Что такое коин флип
Коинфлип
Особенностью покера можно назвать то, что не существует какой-то единой стратегии игры в покер или, может быть, способа, чтобы одержать победу в конкретной раздаче. Все зависти от игрока и от того выбора, который он сделает в каждой определенной ситуации.
Иногда, даже применяется анализ ситуации с помощью системы под названием – коинфлип в покере, то есть, дословно, бросок монеты. Коинфлип в покере применяется, когда шансы у обоих игроков на выигрыш практически равны, то есть примерно по пятьдесят процентов. Но, поскольку, случаи, когда шансы на победу абсолютно равны, в покере почти не встречаются, то коинфлипом называется даже такая ситуация, когда эквити игроков соотносятся, как сорок пять на пятьдесят пять процентов. В данном случае, сорок пять процентов – будет называться минусовым коинфлипом, а пятьдесят пять процентов – плюсовым, соответственно.
Мнения по тому, как играть коинфлип, среди профессиональных игроков разделились. Например, Ховард Ледерер говорит, что не стоит часто избегать коинфлипов, тем более, когда в банке находится значительное количество фишек. Например, если в поте уже есть тысяча фишек и вы докладываете еще пятьсот для продолжения раздачи, то вкладываете в соотношении два к одному, и такую ситуацию не стоит игнорировать, так как два к одному, как показывает коинфлип в покере, это хороший показатель, если даже есть всего сорок шесть процентов на выигрыш. Или, вот еще мнение Криса Фергюсона, который старается не ввязываться в коинфлипы, однако не видит препятствий в этом, если считается, что противник – хороший игрок, который может навязывать свою игру после флопа. И если у такого игрока выиграть, то будет возможность далее оказывать на него свое давление, особенно при создании положения, когда он сам не захочет разыгрывать коинфлип.

Коинфлип
Материал из Poker-wiki.ru, свободной энциклопедии по покеру.
Коинфлип (англ. Coinflip — дословно, бросок монеты) — ситуация в покере, когда шансы обоих игроков на победу практически равны. Название произошло от игры в бросание монеты, где каждый игрок имеет примерно 50% на выигрыш.
Поскольку абсолютно равные шансы на победу в покере встречаются довольно редко, коинфлипом принято считать ситуации, где соотношение эквити игроков не превышает 45%/55%. При этом, для первого игрока (имеющего 45% на победу) это будет минусовый коинфлип, а для второго (с 55% на победу) — соответственно, плюсовый коинфлип.
Это классический пример коинфлипа, так как игрок 1 имеет 53,5% шансы на победу и 46% на проигрыш со своей стартовой рукой, оставшиеся 0,5% отводятся на сплит. Игрок 2 соответственно имеет 46% шансы на победу, в случае если поймает один из 6 своих аутов на усиление руки (А, K, стрит, либо флеш). Для игрока 1 этот коинфлип плюсовый, а для игрока 2 — минусовый.
Коинфлип и дисперсия
Чаще всего, коинфлип получается, когда один из игроков идет ва-банк, а второй коллирует его ставку. При этом самый распространенный коинфлип — две оверкарты против карманной пары.
По своей сути, коинфлип является околонулевым решением, которое становится слабоотрицательным на длительной дистанции из-за рейка. Вместе с тем, если мы играем олл-ин и получаем при этом коинфлип, наше математическое ожидание на длительной дистанции равно нулю, однако в краткосрочной перспективе мы «раскачиваем» дисперсию на целый размер нашего стека. Поэтому, если стремиться к малодисперсионной игре, коинфлипов стоит избегать.

Что мы знаем о коинфлипах?
На что мы можем ответить:
- Когда случается? Коинфлип происходит тогда, когда при выставление у вас и у противника равные шансы на победу и составляют примерно 50%. Отличный пример – это выставление карманной пары против двух овер карт:
Так что проиграв такую раздачу, вам будет казаться, что это переезд, но на самом деле это лишь выставление 50 на 50.
