Effective Hand Strength (EHS) is a poker algorithm conceived by computer scientistsDarse Billings, Denis Papp, Jonathan Schaeffer and Duane Szafron that has been published for the first time in a research paper (1998). 'Opponent Modeling in Poker'(PDF). AAAI-98 Proceedings.
While not without flaws, poker winning percentages can reinforce essential Texas Hold’em concepts. Look at these hand charts and notice the average winning percentages. Any hand that has a score over 80 is a premium hand and anything over about 65. Poker Hands Ranked From Strongest to Weakest Royal Flush. The is the best possible hand you can get in standard five-card Poker is called a royal flush. Any five-card sequence in the same suit (e.g., 8, 9, 10, Jack and Queen of clubs. Jan 13, 2021 Other than the hands on that list, the only hands I would recommend a beginner play would be four-way connected hands, such as 8-9-T-J. Hands like these will typically give you a very strong hand on the flop, or a very weak hand, making it difficult to make large mistakes while playing them. Only a few hands have the strength to be viable to continue beyond the pre-flop action. Another important factor is your position. The later you get to act in each round, (i.e. The more people who.
It has since then been considered as a reference in the realm of poker artificial intelligence and has been the basis of further research such as:

Algorithm[edit]
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):
where:
- is the Effective Hand Strength
- is the current Hand Strength (i.e. not taking into account potential to improve or deteriorate, depending on upcoming table cards
- is the Negative POTential (i.e. the probability that our current hand, if the strongest, deteriorates and becomes a losing hand)
- is the Positive POTential (i.e. the probability that our current hand, if losing, improves and becomes the winning hand)
Poker Hand Strength Chart
Pseudocode[edit]
Hand Strength (HS) will enumerate all possible opponent hand cards and count the occurrences where our hand is strongest (+50% of the cases where we are tied):
In addition, EHS will consider the hand potential (i.e. its probabilities to improve or deteriorate):
Applicability[edit]
EHS is applicable to a wide variety of poker games such as Texas hold 'em poker, Omaha hold 'em poker, ...
Given the complexity of the algorithm, it can not be computed manually and has to be used in an Artificial Intelligence context.

| If you have any
questions or suggestions don't hesitate to send a mail -click here | On this site you can find all possible combinations of preflop hands that can occur in Texas Hold'em Poker. As a bonus you will also learn the nicknames of the different hands. The hands are ranked from #1 to #169, where #1 is the best. This ranking is applicable when the poker table is full ring (9-10 people). The ranking is based on computer calculation results with all the players staying to the river card. It is not applicable to any real play.
If the hand is named XXs then it means the hand is suited, if XXo then the hand is off suit.
