Many readers will be familiar with tablebases, software that effectively plays perfect chess in certain endgame positions. If you’re new to the subject, though, refer to my introductory Adventures with endgame tablebases. As discussed in that blog series, the two most comprehensive tablebases currently are the Lomonosov and Syzygy, both of which cover all possible endgames with up to seven pieces. In the years since the releases of these databases, programmers have been building on the eight-piece version, which of course requires tremendous computer resources. One such developer, Marc Bourzutschky, has written a fascinating article-length update on the progress of his work, published on the Dutch endgame-study site, ARVES. Marc was the co-discoverer of the famous seven-piece position in which it takes White over 500 moves to force a win. Now he reveals which portions of the eight-piece tablebases have been completed and presents some of the most interesting positions found.
