However, even so, some potentially useful ones would be missed due to space considerations. The engine can win this easily, and adding these tablebases are not going to improve performance. What would a 'useless' one be? Examples might be King+Queen+Queen versus King+Bishop+Pawn, and so forth. As a result, the Nalimov tablebase DVD set offered by ChessBase contains only a careful selection of the most useful six-piece combinations.

The complete six piece Nalimov tablebases take up about one full terabyte, or 1000 GB. More importantly though, this advantage spreads to the six-piece set also, where this size difference is much more evident. Of course, while freeing up 6 GB on your hard disk is a nice gain, it is hardly cataclysmic in today's age of hard drives with thousands of GB. The practical difference is that the full five-piece set of files takes up less than 1 GB, in other words they are over seven times smaller than the Nalimov tablebases. Developed by Ronald de Man, and published in 2013 for the first time, the Syzygy Bases consist of two sets of files, WDL files storing win/draw/loss information considering the fifty-move rule for access during search, and DTZ files with distance-to-zero information for access at the root. That is why the new Syzygy Bases are such an important step up. They represented an important evolution over the previous standard Edwards tablebases, since the five-piece set took up a mere 7.1 GB, which was about eight times smaller than the predecessor. The first five-man set came out in late 1998, and the six-man set was completed by 2005. There is an immediate and absolute result.įor over a decade now, the reference tablebase format has been the Nalimov set, created by Eugene Nalimov. A complete five-piece tablebase set means that everytime the position is reduced to five pieces (these always include kings), such as king+rook against king+rook+pawn, there are no calculations to be made. They represent the absolute indisputable truth of a position, that cannot be ignored. Tablebases have been a boon to chess players and researchers.
