Bleicher Reading, U.K., Deventer, the Netherlands and Berlin, Germany ABSTRACT Van der Heijden’s ENDGAME STUDY DATABASE IV, HHDBIV, is the definitive collection of 76,132 chess studies. The zugzwang position or zug, one in which the side to move would prefer not to, is a frequent theme in the literature of chess studies. In this third data-mining of HHDBIV, we report on the occurrence of sub-7-man zugs there as discovered by the use of CQL and Nalimov endgame tables (EGTs). We also mine those Zugzwang Studies in which a zug more significantly appears in both its White-to-move (wtm) and Black-to-move (btm) forms. We provide some illustrative and extreme examples of zugzwangs in studies. -

The Instructor Tragicomedies in Pawn Endgames “Pawn endgames are rare birds in practice. Players avoid them, because they do not like them, because they do not understand them. It’s certainly no secret that pawn endings are ‘terra incognita’ - even for many masters, right up to the level of grandmasters and world champions.” N. Grigoriev Herewith, I offer proof that these words, spoken by a famous expert on pawn endings, are true. Without commentary, I give below the final moves of some actual games, and offer the readers the chance to comment on them, to uncover all the mistakes committed by both players. The endgames you will be dealing with here are not all that difficult; but still, the players on both sides have The provided you with plenty of opportunities for critical commentary. 1...Kf8 2.

Multilinear Algebra and Chess Endgames
Games of No Chance MSRI Publications Volume 29, 1996 Multilinear Algebra and Chess Endgames LEWIS STILLER Abstract. This article has three chief aims: (1) To show the wide utility of multilinear algebraic formalism for high-performance computing. (2) To describe an application of this formalism in the analysis of chess endgames, and results obtained thereby that would have been impossible to compute using earlier techniques, including a win requiring a record 243 moves. (3) To contribute to the study of the history of chess endgames, by focusing on the work of Friedrich Amelung (in particular his apparently lost analysis of certain six-piece endgames) and that of Theodor Molien, one of the founders of modern group representation theory and the first person to have systematically numerically analyzed a pawnless endgame. 1. Introduction Parallel and vector architectures can achieve high peak bandwidth, but it can be difficult for the programmer to design algorithms that exploit this bandwidth efficiently. Application performance can depend heavily on unique architecture features that complicate the design of portable code [Szymanski et al. 1994; Stone 1993]. The work reported here is part of a project to explore the extent to which the techniques of multilinear algebra can be used to simplify the design of high- performance parallel and vector algorithms [Johnson et al. 1991]. The approach is this: Define a set of fixed, structured matrices that encode architectural primitives • of the machine, in the sense that left-multiplication of a vector by this matrix is efficient on the target architecture. Formulate the application problem as a matrix multiplication. -

The world's largest endgame study database - edition 4 (HHdbIV) Introduction The fourth edition of the famous Harold van der Heijden endgame study database (HHdbIV) is available now. The new edition not only has more than eight thousand extra studies, but also the solutions of tens of thousands of studies have been corrected or updated. It is by far the most comprehensive collection of endgame studies available. Chess players can benefit from endgame studies by trying to solve them. This trains both one's calculation ability and tactical performance in the endgame. For the endgame study enthusiast, either admirer, cook hunter, composer or tourney judge HHdbIV is indispensable. Apart from the new studies the new version has many improvements over the previous edition. www.hhdbiv.nl What is an endgame study? An endgame study is a chess position presented as a puzzle with the stipulation White wins, or White draws, and has a unique solution. Although it looks like a game fragment, an endgame study has been composed. A good endgame study should have an entertaining solution with surprising moves or beautiful combinations that baffle chess players. It is also fun to try and solve endgame studies for both beginners and world class grandmasters as difficulty ranges from simple to very difficult. http://en.wikipedia.org/wiki/Endgame_study Chess Players "Studies are a very important part of the chess culture. I use a lot of studies for the training of imagination and calculations. The study database of Harold van der Heijden is the best source if you are looking for the less known positions". -

One of the First Things That Strikes the Endgame Study Enthusiast Is the Fact That There Have Been No Great British Composers
EG OCTOBER, 1965 One of the first things that strikes the endgame study enthusiast is the fact that there have been no great British composers. Certainly the British study has had its inspired moments, such as the famous study by Joseph which our first Tourney commemorates, but never has there been a plethora of fine composers, or even one who has really stood out from the rest. On the other hand, British problems have always been amongst the best, which to my mind indicates that chess composition is in our blood; furthermore, there is evidence that there is no lack of future problem talent at the present time. The reason for this lies, I am sure, in the lack of encouragement for composers and general interest among the chess public. It is to be hoped that the Chess Endgame Study Circle and its organ EG will provide the necessary stimulus for the budding composer by (a) keeping him in touch with recent developments (b) providing material for the improvement of his techniques (c) giving him the chance to display his best work prominently and (d) by holding regular meetings to stimulate discussion and allow for lectures by leading composers. More generally, the mere existence of E G should increase interest among chessplayers; by holding tourneys, by acting as a source book, by encouraging discussion, it should cause chess columnists and others to devote more time and space to studies. There is a place for the purely aesthetic in the average chess player's world, provided that it is intelligently presented.
