How do you calculate variance in poker?

What is variance? – Variance is the downswings and upswings involved with playing poker. It’s quite possibly the least technical definition for a term I have ever written, but the “ups and downs” of poker when it comes to winning and losing money sums it up rather well.

What is standard deviation in poker?

What is Standard Deviation in Poker? Quick Answer – Standard deviation in poker is a value expressed in bb/100 (i.e. a winrate) that helps us understand how ‘swingy’ our poker game is. Understanding how the value is calculated is not imperative; we can use poker tracking software to calculate the vale for us.

Is there an algorithm for poker?

Algorithm – The algorithm is a numerical approach to quantify the strength of a poker hand where its result expresses the strength of a particular hand in percentile (i.e. ranging from 0 to 1), compared to all other possible hands. The underlying assumption is that an Effective Hand Strength (EHS) is composed of the current Hand Strength (HS) and its potential to improve or deteriorate (PPOT and NPOT): E H S = H S × ( 1 − N P O T ) + ( 1 − H S ) × P P O T where:

E H S is the Effective Hand Strength H S is the current Hand Strength (i.e. not taking into account potential to improve or deteriorate, depending on upcoming table cards N P O T is the Negative POTential (i.e. the probability that our current hand, if the strongest, deteriorates and becomes a losing hand) P P O T is the Positive POTential (i.e. the probability that our current hand, if losing, improves and becomes the winning hand)

What is the most popular variation of poker?

Thanks to televised events like the World Series of Poker, the game of poker has risen in popularity in recent years. Players are attracted to the game’s combination of psychology, probability and, of course, luck in trying to put together winning hands time after time.

1. If you visit a casino, you’ll notice that there are multiple different types of poker, each with slight rule variations that change the complexity and the strategy of each game.
2. Here are five common types of poker you’re likely to see played at a casino,1.
3. Five Card Draw Considered one of the simplest forms of poker, five card draw starts with each player receiving five cards.

After the initial deal, players can choose up to three cards to trade in exchange for new cards. The player with the best five-card combination wins.2. Texas Hold ’em By far the most popular version of poker played in America, Texas Hold ’em is the version of poker played in the World Series of Poker.

The game starts with each player receiving two cards to keep to themselves, and then progresses as five community cards are laid onto the table.1 “Players bet a total of four times during the game: after each player receives to cards, then three more times as the community cards are laid on the table,” says a spokesperson for The Casino at Dania Beach,

“Players use a combination of their own two cards and the five community cards to put together the best five-card combination possible, with the best overall combination winning the hand—and the chips.” 3. Omaha Hold ’em This variant of poker looks a lot like Texas Hold ’em, with two importance differences.

First, players are dealt four cards instead of two at the start of the hand. And the five community cards are all turned over at the same time, instead of being spread out over three rounds. However, players can only use two of their own cards when putting together the best five-card combination.4. Seven Card Stud In this game, each player is dealt seven cards.

Three are face down, and four are face up and visible to the entire table. Players use those seven cards to create the best five-card hand possible. “Compared to a game like five card draw, seven card stud can feature more dangerous hands since players have seven cards to choose from, instead of five,” says a spokesperson for The Casino at Dania Beach, 5. Video Poker If you ask a poker enthusiast, video poker is not the same as a regular poker game. With this machine-based version, there are no other players—you’re only playing against the computer to put together the best hand possible. It’s not the same as the real thing, but if you find yourself overwhelmed at the live poker tables, it might be worth taking a break for the relatively lower-stakes, lower-stress experience offered by a video poker machine.

What is the 3 standard deviation rule?

What Is the Empirical Rule? – In statistics, the empirical rule states that 99.7% of data occurs within three standard deviations of the mean within a normal distribution. To this end, 68% of the observed data will occur within the first standard deviation, 95% will take place in the second deviation, and 97.5% within the third standard deviation.

What is a good sample size in poker?

What is a Good Sample Size in Poker? – This is an incredibly difficult question to answer because there are so many different factors to consider. These factors include whether you are playing cash games or tournaments, live or online, deep stack or short stack, heads up or full ring, and so on.

