Checkmate Pharmaceuticals
Checkmate (often shortened to mate) is any game position in chess and other chess-like games in which a player's king is in check (threatened with ) and there is no possible escape. Checkmating the opponent wins the game. In chess, the king is never actually captured—the player loses as soon as the player's king is checkmated. In formal games, it is usually considered good etiquette to resign an inevitably lost game before being checkmated. If a player is not in check but has no legal move, then it is ''stalemate'', and the game immediately ends in a draw. A checkmating move is recorded in algebraic notation using the hash symbol "#", for example: 34.Qg3#. Examples A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in Fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), or after many moves with as few as th ...

Chess Endgame
In chess and other similar games, the endgame (or end game or ending) is the stage of the game when few pieces are left on the board. The line between middlegame and endgame is often not clear, and may occur gradually or with the quick exchange of a few pairs of pieces. The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns. In particular, pawns become more important as endgames often revolve around attempting to promote a pawn by advancing it to the eighth . The king, which normally should stay hidden during the game should become active in the endgame, as it can help escort pawns to the promotion square, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. All chess positions with up to seven pieces on the board have been solved, that is, the outcome (win, loss, or draw) of best play by both sides is known, and textbooks and reference works teach th ...

Chess Rll45
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, ...

Medieval Times
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Roman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bare King
In chess and chess variants, a bare king (or lone king) is a game position where one player has only the king remaining (i.e. all the player's other pieces have been ). Effect on the game Historical In some old versions of chess, such as "baring chess" and shatranj, leaving the opponent with a bare king was one way of winning the game (see Checkmate#History). The relative weakness of the pieces in shatranj may have made this form of a win desirable. A possible exception to the bare king rule was if the king immediately after being bared was able to recapture, leaving the opponent with a bare king as well. This situation, called a "Medinese victory", was often considered a draw. Contemporary Under modern rules, a player with a bare king does not automatically lose and may continue playing. A bare king can never give check, however, and can therefore never deliver a checkmate or win the game. A bare king can in some situations play to a draw, such as by stalemate or if the oppon ...

Persian People
The Persians are an Iranian ethnic group who comprise over half of the population of Iran. They share a common cultural system and are native speakers of the Persian language as well as of the languages that are closely related to Persian. The ancient Persians were originally an ancient Iranian people who had migrated to the region of Persis (corresponding to the modern-day Iranian province of Fars) by the 9th century BCE. Together with their compatriot allies, they established and ruled some of the world's most powerful empires that are well-recognized for their massive cultural, political, and social influence, which covered much of the territory and population of the ancient world.. Throughout history, the Persian people have contributed greatly to art and science. Persian literature is one of the world's most prominent literary traditions. In contemporary terminology, people from Afghanistan, Tajikistan, and Uzbekistan who natively speak the Persian language are know ...

Metaphor
A metaphor is a figure of speech that, for rhetorical effect, directly refers to one thing by mentioning another. It may provide (or obscure) clarity or identify hidden similarities between two different ideas. Metaphors are often compared with other types of figurative language, such as antithesis, hyperbole, metonymy, and simile. One of the most commonly cited examples of a metaphor in English literature comes from the "All the world's a stage" monologue from '' As You Like It'': All the world's a stage, And all the men and women merely players; They have their exits and their entrances And one man in his time plays many parts, His Acts being seven ages. At first, the infant... :—William Shakespeare, '' As You Like It'', 2/7 This quotation expresses a metaphor because the world is not literally a stage, and most humans are not literally actors and actresses playing roles. By asserting that the world is a stage, Shakespeare uses points of comparison between the world an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Chess
The history of chess can be traced back nearly 1500 years to its earliest known predecessor, called chaturanga, in India; its prehistory is the subject of speculation. From India it spread to Persia. Following the Arab invasion and conquest of Persia, chess was taken up by the Muslim world and subsequently spread to Spain and the rest of Southern Europe. The game evolved roughly into its current form by about 1500 CE. "Romantic chess" was the predominant playing style from the late 18th century to the 1880s. Chess games of this period emphasized quick, tactical maneuvers rather than long-term strategic planning. The Romantic era of play was followed by the Scientific, Hypermodern, and New Dynamism eras. In the second half of the 19th century, modern chess tournament play began, and the first official World Chess Championship was held in 1886. The 20th century saw great leaps forward in chess theory and the establishment of the World Chess Federation. In 1997, an IBM super ...

Arab World
The Arab world ( ar, اَلْعَالَمُ الْعَرَبِيُّ '), formally the Arab homeland ( '), also known as the Arab nation ( '), the Arabsphere, or the Arab states, refers to a vast group of countries, mainly located in Western Asia and Northern Africa, that linguistically or culturally share an Arab identity. A majority of people in these countries are either ethnically Arab or are Arabized, speaking the Arabic language, which is used as the '' lingua franca'' throughout the Arab world. The Arab world is at its minimum defined as the 18 states where Arabic is natively spoken. At its maximum it consists of the 22 members of the Arab League, an international organization, which on top of the 18 states also includes the Comoros, Djibouti, Somalia and the partially recognized state of Palestine.
