawing hand with: A♠ K♠ on the board:

10♠ 9♣ 2♠ 4♣against Mike's A♣ 10♦ hand.

The river comes out:

2♣

The pot is currently 30 dollars, and Worm is contemplating a 30-dollar bluff on the river. If Worm does bluff in this situation, they are giving Mike 2-to-1 pot odds to call with their two pair (10's and 2's).

In these hypothetical circumstances, Worm will have the nuts 50% of the time, and be on a busted draw 50% of the time. Worm will bet the nuts 100% of the time, and bet with a bluffing hand (using mixed optimal strategies):

${\displaystyle x=s/(1+s)}$^[3]

Where s is equal to the percentage of the pot that Worm is bluff betting with and x is equal to the percentage of busted draws Worm should be bluffing with to bluff optimally.

Pot = 30 dollars.Bluff bet = 30 dollars.

s = 30(pot) / 30(bluff bet) = 1.

Worm should be bluffing with their busted draws:

${\displaystyle x=1/(1+s)=50\mathrm{\%}}$ Where s = 1

Assuming four trials, Worm has the nuts two times, and has a busted draw two times. (EV = expected value)

Poker Bluff Frequency Chart

Under the circumstances of this example: Worm will bet their nut hand two times, for every one time they bluff against Mike's hand (assuming Mike's hand would lose to the nuts and beat a bluff). This means that (if Mike called all three bets) Mike would win one time, and lose two times, and would break even against 2-to-1 pot odds. This also means that Worm's odds against bluffing is also 2-to-1 (since they will value bet twice, and bluff once).

Say in this example, Worm decides to use the second hand of their watch to determine when to bluff (50% of the time). If the second hand of the watch is between 1 and 30 seconds, Worm will check their hand down (not bluff). If the second hand of the watch is between 31 and 60 seconds, Worm will bluff their hand. Worm looks down at their watch, and the second hand is at 45 seconds, so Worm decides to bluff. Mike folds his two pair saying, 'the way you've been betting your hand, I don't think my two pair on the board will hold up against your hand.' Worm takes the pot by using optimal bluffing frequencies.

This example is meant to illustrate how optimal bluffing frequencies work. Because it was an example, we assumed that Worm had the nuts 50% of the time, and a busted draw 50% of the time. In real game situations, this is not usually the case.

The purpose of optimal bluffing frequencies is to make the opponent (mathematically) indifferent between calling and folding. Optimal bluffing frequencies are based upon game theory and the Nash equilibrium, and assist the player using these strategies to become unexploitable. By bluffing in optimal frequencies, you will typically end up breaking even on your bluffs (in other words, optimal bluffing frequencies are not meant to generate positive expected value from the bluffs alone). Rather, optimal bluffing frequencies allow you to gain more value from your value bets, because your opponent is indifferent between calling or folding when you bet (regardless of whether it's a value bet or a bluff bet).^[3]

Bluffing in other games[edit]

Although bluffing is most often considered a poker term, similar tactics are useful in other games as well. In these situations, a player makes a play that should not be profitable unless an opponent misjudges it as being made from a position capable of justifying it. Since a successful bluff requires deceiving one's opponent, it occurs only in games in which the players conceal information from each other. In games like chess and backgammon, both players can see the same board and so should simply make the best legal move available. Examples include:

• Contract Bridge: Psychic bids and falsecards are attempts to mislead the opponents about the distribution of the cards. A risk (common to all bluffing in partnership games) is that a bluff may also confuse the bluffer's partner. Psychic bids serve to make it harder for the opponents to find a good contract or to accurately place the key missing cards with a defender. Falsecarding (a tactic available in most trick taking card games) is playing a card that would naturally be played from a different hand distribution in hopes that an opponent will wrongly assume that the falsecarder made a natural play from a different hand and misplay a later trick on that assumption.
• Stratego: Much of the strategy in Stratego revolves around identifying the ranks of the opposing pieces. Therefore depriving your opponent of this information is valuable. In particular, the 'Shoreline Bluff' involves placing the flag in an unnecessarily-vulnerable location in the hope that the opponent will not look for it there. It is also common to bluff an attack that one would never actually make by initiating pursuit of a piece known to be strong, with an as-yet unidentified but weaker piece. Until the true rank of the pursuing piece is revealed, the player with the stronger piece might retreat if their opponent does not pursue them with a weaker piece. That might buy time for the bluffer to bring in a faraway piece that can actually defend against the bluffed piece.
• Spades: In late game situations, it is useful to bid a nil even if it cannot succeed.^[4] If the third seat bidder sees that making a natural bid would allow the fourth seat bidder to make an uncontestable bid for game, they may bid nil even if it has no chance of success. The last bidder then must choose whether to make their natural bid (and lose the game if the nil succeeds) or to respect the nil by making a riskier bid that allows their side to win even if the doomed nil is successful. If the player chooses wrong and both teams miss their bids, the game continues.
• Scrabble: Scrabble players will sometimes deliberately play a phony word in the hope the opponent does not challenge it. Bluffing in Scrabble is a bit different from the other examples. Scrabble players conceal their tiles but have little opportunity to make significant deductions about their opponent's tiles (except in the endgame) and even less opportunity to spread disinformation about them. Bluffing by playing a phony is instead based on assuming players have imperfect knowledge of the acceptable word list.^{[citation needed]}

Artificial intelligence[edit]

Evan Hurwitz and Tshilidzi Marwala developed a software agent that bluffed while playing a poker-like game.^[5][6] They used intelligent agents to design agent outlooks. The agent was able to learn to predict its opponents' reactions based on its own cards and the actions of others. By using reinforcement neural networks, the agents were able to learn to bluff without prompting.

Economic theory[edit]

Poker Bluffing Frequency

In economics, bluffing has been explained as rational equilibrium behavior in games with information asymmetries. For instance, consider the hold-up problem, a central ingredient of the theory of incomplete contracts. There are two players. Today player A can make an investment; tomorrow player B offers how to divide the returns of the investment. If player A rejects the offer, they can realize only a fraction x<1 of these returns on their own. Suppose player A has private information about x. Goldlücke and Schmitz (2014) have shown that player A might make a large investment even if player A is weak (i.e., when they know that x is small). The reason is that a large investment may lead player B to believe that player A is strong (i.e., x is large), so that player B will make a generous offer. Hence, bluffing can be a profitable strategy for player A.^[7]
