Chess Endgame News

Three topics are discussed. First, an issue in the epistemology of computer simulation - that of the chess endgame 'becoming' what computer-generated data says it is. Secondly, the endgames of the longest known games are discussed, and the concept of a Bionic Game is defined. Lastly, the set of record-depth positions published by Bourzutschky and Konoval are evaluated by the new MVL tables in Moscow - alongside the deepest known mate of 549 moves.

This note defines what it means by the 'chess endgame' and looks at the frequency of sub-n-man and 'FinalGen' positions in games and studies and in the FIDE 2013 World Cup. It includes the exposition of the DTM-minimaxing line from one of the three DTM-deepest known (KQPKRBN) positions. It refines the definitions of 'longest game' and 'bionic game'. The games of the FIDE 2013 World Cup and the longest known decisive game are available here.

Are investors guided by the news disclosed by companies or by journalists?

Most previous studies demonstrating the influential role of the textual information released by the media on stock market performance have concentrated on earnings-related disclosures. By contrast, this paper focuses on disposal announcements, so that the impacts of listed companies’ announcements and journalists’ stories can be compared concerning the same events. Consistent with previous findings, negative words, rather than those expressing other types of sentiment, statistically significantly affect adjusted returns and detrended trading volumes. However, extending previous studies, the results of this paper indicate that shareholders’ decisions are mainly guided by the negative sentiment in listed companies’ announcements rather than that in journalists’ stories. Furthermore, this effect is restricted to the announcement day. The average market reaction–measured by adjusted returns–is inversely related only when the announcements are ignored by the media, but the dispersion of market reaction–measured by detrended trading volume–is positively affected only when announcements are followed up by journalists.

This note includes some endgame reflections on the last World Chess Championship, an update on the search for the longest decisive games between computers, and a brief mention of the sets of endgame table (EGT) statistics recently received from Yakov Konoval (2013) and from Victor Zakharov (2013) for the Lomonosov team.

This paper notes FIDE's 75-move rule (9.6b) and suggests some implications. It reviews two endgame-table initiatives associated with the 50-move rule. One is Huntington's mainly sub-6-man multi-valued DTM50 EGTs implemented in HASKELL. The other is Ronald de Man's WDL' and DTZ50' EGTs which introduce a 5-way evaluation of positions, and ascribe a depth to decisive positions which are not 50-move-rule wins or losses. There is also some first detail about the Lomonosov '7-man DTM EGT' team, and comments on reactions to 'Haworth's Law'.

The spaces of the Wednesday Play (BBC TV 1964–1970): production, technology and style

The BBC television drama anthology The Wednesday Play, broadcast from 1964-70 on the BBC1 channel, was high-profile and often controversial in its time and has since been central to accounts of British television’s ‘golden age’. This article demonstrates that production technologies and methods were more diverse at that time than is now acknowledged, and that The Wednesday Play dramas drew both approving but also very critical responses from contemporary viewers and professional reviewers. This article analyses the ways that the physical spaces of production for different dramas in the series, and the different technologies of shooting and recording that were adopted in these production spaces, are associated with but do not determine aesthetic style. The adoption of single-camera location filming rather than the established production method of multi-camera studio videotaping in some of the dramas in the series has been important to The Wednesday Play’s significance, but each production method was used in different ways. The dramas drew their dramatic forms and aesthetic emphases from both theatre and cinema, as well as connecting with debates about the nature of drama for television. Institutional and regulatory frameworks such as control over staff working away from base, budgetary considerations and union agreements also impacted on decisions about how programmes were made. The article makes use of records from the BBC Written Archives Centre, as well as published scholarship. By placing The Wednesday Play in a range of overlapping historical contexts, its identity can be understood as transitional, differentiated and contested.

The DTZ metric indicates the minimaxed 'Depth To Zeroing of the ply-count' for decisive positions. Ronald de Man's DTZ50' metric is a variant of the DTZ metric as moderated by the FIDE 50-move draw-claim rule. DTZ50'-depths are given to '50-move-rule draws' as well as to unconditionally decisive positions. This note defines a two-dimensional taxonomy of positions implicitly defined by DTZ50'. 'Decisive' positions may have values of (wins/losses) v =1/-1 or v = 2/-2. A position's depth in the new DTZ50' metric may be greater than, equal to or less than its DTZ depth. The six parts of the taxonomy are examined in detail, and illustrated by some 40 positions and 16 lines. Positions, lines and the annotation of these lines are supplied in the ancillary data files.

This note investigates the recently revived proposal that the stalemated side should lose, and comments further on the information provided by the FRITZ14 interface to Ronald de Man’s DTZ50' EGTs. The history of stalemate is convoluted, and there is an argument for computing chess endgame tables to revised rules to examine the impact of any change. The FRITZ14 interface to the DTZ50' EGTs exhibits residual 'one-out' and end-of-phase errors. Example positions are provided to illustrate the stalemate and the DTZ50' issues described.

Newborn and Hyatt recently tested the chess-engine CRAFTY on two test sets of 16 positions each. The performance of an engine making greater use of endgame tables (EGTs) is compared with that of CRAFTY. Reference is made to three other articles in which composed positions have been used to test a variety of chess engines. Supporting data here comprises two pgn files, an annotated-pgn file and the original data worksheets used.

'All in one stroke': Grimms' fairy tales and the TV-production of a new Germany

The article looks at the most recent TV adaptations of the Grimms’ fairy tales by public broadcasting. Realized and marketed as a season which started in 2008,the thirty-four currently existing individual films constitute a significant national project that presents highly appealing notions of the German past to an audience divided over national conflict and demands of globalization. With children and adolescents at the centre, the films offer the young as a generation of moral superiority that facilitates social harmony and moral consensus. This post-unification utopia is beautifully realized on screen but rests on very conservative assumptions about gender, social driving forces, and political order.

Authenticity and performance of class in British factual TV series

The chapter characterises British ‘Reality TV’ as a hybrid of factual and fictional television genres, as signaled by the more accurate genre designation ‘structured reality’ television. From the 1990s onwards, in order to develop programmes that are attractive to audiences and inexpensive to produce, programme makers have focused on hybrids of dramatic and documentary modes. This chapter argues that many recent Reality TV programmes privilege soap opera’s emphasis on character, storyline and performance. This affects the ways that class authenticity is understood, undermining factual programmes’ usual claim to legitimacy based on reference to a pre-existing reality, and transforming hierarchies that separate highly-valued from low-valued types of programme.

An enhanced content selection mechanism for personalization of video news programmes

In this paper, we propose a content selection framework that improves the users` experience when they are enriching or authoring pieces of news. This framework combines a variety of techniques to retrieve semantically related videos, based on a set of criteria which are specified automatically depending on the media`s constraints. The combination of different content selection mechanisms can improve the quality of the retrieved scenes, because each technique`s limitations are minimized by other techniques` strengths. We present an evaluation based on a number of experiments, which show that the retrieved results are better when all criteria are used at time.
