Tablebases

Arasan can optionally make use of tablebases. Tablebases enable lookup of the best move for a given position. They are only effective in endgames in which there are a small number of pieces and/or pawns.

Arasan does not come with any tablebases installed. If you want to use tablebasese, you will need to download them or use a program to generate them. You will also need to edit the arasan.rc file (located in the directory where you installed Arasan) to point to the location of the tablebases.