You should never be reading into anything below a sample size of 10k hands, At around 10k hands, your win rate will typically be true within ±8bb. Although this is better than nothing, it is still a huge margin of error. The next point of consideration is 30k hands, At 30k hands, your win rate is likely within ±6bb of your true win rate. Generally, 30k hands are the minimum sample size that most players will use to even begin to consider whether or not you are a winning player. At 100k hands, your win rate is likely within ±4bb of your true win rate. This is often the number of hands you will hear online players say you need to obtain before you can actually determine your true win rate. For good measure, we have previously mentioned that to determine your win rate, you should aim to have a least 250k hands. At 250k hands, you are most likely to be within ±2bb of your true win rate.

In terms of HUD stats, the answer is more complicated. Some poker players will attempt to make very basic conclusions on opponents’ leaks at around 50 hands. These will be incredibly basic insights, however, based on similarities to other players within the population.

1. Ideally, in most cases, you should have at least 200 hands before making any decisions about an opponent’s leaks.
2. However, this again depends on the context.
3. For example, 200 hands on a cash game player is far more meaningful than an MTT player who has to deal with constantly increasing blind levels.
4. Overall, it is just simply impossible to pinpoint any good minimum sample size in terms of HUD stats for all game types.

Each game is unique and requires it’s own considerations when determining a good minimum sample size.

A small SD represents data where the results are very close in value to the mean. The larger the SD the more variance in the results. Data points in a normal distribution are more likely to fall closer to the mean. In fact, 68% of all data points will be within ±1SD from the mean, 95% of all data points will be within + 2SD from the mean, and 99% of all data points will be within ±3SD. Statisticians have determined that values no greater than plus or minus 2 SD represent measurements that are are closer to the true value than those that fall in the area greater than ± 2SD. Thus, most QC programs require that corrective action be initiated for data points routinely outside of the ±2SD range.

What is the 7 2 rule in poker?

The 7-2 Game A few nights ago I had the chance to play at friend’s home game where we implemented the 7-2 game. For those of your not familiar, this is where anytime a player wins with 7-2, every other player at the table has to give them some amount of money.

In our case, we were playing a deep-stacked 1/2 game with six players and when someone won with 7-2, they would get $10 (5 BB) from every other player.25 BB total is not a bad score, especially when you’re able to take it down preflop. Some people hate the game, others love it, and I certainly fall into the later category.

Anything to drum up action and encourage bluffing is a win in my book. At first, it no one was getting dealt 7-2. After at least four orbits the hand was not shown down and everyone said they hadn’t seen the had once. This makes sense though- of the 1326 possible starting hand combos in NLHE, 7-2 comprises only 16 of them, for a little over 1% of total possible hands.

After about an hour though of no one getting the hand, seemingly all at once, a very high proportion were getting dealt, and this continued for the rest of the night. There were at least 4x as many 7-2 combos dealt as what one would expect based on the odds (I certainly wasn’t complaining about that!).

While the game is normally fun, somewhat loose, with a good amount of aggression, the 7-2 game transformed the table to have a preflop aggression frequency higher than the toughest online 6max games. It seemed like there was a 3bet every few hands with no one ever really choosing to back down with 7-2.

• On top of the standard 3 and 4bet bluffs with 7-2, there were also a few notable pots where 7-2 triple barreled on a scary board and got called down on all three streets and where a player opted to flat with 7-2 preflop and make a series of bluffs postflop to take it down.
• For the home game that this was played in, I think the 7-2 game makes a lot of sense.

Everyone could afford to play these stakes so although the hyped up aggression left some people frustrated by the end of the night, it wasn’t going to make anyone not come back. The only scenario in which I could see the 7-2 game not making sense for one’s home game is if the stakes being played are meaningful to some, and the thought of losing 3 buyins or more in a friendly game is something that would discourage players from coming back (although in this type of case, my recommendation would be to lower the stakes, up the stack depth, and bring on the preflop aggression!).

What I’m excited to further explore is not the merits of whether or not to play the 7-2 game sometimes – unless you hate action and people bluffing more, it’s worth at least trying for an hour or two. I want to look at how this game effects decisions so if you find yourself in a game where people are playing the 7-2 game, you know how to adjust.

I think it’s fairly obvious for those that have played the 7-2 game, most people over-adjust and bluff too much when holding 7-2. I’m going to look at how the reward of winning a hand wth 7-2 impacts one’s EV and your frequencies. For the sake of simplicity, let’s work with the assumption that the reward for winning with 7-2 is 30 BB – 5 BB at a 7 handed home game.