На что мы не можем ответит
- Когда уже закроют нам? Как мы писали ранее, коинфлип это математически просчитанный спот, где выигрывать вы будет ровно столько же раздач, сколько и проигрывать. Но наш мозг приучен больше запоминать плохого. Игроками во время катки принято воспринимать, что когда вы выиграете монетку, то так и должно быть. А в случае, когда коинфлип выигрывает противник – то это жесткий кулер и бед бит. И вообще этот покер несправедлив. Так что всегда будет казаться, что монетки чаще закрывают вашим противникам чем вам. Особенно обидно, когда проиграете несколько таких раздач подряд.
Сегодня мы разобрались с вами с коинфлипами. Желаем, что бы вы всегда тащили монетки и хорошего настроения.

Coin Flip and Coin Toss
Coin flip and coin toss is essentially the practice of tossing a coin up in the air and guessing which side will land face up. There are just two outcomes, heads or tails.
When the coin is thrown in the air, it should rotate several times before landing on the ground, or caught and inverted by a chosen person. The parties select their prediction by calling out heads or tails either before the coin is tossed, or when it is spinning in the air.
Once the coin comes to a complete rest, the party who guessed correctly is declared the winner.
In rare circumstances, the coin may land on its edge, yet the chances of this happening are somewhere around 6,000:1, and the online coin flip simulator does away with this slim possibility. However, in this case, the coin is generally re-flipped.
There is also a Three-Way coin flip which consists of choosing two correct outcomes out of three throws, or one correctly predicted outcome. The three-way flip offers a 75% likelihood each time it is tried and does not require players to call out heads or tails.
Tossing a coin is also a simple, fair and unbiased way of settling disputes or deciding between more than one arbitrary option. The game has been analyzed extensively and provides both sides with even odds. It requires little effort and prevents disputes from escalating further, possibly into a struggle.
Heads or Tails and the history
The game of Heads or Tails has an exciting and checkered history. Throughout the ages, flip a coin game was used to decide who goes to jail or not, to others it meant a life or death outcome.
The history books would be somewhat different without the influence of the simple game of chance, Heads or Tails. The historical origin of the game is the interpretation of the chance outcome of a coin toss as an expression of the divine or holy.
In ancient China, the game was known as Ship or Head. Coins then depicted a ship on one side, with the head of Elean on the other side.
In England, the game was initially referred to as cross and pile. The Heads or Tails expression results from the head and the tails considered as complementary body parts.
The earliest known references to the game Heads or Tails originate way back in 600-527 BC in Ancient Greece.
The game was referred to as The Shell Game or the Ostrakinda. Plato may offer a clue by mentioning Ostrakinda in the same context as ascension, replacing the soul’s darkness with bright light.
Coin Toss in Sports
Coin tossing has a long history of association with sports. Athletes gather in various sports to flip a coin, before or during a game.
There have been some extremely high profile coin tosses over the years. Results and outcomes of diverse sports from the FIFA Soccer World Cup to the Super Bowl have not escaped the dreaded flip of a coin! A coin toss is typically used to decide arbitrary factors.
Coin Toss in Super Bowl
Like in other football games, a coin flip in Super Bowl decides the kicking and receiving team for the day.
It’s also fair to say that many Super Bowl victories have been foreseen by a cointoss. Terry Bradshaw would have been a Chicago Bear were it not for a coin landing on heads. The Pittsburgh Steelers would not have won the most Super Bowl trophies in NFL history.
The flip of a coin has decided Super Bowl results more times than one can imagine. Preference by head coaches nowadays is to receive after successfully winning the coin toss.
However even if the coaches prefer getting the ball first in the second half of Super Bowl – this doesn’t mean it will lead to a great comeback! Out of 52 Super Bowls, only 25 times the winner of the coin toss went on to win the big one.
While we have had a Super Bowl era of 52 games the stats in the coin flip stand as so:
Latest Super Bowl Coinflip between Patriots and Falcons ended in Heads, braking the 4 times Tails streak. Are you a betting man? What will we see in the next one?
