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. -

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. -

see website www.hhdbiv.nl for ordering details. 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". -

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.

Some studies by Friedrich Amelung A name that frequently crops up in tlre literature of chess is that of F edrich Amelung (f842 1909). Heis pcrhaps besl known tbthis 8-man setting ofthe "en passttnt key" two-move ploblern task, published in Dlra Zeitung in 1897 and still uosurpassed after more thao a century: set white Kf5, Rh8, Pf6le5/h5 (5), Black Kh6, Ph7/95 (3), and White to play can mate in two by h5xg6 e.p- since Black's last movc musl have heer Pg7-g5 (not Pg('-95 because White would have been in check with Black to play, and not Kg7-h6 because Black would have been in chcck from While's Pt6 and there is nowhere the pawn could have come from to give that check). But in truth he was an all-rounder: player, co|nposer, analyst, journalist, cditor, and publisher. I am not aware of any mastcr tournaments in which he competed (lre lived in Riga and may have been inconveniently far from thc main ceotres of tournament activity), bu1 thc BIG99 database lhal carne with ChessBase 7.0 contained a couple 01 wild games he played,Lgainst Anderssen in Bcrlin in 1862 (one lost, one won), and thc Russian cncycfopaedia Sh.tkhnal) (1990) reports matchcs played in 1877 a-qainst Ashurin {won 4-3 with two draws) and Schillers (lost 6:2 11ith four draws). -

The Best of British To round off B'SN, let me present again some of the finest British studies, or studies with a major British componcnt, that have appeared over the years. I have normally restricted myself to one study by each composer (there are three exceptions), and I have selected the study which seems to me to be his most striking and not necessarily that which he himself regArded as his best, Be it also noted that many fine composers do not appear here at all; I could not accommodate everyone within twelve pages. 1a - after 3...Kh6 4 Ne2 One exception is of course Mike Bent, who canrlol be properly represented by one study afone. His 1 appeared in Schakend Nederland in 1976- Black's promotion cannot be prevented, but I Kfl limits him io 1...h1Q, and 2 B|3 forces 2...Qh2. Now comes 3 Be4+ and 4 Ne2 (see 1a), and what can Black do? His queen cannot move al all, his king c.mnot cross the line c1-c3-d3-d4-f4-13-g3, and White's can oscillate indefinitely between el andfl. In Mike's words, White's fortress holds a dungeon. ''f o1.o' T//:H, ru ffi 2b-after8Nf6 Mike always gave thanks to the unknown genius who invefted the kdght's move.
