Example 1 shows the Syzygy results for this position with black to move. The top result is Kxf5, even though Qg5 is a better move because it immediately checkmates white. This best move is the 4th choice returned by the Syzygy tablebases. The program using the Nalimov tablebases returns the best move for the top choice.
How many pieces can you play in a syzygy table?
Syzygy tablebases. About. Syzygy tablebases allow perfect play with up to 7 pieces, both with and without the fifty-move drawing rule, i.e., they allow winning all won positions and bringing all drawn positions over the fifty-move line. The tables provide WDL and DTZ information.
What are the two sets of syzygy bases?
Syzygy Bases consist of two sets of files, WDL files (extension.rtbw) storing win/draw/loss information considering the fifty-move rule for access during search, and DTZ files (extension.rtbz) with distance-to-zero information for access at the root. WDL has full data for two sides but DTZ50 omitted data of one side to save space.
Which is smaller dtz50 or syzygy bases?
WDL has full data for two sides but DTZ50 omitted data of one side to save space. Each endgame has a pair of those types. Syzygy EGTB is significantly smaller than any DTM EGTB.
Which is the shortest way to mate DTZ or DTM?
DTZ optimal play is not always the shortest way to mate (DTM) and can even look unintuitive: For example sometimes pieces can be sacrificed to reset the fifty-move counter as soon as possible. However, unlike DTM it achieves the best possible result even with the fifty-move rule.
Which is the best way to mate in syzygy?
