Abstract strategy game

Source: Wikipedia, the free encyclopedia.
The abstract strategy game of Go

An abstract strategy game is a type of strategy game that has minimal or no narrative theme, an outcome determined only by player choice (with minimal or no randomness), and in which each player has perfect information about the game.[1] For example, Go is a pure abstract strategy game since it fulfills all three criteria; chess and related games are nearly so but feature a recognizable theme of ancient warfare; and Stratego is borderline since it is deterministic, loosely based on 19th-century Napoleonic warfare, and features concealed information.

Definition

The game Stratego

Combinatorial games have no randomizers such as dice, no simultaneous movement, nor hidden information. Some games that do have these elements are sometimes classified as abstract strategy games. (Games such as

Sequence, could be considered abstract strategy games, despite having a luck or bluffing element.) A smaller category of abstract strategy games manages to incorporate hidden information without using any random elements; the best known example is Stratego
.

Traditional abstract strategy games are often treated as a separate game category, hence the term 'abstract games' is often used for competitions that exclude them and can be thought of as referring to modern abstract strategy games. Two examples are the IAGO World Tour (2007–2010) and the Abstract Games World Championship held annually since 2008 as part of the Mind Sports Olympiad.[2]

Some abstract strategy games have multiple starting positions of which it is required that one be randomly determined. For a game to be one of skill, a starting position needs to be chosen by impartial means. Some games, such as

randomization of the starting position in chess in order to increase player dependence on thinking at the board.[3]

As J. Mark Thompson wrote in his article "Defining the Abstract", play is sometimes said to resemble a series of puzzles the players pose to each other:[4][5]

There is an intimate relationship between such games and puzzles: every board position presents the player with the puzzle, What is the best move?, which in theory could be solved by logic alone. A good abstract game can therefore be thought of as a "family" of potentially interesting logic puzzles, and the play consists of each player posing such a puzzle to the other. Good players are the ones who find the most difficult puzzles to present to their opponents.

Many abstract strategy games also happen to be "combinatorial"; i.e., there is no hidden information, no non-deterministic elements (such as shuffled cards or dice rolls), no simultaneous or hidden movement or setup, and (usually) two players or teams take a finite number of alternating turns.

Many games which are abstract in nature historically might have developed from thematic games, such as representation of military tactics.[6] In turn, it is common to see thematic version of such games; for example, chess is considered an abstract game, but many thematic versions, such as Star Wars-themed chess, exist.

History

Achilles and Ajax playing a board game.

Sanskrit: चतुरङ्ग), literally four divisions [of the military] – infantry, cavalry, elephants, and chariotry, represented by the pieces that would evolve into the modern pawn, knight, bishop, and rook, respectively. Chaturanga was played on an 8×8 uncheckered board, called ashtāpada.[11] Shogi was the earliest chess variant to allow captured pieces to be returned to the board by the capturing player.[12] This drop rule is speculated to have been invented in the 15th century and possibly connected to the practice of 15th century mercenaries switching loyalties when captured instead of being killed.[13]

A board resembling a

ancient Egyptian checkerboards, found with their pieces in burial chambers, and the game was played by Queen Hatasu.[15][16] Plato mentioned a game, πεττεία or Petteia [el], as being of Egyptian origin,[16] and Homer also mentions it.[16] The game was later imported into the Roman Empire under the name ludus latrunculorum.[17]

aristocratic Chinese scholars in antiquity. The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan[18][19] (c. 4th century BC).[20]

Comparison

Analysis of "pure" abstract strategy games is the subject of combinatorial game theory. Abstract strategy games with hidden information, bluffing, or simultaneous move elements are better served by Von Neumann–Morgenstern game theory, while those with a component of luck may require probability theory incorporated into either of the above.

As for the qualitative aspects, ranking abstract strategy games according to their interest, complexity, or strategy levels is a daunting task and subject to extreme subjectivity. In terms of measuring how finite a mathematical field each of the three top contenders represents, it is estimated that checkers has a

game-tree complexity
of 1040 possible games, whereas chess has approximately 10123. As for Go, the possible legal game positions range in the magnitude of 10170.

Champions

The Mind Sports Olympiad first held the Abstract Games World Championship in 2008 to try to find the best abstract strategy games all-rounder.[2] The MSO event saw a change in format in 2011[23] restricting the competition to players' five best events, and was renamed the Modern Abstract Games World Championship.
