Chess problem Wikipedia. A chess problem, also called a chess composition, is a puzzle set by somebody using chess pieces on a chess board, that presents the solver with a particular task to be achieved. For instance, a position might be given with the instruction that White is to move first, and checkmate Black in two moves against any possible defense. A person who creates such problems is known as a composer. There is a good deal of specialized jargon used in connection with chess problems see glossary of chess problems for a list. The term chess problem is not sharply defined there is no clear demarcation between chess compositions on the one hand and puzzles or tactical exercises on the other. In practice, however, the distinction is very clear. There are common characteristics shared by compositions in the problem section of chess magazines, in specialist chess problem magazines, and in collections of chess problems in book form. Not every chess problem has every one of these features, but most have several The position is composed that is, it has not been taken from an actual game, but has been invented for the specific purpose of providing a problem.

There is a specific stipulation, that is, a goal to be achieved for example, to checkmate Black within a specified number of moves. There is a theme or combination of themes that the problem has been composed to illustrate chess problems typically instantiate particular ideas. The problem exhibits economy in its construction no greater force is employed than that required to render the problem sound that is, to guarantee that the problems intended solution is indeed a solution and that it is the problems only solution.

Problems are experienced not only as puzzles but as objects of beauty. This is closely related to the fact that problems are organised to exhibit clear ideas in as economical a manner as possible. Problems can be contrasted with tactical puzzles often found in chess columns or magazines in which the task is to find the best move or sequence of moves usually leading to mate or gain of material from a given position. Such puzzles are often taken from actual games, or at least have positions which look as if they could have arisen during a game, and are used for instructional purposes. Most such puzzles fail to exhibit the above features. Types of problemseditGodfrey Heathcote. Hampstead and Highgate Express,1. PrizeWhite mates in two Solution 1. Rcc. 7 threatening 2. Nc. 31.

There are various different types of chess problems Directmates White to move first and checkmate Black within a specified number of moves against any defence. These are often referred to as mate in n, where n is the number of moves within which mate must be delivered. In composing and solving competitions, directmates are further broken down into three classes. Two movers White to move and checkmate Black in two moves against any defence. Three movers White to move and checkmate Black in no more than three moves against any defence. Moremovers White to move and checkmate Black in n moves against any defence, where n is some particular number greater than three. Helpmates Black to move first cooperates with White to get Blacks own king mated in a specified number of moves. Selfmates White moves first and forces Black in a specified number of moves to checkmate White. Helpselfmates White to move first cooperates with Black to get a position of selfmate in one move. Reflexmates a form of selfmate with the added stipulation that each side must give mate if it is able to do so. When this stipulation applies only to Black, it is a semi reflexmate. Seriesmovers one side makes a series of moves without reply to achieve a stipulated aim. Check may not be given except on the last move. A seriesmover may take various forms. Seriesmate a directmate with White playing a series of moves without reply to checkmate Black. Serieshelpmate a helpmate in which Black plays a series of moves without reply after which White plays one move to checkmate Black. Seriesselfmate a selfmate in which White plays a series of moves leading to a position in which Black is forced to give mate. Seriesreflexmate a reflexmate in which White plays a series of moves leading to a position in which Black can, and therefore must, give mate. Except for the directmates, the above are also considered forms of fairy chess insofar as they involve unorthodox rules. Download R4 Revolution For Ds Ndsl Nds. Studies an orthodox problem in which the stipulation is that White to play must win or draw. Almost all studies are endgame positions. Studies are composed chess problems, but because their stipulation is open ended the win or draw does not have to be achieved within any particular number of moves they are usually thought of as distinct from problems and as a form of composition that is closer to the puzzles of interest to over the board players. Indeed, composed studies have often extended our knowledge of endgame theory. But again, there is no clear dividing line between the two kinds of positions. In all the above types of problem, castling is assumed to be allowed unless it can be proved by retrograde analysis see below that the rook in question or king must have previously moved. En passant captures, on the other hand, are assumed not to be legal, unless it can be proved that the pawn in question must have moved two squares on the previous move. There are several other types of chess problem which do not fall into any of the above categories. Some of these are really coded mathematical problems, expressed using the geometry and pieces of the chessboard. A famous such problem is the knights tour, in which one is to determine the path of a knight that visits each square of the board exactly once. Another is the eight queens problem, in which eight queens are to be placed on the board so that none is attacking any of the others. Of far greater relation to standard chess problems, however, are the following, which have a rich history and have been revisited many times, with magazines, books and prizes dedicated to them Retrograde analysis problems such problems, often also called retros, typically present the solver with a diagram position and a question. In order to answer the question, the solver must work out the history of the position, that is, must work backwards from the given position to the previous move or moves that have been played. A problem employing retrograde analysis may, for example, present a position and ask questions like What was Whites last move, Has the bishop on c. Is the black knight promoted, Can White castle, etc. Some retrograde analysis may also have to be employed in more conventional problems directmates and so on to determine, for example, whether an en passant pawn capture or castling is possible.
