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. -

EXERCISES SCHACHUBUNGSBUCH Шахматные комбинации Chess combinations Kombinationen Часть 1-2 разряд Part 1700-2000 Elo 3 Teil 1-2 Klasse Русский шахматный дом/Russian Chess House Москва, 2013 В первых двух книжках этой серии мы вооружили вас мощными приёмами для успешного ведения шахматной борьбы. В вашем арсенале появились двойной удар, связка, завлечение и отвлечение. Новый «Решебник» обогатит вас более изысканным тактическим оружием. Не всегда до короля можно добраться, используя грубую силу. Попробуйте обхитрить партнёра с помощью плаща и кинжала. Маскируйтесь, как разведчик, и ведите себя, как опытный дипломат. Попробуйте найти слабое место в лагере противника и в нужный момент уничтожьте защиту и нанесите тонкий кинжальный удар. Кстати, чужие фигуры могут стать союзниками. Умелыми манёврами привлеките фигуры противника к их королю, пускай они его заблокируют так, чтобы ему, бедному, было не вздохнуть, и в этот момент нанесите решающий удар. Неприятно, когда все фигуры вашего противника взаимодействуют между собой. Может, стоить вбить клин в их порядки – перекрыть их прочной шахматной дверью. А так ли страшна атака противника на ваши укрепления? Стоит ли уходить в глухую оборону? Всегда ищите контрудар. Тонкий промежуточный укол изменит ход борьбы. Не сгрудились ли ваши фигуры на небольшом пространстве, не мешают ли они друг другу добраться до короля противника? Решите, кому всё же идти на штурм королевской крепости, и освободите пространство фигуре для атаки. Короля всегда надо защищать в первую очередь. Используйте это обстоятельство и совершите открытое нападение на него и другие фигуры. И тогда жернова вашей «мельницы» перемелют всё вражеское войско. -

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 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". -

Detecting Fortresses in Chess
ELEKTROTEHNISKIˇ VESTNIK 79(1-2): 35–40, 2012 ENGLISH EDITION Detecting Fortresses in Chess Matej Guid, Ivan Bratko Artificial Intelligence Laboratory, Faculty of Computer and Information Science, University of Ljubljana, Trzaˇ skaˇ c. 25, Ljubljana, Slovenia Email: [email protected] Abstract. We introduce a computational method for semi-automatical detecting fortresses in the game of chess. It is based on computer heuristic search and can be easily used with any state-of-the-art chess program. We also demonstrate a method for avoiding fortresses and show how to find a break-through plan when one exists. Although the paper is not concerned with the question whether it is practical or not to implement the method within the state-of-the-art chess programs, the method can be useful, for example, in correspondence chess or in composing chess studies, where a human-computer interaction is of great importance, and the time available is significantly longer than in ordinary chess competitions. Keywords: fortress, chess, computer chess, game playing, heuristic search 1 INTRODUCTION In this paper, we will introduce a novel method for detecting fortresses. It is based on computer heuristic In chess, fortresses are usually regarded as positions search. We intend to demonstrate that due to lack when one side has a material advantage, however, the of changes in backed-up heuristic evaluations between defender’s position is an impregnable fortress and the successive depths that are otherwise expected in won win cannot be achieved when both sides play optimally. positions, fortresses can be detected effectively. We will The current state-of-the-art programs typically fail to also show how to avoid fortresses and possibly find a recognise fortresses and seem to claim a winning ad- break-through plan when one exists. -

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. -

The process of composing a chess endgame study using computer analysis tools, including endgame tablebases, is cited as an example of the partnership between an AI device and a human creator. I conclude with a suggestion to distinguish creative value from financial profit in evaluating IP issues in AI inventions, based on the fact that most chess puzzle composers follow IP conventions despite lacking any expectation of financial profit.