Let’s say you normally open 3 BB to win 1.5 BB. Now with the 7-2 game in play the reward is 31.5 BB. So it’s clear even in early position 7-2 is a slam-dunk open. Now what about a 3bet? Let’s say you standardly 3bet to 10 BB over a 3 BB open. So now instead of risking 10 BB to win 4.5 BB, you’re risking 10 to win 34.5 BB.

At first glance it might seem like we should be 3betting 100% of the time with 7-2. I think in most games this is probably correct, but if you’re in a really loose game where people rarely fold to 3bets, or up against a particularly sticky player, it might be best to just fold against those type of players.

1. Because once called preflop, 7-2 has such poor equity against a calling range so without much fold equity postflop, best to just fold pre.
2. Note in these games I would have a tiny or non-existent 3bet bluffing range without the 7-2 game.
3. Most players will have a frequency that they fold to 3bets, even in a loose, aggressive, and deep stacked game, so most of the time you should replace some of your 3bet bluffs with 7-2.

The key when adjusting for this game is not completely throw off your relative frequencies – if you normally 3bet in late position with 9s+ AQ+ for value and A2s-A5s as a bluff, don’t just add 7-2 to your 3betting range unless these players won’t adjust to the 7-2 game – almost no one doesn’t adjust when playing the 7-2 game, if anything, most players in my experience over-adjust and always “put you on 7-2”.

So against most players you should also add at least the proportionate amount of value combos to keep your ratio of value hands to bluffs the same, if not more value hands due to overadjustment. Now on to 4bet bluffing. If a standard 4bet to a 10 BB 3bet is 35 BB, you’re normally risking 35 BB to win 11.5 BB, and with the 7-2 game to win 41.5 BB.

As you can see, after more preflop betting occurs, you’re starting to risk more to win relatively less. The same logic for when to 3bet bluff with 7-2 applies to 4betting, although because of the price we’re laying ourselves, we need to be a little more conservative than with 3betting.

• Against a relatively balanced player, we should be 4bet bluffing all combos of 7-2.
• But against someone who only 3bets very good hands or is looking to gamble with a merged value range, best to fold all combos of 7-2 preflop.
• I imagine there aren’t many opponents where it is correct to do anything but fold all combos or 4bet all combos.

It would take a particular opponent who is somewhat balanced in their 3betting range but a little too loose to warrant a mixed strategy with 7-2. Postflop Barreling frequencies with 7-2 postflop are largely dependent on the size of the pot after the preflop betting.

In a similar fashion to preflop, it’s likely correct to cbet 100% in a single-raised pot heads up- if our cbet sizing is on average 1/2 pot, then one is risking 3.25 BB to win 37.5 BB. With multiple players in the pot, it still is likely correct to cbet 100% with 7-2 because of the price. Even if the 3.25 BB cbet only gets through 15% of the time in a 4way pot, it’s still a really profitable cbet because you’re risking 3.25 BB to win 43.5 BB (only needs to work about 7.5% of the time to break even).

If you’re at a table where it’s so loose that cbets don’t go through on the flop when playing the 7-2 game because everyone puts you on it, don’t ever bluff postflop with 7-2 and please let me know if you ever need another player for the game. In a 3bet pot, the same logic largely applies.

In a heads up pot when cbetting the flop you’re risking 10 BB to win 51.5 BB, so you only need the bet to work 18% of the time as opposed to the normal 33% without the 7-2 bonus. Note how much more of an attractive proposition cbetting is in a single-raised versus heads up pot: cbets only need to work 8.5% of the time versus 18% of the time.

And for 4bet pots this then changes to 26.5% which while is better than the 33% that it would need to work without the 7-2 game, won’t change your range as significantly. In a 4bet pot you should probably give up with some combos of 7-2 and replace your worst normal bluffing candidates with 7-2.

• Don’t be the guy that makes the hero triple barrel – on each street the extra 30 BB becomes much less of a factor.
• If it’s a 3bet pot heads up pot with 200 BB stacks to start the hand, and you get to the river with 100 BB in the pot and 150 BB behind.
• You decide to overbet the river and risk 150 BB to win 100 + 30 BB because goddamnit if you’ll lose with 7-2.

