Poker Effective Hand Strength (EHS) algorithm algorithm, it can not be computed manually and has to be used in an Artificial Intelligence context. Poker Effective Hand Strength (EHS) algorithm Effective Hand Strength (EHS) is a poker algorithm conceived by computer scientists Darse Billings, Denis Papp, Jonathan Schaeffer and Duane Szafron that has been published for the first time in a 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: The algorithm is a numerical approach to quantify the strength of a poker hand where its result expresses the strength
Lowball (poker) hands with pairs tie, kickers are used just as in high poker (but reversed): 3-3-6-4-2 defeats 3-3-6-5-A. This is called ace-to-five low because the lowest (and therefore best) possible hand is 5-4-3-2-A, called a "wheel". The next best possible hand is 6-4-3-2-A, followed by 6-5-3-2-A, 6-5-4-2-A, 6-5-4-3-A, 6-5-4-3-2, 7-4-3-2-A, 7-5-3-2-A, etc. When speaking, low hands are referred to by their highest-ranking card or cards. Any nine-high hand can be called "a nine", and is defeated by any "eight". Two cards are frequently used: the hand 8-6-5-4-2 can be called "an eight-six" and will defeat "an eight-seven" such as 8-7-5-4-A. Another
