  1. Selfmate

    chess notation A selfmate is a chess problem in which white, moving first, must force black to deliver checkmate within a specified number of moves against his will. Selfmates were once known as sui mates . Chess diagram tright Wolfgang Pauly , 1912 8 kl bl nl 7 pl pl pd pl 6 pl kd 5 pl pd 4 pl 3 2 bl 1 bd a b c d e f g h Selfmate in two The problem to the right is a relatively simple example. It is by Wolfgang Pauly ref http chess problems 2008 05 selfmates 1.html Pauly selfmate ref ref http libri pauly.htm W. Pauly ref from The Theory of Pawn Promotion , 1912 and is a selfmate in 2 White moves first, and compels Black to deliver checkmate on or before move two. Here, if White can leave Black with no option but to play Bxg2 , the problem is solved. White might try moving the bishop, but this is no good, as it will allow Black to play a non capturing bishop move himself, delaying the mate beyond move two moving the knight allows the king to move 1.e6 allows 1...exf6 and 2...f5 1.f7 or 1.fxe7 allows 1...Kxg7 1.g8Q or 1.g8R are no good after 1...Bxg2 2.Q Rxg2 1.g8N checkmates Black, which is entirely wrong 1.g8B is also no good, since after 1...exf6 2.exf6 Bxg2 the bishop can interpose with 3.Bd5. The only move by which White can force Black to deliver checkmate on or before move two is 1.c8N. There are two variations 1...exf6 2.exf6 Bxg2 is quite simple 1...e6 leads to the more subtle 2.g8B Bxg2 this only works because the bishop s path to d5 was blocked when Black played e6 . Note that only a promotion to a knight works on move one any other piece would be able to interpose after Bxg2. A derivative of the selfmate is the reflexmate , in which White compels Black to give mate with the added condition that if either player can give mate, they must when this condition applies only to Black, it is a semi reflexmate .

Checks cannot be given except on the last move of the series. There are various types of seriesmover Seriesmate a directmate with white playing a series of moves without reply to checkmate black the seriesmover analogue to the directmate . Serieshelpmate a helpmate in which black plays a series of moves without reply after which white plays one move to checkmate black the seriesmover analogue to the helpmate . Seriesselfmate a selfmate in which white plays a series of moves leading to a position in which black is forced to give mate the seriesmover analogue to the selfmate . Seriesreflexmate a reflexmate in which white plays a series of moves leading to a position in which black can, and therefore must, give mate. Further, white is obliged to mate whenever he can, therefore he has to avoid in his series of moves aposition in which he would have mating possibility the seriesmover analogue to the reflexmate . Thus a serieshelpmate in n moves consists of n legal unique moves by black all but possibly the last non checking moves followed by one move by white that mates black. To the right is a serieshelpmate in seventeen by Thomas Rayner Dawson published in Fairy Chess Review , 1947 . An effective way to solve long series help mates such as this is to envisage a position in which black could be checkmated, and then to work out how such a problem could be reached. Here, with just one knight, the only way to checkmate black is to have the black king in the corner and another black piece on a2, allowing Nb3 giving mate.

  1. The Problemist

    The Problemist is a chess problem magazine which has been in publication since January 1926. It originally had the subtitle Proceedings of the British Chess Problem Society but the words Proceedings of were dropped in January 1985. The foreword to the first issue, written by the editor T. R. Dawson , begins This little journal, bringing Happy New Year Greetings to every member of the B. C. P. S., will be to most of you a surprise calling for explanation. Its origin lies in the desire to have a medium in which the Society, as a collection of units and as a unity, may give expression to its thoughts and life. Following a suggestion from Mr F. F. L. Alexander, at the last annual general meeting, I obtained quotations for printing this periodical which enabled me to formulate a practical scheme for its continuance within the limits of our income. The scheme was unanimously adopted at a special meeting on Nov. 27th last, with Mr B. G. Laws in the chair and I accepted the meeting s invitation to edit these pages. Our title is a happy suggestion from Mr C. D. Locock. T. R. Dawson continued as editor of The Problemist until May 1931 when he resigned to devote more time to The Problemist Fairy Chess Supplement which he had begun in August 1930 in 1936 it was renamed The Fairy Chess Review . The post of editor of The Problemist was taken on by C. S. Kipping who held the position until his death in 1963. Subsequent editors have been John Ling, Colin Vaughan from March 1972, Paul Valois from May 1985 and John Rice from March 1999. All these general editors have been assisted by a team of section editors devoted to specific topics. The Problemist continues to be devoted essentially to orthodox chess problems, including regular columns on Endgame study endgames , selfmate s and helpmate s using the orthodox chess pieces. A fairy chess column was reintroduced by A. S. M. Dickins in march 1968. In January 1997, as a result of modern computer production methods, the page size of the ...   more details

  1. Motif (chess composition)

    unreferenced date August 2010 In chess composition , a motif is basic element of a move in the consideration why the piece moves and how it supports the fulfillment of a stipulation. Any move may and often does contain multiple motifs. Some composition school s put specific emphasis on motivation in chess problems, especially strategical school and Slovak school . A composition where a maximum number of a certain motif occurrences is shown is called a task chess composition task , even if the term task is more general. An example is the Babson task where all possible promotions are shown for both sides, leading to a reciprocal Allumwandlung . Classification of motifs Motifs may be classified according to various viewpoints. In the usual twomover s they might be positive those working towards the accomplishment of the stipulation attacking positive motifs of white moves weakening negative motifs of white moves negative those tending to hinder the accomplishment of the stipulation defensive negative motifs of black moves harmful positive motifs of black moves Similar classification is valid for all directmates, selfmate s, reflexmate s and other problems with antagonistic aims of sides, while for helpmate s and other help problems only positive negative level is applicable. Contents of motifs The basic orthodox motifs are preventing the move of other unit includes taking of a flight of the king allowing the move of other unit includes creating of a flight of the king guarding of some square or line unguarding of some square or line attacking of king checking In fairy chess some other motifs are possible.
