Tablebases are essentially databases of endgame positions that have been exhaustively analysed so that their outcomes (win/loss/draw) with best play by both sides are known with certainty.
Which is the best engine for endgame analysis?
Whether it be Deep Fritz 14, or Houdini 4 (and many others), these engines can not only use these tablebases but refer to them in their analysis and as a result play much better in endgames. Tablebases are a form of oracle in that their answers are always 100% correct
How are precalculated endgame tables generated in chess?
precalculated endgame tables generated by an exhaustive retrograde analysis. During its game play and/or search, recognizing a specific material composition, a chess program can probe, or in principle compute these tables to determine the outcome of positions definitively and act as an oracle providing the optimal moves.
Who is the author of Syzygy endgame tablebases?

Where can I find endgame tablebases for chess?
The Chess Endgame Study Database, which enables searches based on the exact material used, brings up five studies with matching pieces. An examination of these varied endgames reinforces my view that the setting above is of publishable quality.

3/21/2018 – The new Endgame Turbo 5 represents the ultimate tablebase collection available and can be used simply by sticking it into a USB port on your computer. It contains the full 3-4-5 and 6-piece tablebases on a pen drive so that neither hard disk space or SSD drive are required to take advantage of them.
Can a tablebase engine solve a chess study?
While engines like Stockfish are strong enough to solve most studies, they do so without necessarily providing certainty to the accuracy of the intended play. Tablebases can do these verification tasks perfectly and instantaneously, within the 7-piece limit.

What can you do with a Syzygy tablebase?
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. Forcing captures or pawn moves while keeping a win in hand ensures that progress is being made.
How many chess positions have been solved by tablebase?
By 2005, all chess positions with up to six pieces (including the two kings) had been solved. By August 2012, tablebases had solved chess for every position with up to seven pieces (the positions with a lone king versus a king and five pieces were omitted because they were considered to be “rather obvious”).
How are the records of an endgame organized?
All records of an endgame are simply organized as two arrays (one array for one side/color). In other words, each item in those arrays is an integer and its index on an array is mapped to a unique position. For a given chess position, we will calculate its index then access its data record/integer via that index without searching.
