Welcome to the Push or Fold Poker Calculator. This calculator is designed for players in full ring no limit holdem poker tournaments. Below 20 big blinds, depending on your hand, your position at the table, the ante percentage of the big blind and your number of big blinds, the calculator will tell you whether it is better to push or fold your hand to get a nash balance (provided no one has raised before you). This script is just a free tool based on Jennifear's push or fold tables

A History of Texas No Limit Hold'em

Texas No Limit Hold'em is the most widely played poker variant in the world. No-Limit Texas Hold'em (NLHE) is played live in casinos or on the Internet via gaming platforms. A game is played with two or more players and up to ten at a single table. In a traditional game with a total of 52 cards, each player involved in a game is dealt two cards of which only he or she is aware. Once the compulsory bets have been placed, five face-up cards are gradually revealed, first three (the flop), then another (the turn) and a final one (the river). Before the flop, and then at each felling, each player can bet or speak to see the rest of the table. Then, in order to win the pot that has been made up, one must either pass his opponent or show a better hand than his opponent, i.e. the best five-card combination between his private and open cards, from a single high to a royal flush.

push or fold Although the exact date of birth of Texas Hold'em and its origin are unknown, it is estimated that it was in the town of Robstown, Texas, in the early 1900s that the game was first played. It gradually replaced closed poker (a draw game) and was popularised in the casinos of the gambling iconic city, Las Vegas, from the 1960s onwards. The World Series Of Poker Championships at Binion's Casino in 1970 finally established Texas Hold'em as a flagship game and its fame has only grown ever since. Numerous books were published to explain the rules and understand the strategy of poker, right up to the more technological content of today such as video tutorials and computer software. It was in the 2000s that the Texas NLHE reached its apogee, notably thanks to Chris Moneymaker's victory in the $10,000 Main Event of the World Series Of Poker in 2003. Qualified via an internet tournament for only $18, the amateur won the title for $2.5 million, living the dream of all lovers of this game. From 839 entrants, participation in the event skyrocketed to nearly 2,500 the following year. Before continuing to grow exponentially since.

Texas No Limit Hold'em is a strategy game with incomplete information. In order to establish an optimal strategy in Texas NLHE, several factors must be taken into account, including the position at the table, the value of the starting hand, the bets placed, but also the mathematical aspect. It is the latter that interests us with push or fold tables. While poker as a whole cannot be analysed mathematically solely through game theory and its applications, they can nevertheless prove very useful in certain specific situations

John Nash and game theory

In the 1920s, a mathematical concept emerged through various scientific articles published in Europe and then brought to light by the American mathematician John Nash Forbes: game theory. This is a field of mathematics dealing with the reasoned or unreasoned choices of individuals in interactions. This theory applies to the social sciences but also to economics, politics, international relations etc.

Calculateur de push or fold After the essays of the German Ernst Zermelo and the French Emile Borel, the book Theory Of Games and Economic Behavior by John von Neumann and Oskar Morgenstern in 1944 lays the foundations of game theory and details the method of solving zero-sum games. Poker is a zero-sum game because the interest of one player is strictly opposed to the interest of the other player, one winner and one loser.

It was in the 1950s that the American mathematician and economist John Forbes Nash brought to light the notion of equilibrium, now known as the "Nash equilibrium", which determines an optimal strategy, with each player having no interest in deviating from it. This is a very specific situation that requires each player to predict the opponent's choice and maximize his or her winnings accordingly. If we apply this theory to poker, an optimal strategy is applied according to the opponent's strategies and this despite the absence of crucial information, the value of the opponent's cards. All aspects of the decision are taken into account in order to establish the best possible choice simultaneously and stick to it

Jennifear's charts and their use

Nash's balance applied to poker would therefore allow the player to never lose, regardless of the opponent's strategy. Thus, no regrets in case of defeat because we played in the best possible way, the one that ensures us a profit in the long run. Of course, poker, a game with incomplete information, with many decision factors, is not a form of mathematical resolution. But certain assumptions based on Nash's equilibrium can help to simplify the game and thus make it mathematically resolvable. The concrete application of this mathematical resolution are the Jennifear tables used in our calculator tool push or fold. Because if poker is simplified to push or fold, then decisions become calculable

Tool Operation

Before using our tool, there are several things you should know. In addition to the value of our cards, and whether or not they are of the same colour, carefully note your position (am I first to speak, am I in the middle of a position or in an armour battle?), the amount of ante versus armour, or your total number of large armour. Of course, the calculator only takes into account push (going all in) or fold (passing your hand immediately) situations in a full ring situation with 20 blinds or less, and not simple raises, with a view to a simplified and automatic game. Thanks to this mathematical resolution, your long-term winning expectation can only be positive