Coin Toss in Football
A coin toss is actually what we tend to miss in a typical broadcast of a football game. We see the kick-off and who is receiving but actually before this the captains gather for the coin flip to decide. Other option is to see a coinflip when a match goes to overtime. Same procedure happens then as well.
Coin toss before the game ultimately decides who will kick off the ball and who will receive. But wait! There is more to the coin toss than that. The team captain of away team gets to choose heads or tails. Winner actually has more than one choice to make!
The winning team of the coin toss can choose either to:
- Kick or to receive the opening kickoff
- Which side to defend
- Defer
Some of these decisions could favor one side over the other or might be neutral. Factors such as the setting sun at one end of the field of play might be a distraction and disadvantage.
We have seen some serious “fumbles” in the cointoss before football games. Legendary one happened in the 1998 Thanksgiving game between the Pittsburgh Steelers and Detroit Lions. Captains gathered around the referee Phil Luckett and following happened:
Steelers captain Jerome “The Bus” Bettis clearly calls as the visiting team “TAILS” but ref picks up that he called “HEADS”.
Sure enough tails land and what ensues is legendary. Ultimately Detroit keeps the cointoss win the game and chose how to start the game. NFL doesn’t allow embedding the video but you can see the full video of the Thanksgiving game 1998 between Steelers and Lions here.
Till today, tossing remains the method of choice most used for arbitrary decisions in American football. Since the NFL playoffs 2018-2019 conversation around the coin toss starting overtime has been a major topic of discussion.
Should the format be changed? The coin is not to be blamed however. Both conference finals during the 2018-2019 NFL playoffs ended up in overtime. While Patriots won the toss and finished the game with first possession touchdown against Chiefs. Elsewhere Saints won the flip of a coin against the Rams, stalled and Rams took it to the house with a 50+ yard field goal.
Coin Toss in Soccer
With Football Association (FA) soccer matches, before extra time, the team that wins the coin toss gets to choose which goal to attack during the first half of, and the opposing team kicks off that first half. Factors such as the direction of the wind and the position of the sun may affect such a decision.
The captain typically makes the call with the referee overseeing and the opposing team captain witnessing the event as well. Furthermore, coin tosses are used to decide which team gets to shoot first in a penalty shootout. Before the 1970s, a coin toss was used to determine the result of a tied result.
Coin Flip in Poker
Even though the flip of an actual coin has a 50/50 chance of reaching one of the two outcomes, the term is used in poker less stringently.
In Texas Hold’em, during heads-up play, a pocket pair has a slightly better percentage against two overcards. The exact amount of the advantage varies and generally depends on if the overcards are suited, or if the cards used in the pocket pair are in the correct range to help the overcards complete a straight. In poker, this situation is considered a coin flip.
Coin Flip in eSports – CS GO coin flips and Heartstone
In the world of eSports flipping a coin is used to decide random but necessary events. Coin flips in eSports can refer to a few different cases in the most popular games in the eSports universe.The now very popular online card video game Heartstone, based on the Blizzard Entertainment “Warcraft” -series uses coinflip to decide which player starts the game.
In Heartstone coin decides which player goes first and draws three starting cards. The losing party of the Heartstone coin flip gets “The Coin” -card which is special to the game of Heartstone. So there are tactical benefits in losing the random coinflip in Heartstone as well.
While you can just flip a coin to decide who goes first in Heartstone, CSGO skin betting also offers one of a kind style of coinflip. Other than that, many situations in eSports and console games in general create the need for a coinflip. Why not use ours!
CSGO coin flip
CSGO coin flip refers to gambling your skins, that you have earned in CS GO video game againts another person. In the CSGO coinflip you choose the skins, inventory or items you want to gamble and enter into a flip against another person for the skins, inventory or items of the same value.

Two up – the Australian tradition to flip a coin
Two up is a version of a coin flip game that is specific for Australia. The name Two up, also written as “Two-up”, hints already that two coins are flipped. The target of the game is to guess, or bet, whether the two coins land with either both heads up, or both tails up. Or if they land with one heads and one tails.
