Tablebase Endgames in Chess
Tablebase endgames are chess positions with a limited number of pieces that have been solved exhaustively by computer. Most practical tablebases cover positions with seven or fewer pieces, showing whether each position is a win, draw, or loss with perfect play.
When the board reaches seven pieces or fewer, identify the exact position and consult a tablebase to verify the result and best move. Pay special attention to opposition, pawn races, stalemate ideas, and the fifty-move counter, since one tempo can change the tablebase outcome.
