Endgame Study
In the game of chess, an endgame study, or just study, is a type of chess problem that starts with a composed position—i.e. one that has been made up rather than played in an actual game—where the goal is to find the essentially unique way for one side (usually White) to win or draw, as stipulated, against any moves the other side plays. If the study does not end in the end of the game, then the game's eventual outcome should be obvious, and White can have a selection of various moves. There is no limit to the number of moves which are allowed to achieve the win; this distinguishes studies from the genre of direct mate problems (e.g. "mate in 2"). Such problems also differ qualitatively from the very common genre of tactical puzzles based around the middlegame, often based on an actual game, where a decisive tactic must be found. Composed studies Composed studies predate the modern form of chess. Shatranj studies exist in manuscripts from the 9th century, and the earliest trea ...

Chess
Chess is a board game for two players. It is an abstract strategy game that involves Perfect information, no hidden information and no elements of game of chance, chance. It is played on a square chessboard, board consisting of 64 squares arranged in an 8×8 grid. The players, referred to as White and Black in chess, "White" and "Black", each control sixteen Chess piece, pieces: one king (chess), king, one queen (chess), queen, two rook (chess), rooks, two bishop (chess), bishops, two knight (chess), knights, and eight pawn (chess), pawns, with each type of piece having a different pattern of movement. An enemy piece may be captured (removed from the board) by moving one's own piece onto the square it occupies. The object of the game is to "checkmate" (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw (chess), draw. The recorded history of chess goes back to at least the emergence of chaturanga—also thought to be an ancesto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Endgame
The endgame (or ending) is the final stage of a chess game which occurs after the middlegame. It begins when few pieces are left on the board. The line between the middlegame and the endgame is often not clear, and may occur gradually or with a quick exchange 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 attempts to promote a pawn by advancing it to the eighth . The king, which normally is kept safe during the game, becomes active in the endgame, as it can help escort pawns to promotion, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. Not all chess games reach an endgame; some of them end earlier. All chess positions with up to seven pieces on the board have been solved by endgame tablebases, so the outcome (win, loss, or draw) of best play by bot ...

Saavedra Position
The Saavedra position is one of the best-known chess endgame studies. It is named after the Spanish priest Fernando Saavedra (1849–1922), who lived in Glasgow during the late 19th century. Though not a strong player, he spotted a win involving a dramatic underpromotion in a position previously thought to have been a draw. The Saavedra position has inspired many chess composers. There are only four pieces, yet there are both tricks and counter-tricks, challenging a composer's imagination as to just what might be achievable with a full set of pieces. It is among a minority of positions where a king and a pawn can win against a king and a rook. Solution The position as it is usually given today, with White to move and win, is shown in the diagram. The solution is: :1. c7 Rd6+ 2. Kb5 (If 2.Kc5 then Rd1 threatening a skewer via 3...Rc1; if instead 2.Kb7? then Rd7 pins the pawn, allowing Black to capture it to assure a draw.) :2... Rd5+ Or 2...Rd2 3.c8=Q Rb2+ 4.Ka4 Ra2+ 5.Kb3 R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elo Ratings
The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess or esports. It is named after its creator Arpad Elo, a Hungarian-American chess master and physics professor. The Elo system was invented as an improved chess-rating system over the previously used Harkness system, but is also used as a rating system in association football (soccer), American football, baseball, basketball, pool, various board games and esports, and, more recently, large language models. The difference in the ratings between two players serves as a predictor of the outcome of a match. Two players with equal ratings who play against each other are expected to score an equal number of wins. A player whose rating is 100 points greater than their opponent's is expected to score 64%; if the difference is 200 points, then the expected score for the stronger player is 76%. A player's Elo rating is a number that may change depending on the outcome o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rook (chess)
The rook (; ♖, ♜) is a piece in the game of chess. It may move any number of squares horizontally or vertically without jumping, and it may an enemy piece on its path; it may participate in castling. Each player starts the game with two rooks, one in each corner on their side of the board. Formerly, the rook (from ) was alternatively called the ''tower'', ''marquess'', ''rector'', and ''comes'' (''count'' or ''earl''). The term "castle" is considered to be informal or old-fashioned. Placement and movement The white rooks start on the squares a1 and h1, while the black rooks start on a8 and h8. The rook moves horizontally or vertically, through any number of unoccupied squares. The rook cannot jump over pieces. The rook may capture an enemy piece by moving to the square on which the enemy piece stands, removing it from play. The rook also participates with the king in a special move called castling, wherein it is transferred to the square crossed by the king after th ...

King (chess)
The king (♔, ♚) is the most important chess piece, piece in the game of chess. It may move to any adjoining square; it may also perform, in tandem with the Rook (chess), rook, a special move called ''castling''. If a player's king is threatened with capture, it is said to be ''in Check (chess), check'', and the player must remove or evade the threat of immediately, such as by moving it away from the attacked square. If this cannot be done, the king is said to be in checkmate, resulting in a loss for that player. A player cannot make any move that places their own king in check. Despite this, the king can become a strong offensive piece in the Chess endgame, endgame or, rarely, the Chess middlegame, middlegame. In Algebraic notation (chess), algebraic notation, the king is abbreviated by the letter ''K'' among English speakers. The white king starts the game on e1; the black king starts on e8. Unlike all other pieces, each player can have only one king, and the kings are never ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexey Selezniev
Alexey (Alex) Sergeyevich Selezniev (, alternative transliterations: Selesniev, Selesniew, Selesnev, Selesnieff; pronounced "selezNYOFF"; 1888June 1967) was a Russian chess master and chess composer.

Sacrifice (chess)
In chess, a sacrifice is a move that gives up a piece with the objective of gaining tactical or positional compensation in other forms. A sacrifice could also be a deliberate exchange of a chess piece of higher value for an opponent's piece of lower value. Any chess piece except the king may be sacrificed. Because players usually try to hold on to their own pieces, offering a sacrifice can come as an unpleasant surprise to one's opponent, putting them off balance and causing them to waste precious time trying to calculate whether the sacrifice is sound or not, and whether to accept it. Sacrificing one's queen (the most valuable piece), or a string of pieces, adds to the surprise, and such games can be awarded . Types of sacrifice Real versus sham Rudolf Spielmann proposed a division between sham and real sacrifices: * In a ''real sacrifice'', the sacrificing player will often have to play on with less than their opponent for quite some time. * In a ''sham sacrifice'', ...