The traditional game of Two up is usually played in pubs on Anzac Day everywhere in Australia, even though legally it is only allowed to play in New South Wales on three days: Anzac Day, Victory in the Pacific Day and Remembrance day.
Anzac day is the national day of remembrance to all Australian and New Zealanders who died while serving in wars and other conflicts, as well as peacekeeping operations.
In Two up, two coins are placed in a small piece of wood, called “kip”. The person running the game is called “boxer”, and he/she chooses a “spinner” who will toss the coins at least three meters in the air.
Both coins have fall inside a circle, otherwise there will be a new toss. Usually in Two-up the coins are tossed until both coins land either on heads or tails. If this doesn’t happen in five tosses, the spinner if often changed.
Flip a coin – a glance into the history
Flip a coin, or heads or tails, has a long and interesting history. We have gathered below some of the most interesting events in which a flip of a coin has played an interesting part in the books of history. Some of which most probably have had an impact to the world we live in right now.
Coin Tossing in Ancient Rome
Julius Caesar made the unorthodox decision of using the flip of a coin to come to a conclusion. This became known as flipism. Around 49 BC, Julius Caesar returned to Rome and began to mint coins bearing his name.
Whenever Caesar was presented with an unclear decision where the right and wrong were blurred, he would flip a coin. Under Caesar’s rule, the practice was taken much more seriously and started to be used for marriage, property, and criminal disputes.
A coin flip subsequently became a legally enforceable decision. Throughout history, the opposite side of the coin, known as tails, was associated with humanism and evil. It may even be a subliminal reference to the serpent’s tail, a symbol often associated with evil and darkness.
Heads or Tails in the USA: The Formation of Portland, Oregon
Eventually, Heads or Tails found its way to the USA. In 1845, two individuals had an issue how to name a new town that bordered their own land.
They both owned large tracts of land, and landowners Asa Lovejoy and Francis Pettygrove were deadlocked. The decision was made with a coin flip, Pettygrove won the toss, and the town of Portland, Oregon, USA was born.
Lovejoy and Pettygrove actually decided the use the format of best of three flips. In this format you have to win two flips to win the whole thing.
Wright Brothers Maiden Transatlantic Flight
Another monumental coin flip was between brothers Wilbur and Orville Wright in 1903. They tossed a coin into the air to see who would be the first to take the maiden flight.
Wilbur won that toss but failed on his first attempt. By a peculiar twist of fate, It was eventually Orville who made it instead!
Ritchie Valens, Buddy Holly & The Big Bopper
In 1959, rock n roll legends Ritchie Valens, “The Big Bopper” Richardson and Buddy Holly were all killed in a plane crash.
Rumour has it that Valens won a coin toss with a band member Tommy Allsup for the remaining seat. The plane they were on crashed in a cornfield close to Clear Lake, Iowa USA. They were all killed on that fateful flight.
Probability of a Coin Flip
The general perception is the outcome of a coin flip is bound to be 50/50. This prediction relies on the premise that the coin is fair, and heads and tails are equally likely.
The probability that a coin lands on either side is 50%. A coin can be checked if it is fair by tossing it a large number of times and noting the number of heads that come up each time. For instance, throw a coin 100 times and check how many heads or tails turn up. If the heads turn up 55 times out of the total 100 tosses, then the ratio is 55/100, or 0.55.
This system of calculating probability is named “relative frequency estimate of a probability”, and it is a straightforward method of calculating the probability or the outcome of a coin flip.
The randomness of a single coin flip is absolute. When a coin is flipped over many times, the probability moves around the 0.5 mark, but not precisely that value. An interesting point of note is that if one throws the coin 1,000 times, the result will move much closer to 0.5.
This goes on to suggest that playing the game over a more extended period of time will eventually result in a 50/50, or 0.5 probability. Tossing a coin three times occurs in exactly 2 by 3 outcomes totaling 8 possibilities in all.
The official coinflip of the internet is also a good place where you can check how close the universe is towards a 50/50 situation. Our homepage states the total number of which we have seen Heads or Tails.