Normally you would need this bluff to work 60%. But with the extra 30 BB, this bet still needs to work 53.5% of the time, not that significant of a difference. If you decide it makes sense to have an overbetting range on a particular river card, it will likely make sense to include at least a combo or two of 7-2, just not all 12 combos.

• Equity when called + fold equity – bet when called and miss + bounty equity = 0
• Equity is when called = x
• % Opponent folds = y
• 7-2 Bounty = z
• So let’s say I bet 50 into 100 on a flop in a heads up pot.
• So the base equation before knowing our exact hands, equities, and bounty is the following knowing the size of the bet:
• x(1-y)*200 + y*100 – 50*(1-x)(1-y) + z = 0
• The flop is Kc6h9c.
• Which is a better c-bet bluffing candidate, 72o or J10c?

Let’s approximate that 7-2 has about 5% equity against a continuing range and J10c has 35% equity. Your opponent will fold 33%, 8% more than optimal. In the home game I played, the 7-2 bounty was 50.7-2,05(1-.33)*200 +,33*100 – 50*(1-.05)(1-.33) + 50 = 57.875 J10c,35(1-.33)*200 +,33*100 – 50*(1-.35)(1-.33) + 0 = 58.125

1. So in this case, we’d expect to profit about $7 (answer of equation – the bet) with our best bluffing candidate as well as 72o betting half pot in a medium sized pot for the stake, without much theoretical difference between the two hands.
2. Now let’s look at what happens if this flop was bet called and a blank turn comes out.
3. Kc6h9c4s

Which is a better bluffing candidate now for betting 140 into 200? Let’s adjust the base equation for this bet and pot size, how often your opponent folds (33%, a few % less than optimally against this bet size), and updated equities – 0% for 7-2 and 18% for J10c.

x(1-y)*480 + y*200 – 140*(1-x)(1-y) + z = 0 7-2 0(1-.33)*480 +,33*200 – 140*(1-0)(1-.33) + 50 = 117 J10c,18(1-.33)*480 +,33*200 – 140*(1-.18)(1-.33) + 0 = 201.796 As you can see, as the pot gets bigger, 7-2 becomes significantly worse (EV of -$23 in this example) to bluff compared to good draws (one would expect to profit $61 semibluffing J10c here).

Now a note on river play – if you do get to the river with 7-2, then it becomes your best bluff because none of your bluffs have equity but you get the extra bounty with 7-2. This doesn’t necessarily mean that you should always bluff with all combos of 7-2 you get to the river with, but you should defintely bluff all 7-2 combos before adding other bluffs.

• Conclusion The big takeaway is to still be quite aggressive with 7-2 – the extra 30 BB in most circumstances makes it an excellent bluffing candidate.
• This becomes less and less true on later streets, and in bloated pots.
• Just remember to not get too crazy and have it make your ratio of value bets to bluffs go out of whack – with the addition of 7-2 to a bluffing range, remember to value bet extra thinly.

Is poker a 100% skill?

There are many people out there who scoff at the thought of playing poker, deriding it as a simple game of luck, just like all other casino games, such as roulette and slots. To put it bluntly, however, these people are entirely wrong and don’t understand the finer points of the game – the finer points that allow a player with skill the chance to gain a huge upper hand over their opponents.

• Poker is a game that combines elements of both skill and chance.
• While the outcome of each hand is determined by the cards that are dealt, players can use their knowledge, experience, and strategies to increase their chances of winning.
• This means that poker is not purely a game of chance like some other forms of gambling, such as slot machines or roulette.

However, it is also important to note that the element of chance is still a significant factor in poker. Players can have the best hand and the best strategy, but they can still lose if they are dealt poor cards or if their opponents make unexpected moves.

As a result, some people consider poker to be more of a game of chance than a game of skill. Overall, the question of whether poker is a game of skill or a game of chance is a complex one, and it depends on how you define these terms. Some people believe that poker is primarily a game of skill, while others believe that it is more of a game of chance.

Ultimately, the answer may depend on individual perspectives and experiences. There are also others, most often poker evangelists with an unwillingness to admit the truth, who state that poker is a game based entirely on skill. The thing is, they’re also wrong, as the game is actually a mixture of skill and luck – an intoxicating fusion of a player’s ability to make the most of their cards, with fortune’s fickle mind helping and hindering players in equal measure.

