Endgame tables (Table Bases).

All the positions with 5 pieces on the board and some of the most important with six, are organized into a group of files called the "Table Bases" (TB). With each position recorded, by perfect play, one can win, draw or lose irremediably. Besides, it's also recorded the exact number of moves required to arrive at the end of the main variation, that is to say, a variation in which both sides always do the best possible move. The Table Bases can be obtained freely on Internet or bought in CD or DVD (taking several Gbytes of storage)
