Paper on 6-piece zugzwangs

Post by BB+ » Tue Jun 22, 2010 6:05 am

For those of you with SpringerLink access: http://www.springerlink.com/content/2257352422272wv7/

6-Man Chess and Zugzwangs
Eiko Bleicher and Guy Haworth
Abstract:
With 6-man Chess essentially solved, the available 6-man Endgame Tables (EGTs) have been scanned for zugzwang positions where, unusually, having the move is a disadvantage. Review statistics together with some highlights and positions are provided here: the complete information is available on the ICGA website. An outcome of the review is the observation that the definition of zugzwang should be revisited, if only because the presence of en passant capture moves gives rise to three new, asymmetric types of zugzwang.

Deriving Concepts and Strategies from Chess Tablebases
Matej Guid, Martin Možina, Aleksander Sadikov and Ivan Bratko
Abstract:
Complete tablebases, indicating best moves for every position, exist for chess endgames. There is no doubt that tablebases contain a wealth of knowledge, however, mining for this knowledge, manually or automatically, proved as extremely difficult. Recently, we developed an approach that combines specialized minimax search with the argument-based machine learning (ABML) paradigm. In this paper, we put this approach to test in an attempt to elicit human-understandable knowledge from tablebases. Specifically, we semi-automatically synthesize knowledge from the KBNK tablebase for teaching the difficult king, bishop, and knight versus the lone king endgame.