Can you mathematically win poker?

When is Poker Mathematics used? – Poker players mainly use poker mathematics to decide if it is worth betting and chasing a card to make a winning hand. There are two elements that help them make this decision:

The number of Outs they have ( the number of cards that can make a winning hand) and what is the probability that an Out will be dealt.Calculating the Pot Odds to determine the amount they will win for betting on the Out that will be dealt.

The players compare the chances of them hitting one of the Outs against the Pot Odds and determine whether it will be a good bet. For instance, if you have A♣️ and 8♣️ in the big blind and everyone folds but the small blind calls an extra 5c making the total pot before the Flop equal 20c (2 players x 10c).

1. Then in the flop, K♣️9♦️4♣️ are dealt, and the opponent bets 10c.
2. This is where a player would use poker math to decide whether to call or not.
3. Another example of how essential poker math is for poker players is using poker math to analyse the strength of an opponent’s hand.
4. When you are judging the strength of the cards in your opponent’s hand, there may be a possibility that the opponent is bluffing and you have a stronger hand.

Assuming that the opponent bluffs one time for every three times they have the best hand on the river, it means;

There is a 3 in 4 chance that the opponent has a better hand in that round.There is a 3 in 4 chance that you don’t have the stronger hand.There is a 1 in 4 chance that your hand is better than the opponent’s hand.Your chance of winning the hand is 3 odds to 1 or 3:1. This means that you will win 1 time for every 3 times that you lose.

What hand is unbeatable in poker?

Straight Flush: Five cards in numerical order, all of identical suits. In the event of a tie: Highest rank at the top of the sequence wins. The best possible straight flush is known as a royal flush, which consists of the ace, king, queen, jack and ten of a suit. A royal flush is an unbeatable hand. Four of a Kind: Four cards of the same rank, and one side card or ‘kicker’. In the event of a tie: Highest four of a kind wins. In community card games where players have the same four of a kind, the highest fifth side card (‘kicker’) wins. Full House: Three cards of the same rank, and two cards of a different, matching rank. In the event of a tie: Highest three matching cards wins the pot. In community card games where players have the same three matching cards, the highest value of the two matching cards wins. Flush: Five cards of the same suit. In the event of a tie: The player holding the highest ranked card wins. If necessary, the second-highest, third-highest, fourth-highest, and fifth-highest cards can be used to break the tie. If all five cards are the same ranks, the pot is split. The suit itself is never used to break a tie in poker. Straight: Five cards in sequence. In the event of a tie: Highest ranking card at the top of the sequence wins. Note: The Ace may be used at the top or bottom of the sequence, and is the only card which can act in this manner. A,K,Q,J,T is the highest (Ace high) straight; 5,4,3,2,A is the lowest (Five high) straight. Three of a kind: Three cards of the same rank, and two unrelated side cards. In the event of a tie: Highest ranking three of a kind wins. In community card games where players have the same three of a kind, the highest side card, and if necessary, the second-highest side card wins. Two pair: Two cards of a matching rank, another two cards of a different matching rank, and one side card. In the event of a tie: Highest pair wins. If players have the same highest pair, highest second pair wins. If both players have two identical pairs, highest side card wins. One pair: Two cards of a matching rank, and three unrelated side cards. In the event of a tie: Highest pair wins. If players have the same pair, the highest side card wins, and if necessary, the second-highest and third-highest side card can be used to break the tie.

What is the formula for calculating a variance?

Formula for Sample Variance – The variance of a sample for grouped data is:

s 2 = ∑ f (m − x̅) 2 / n − 1

• Where,
• f = frequency of the class
• m = midpoint of the class
• These two formulas can also be written as:

Population variance	Sample variance
Here, σ 2 = Variance x i = Midvalue of ith class f i = Frequency of ith class N = Total number of observations (Population size)	Here, s 2 = Sample variance x i = Midvalue of ith class f i = Frequency of ith class n = Sample size (or Number of data values in sample)

Try: Summary:

Variance Type	For Ungrouped Data	For Grouped Data
Population Variance Formula	σ 2 = ∑ (x − x̅) 2 / n	σ 2 = ∑ f (m − x̅) 2 / n
Sample Variance Formula	s 2 = ∑ (x − x̅) 2 / n − 1	s 2 = ∑ f (m − x̅) 2 / n − 1
