How do I turn the endgame tablebase on?
For most Chess engines, you only need to add a path to the tablebase directory in the configuration files of the relevant Chess engine. For example, you add only add the line tbpath=c:\chesseng\tb into the Crafty.rc file if you want Crafty to use tablebases. Just change the path to where-ever your tablebases are. Mine is at c:\chesseng\tb.
