What this database actually do
Please reply

Endgame tables are special bases that are used by chess program engines when analyzing positions with a small number of pieces. When there are 6-7 or fewer pieces left on the board, if there are appropriate tables, the chess engine determines in seconds that the position is won, lost or drawn, and also calculates the shortest sequence of moves to achieve a win or a draw
