The line between the middlegame and the endgame is often not clear, and may occur gradually or with a quick [[exchange (chess)|exchange]] of pieces. The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns. In particular, [[pawn (chess)|pawns]] become more important as endgames often revolve around attempts to [[promotion (chess)|promote]] a pawn by advancing it to the eighth {{chessgloss|rank}}. The [[King (chess)|king]], which normally is kept safe during the game,<ref>{{Cite web |date=2015-07-16 |title=4 Basic Chess Opening Principles |url=https://rafaelleitao.com/4-basic-chess-opening-principles/ |access-date=2022-12-07 |website=Rafael Leitão |language=en-US}}</ref> becomes active in the endgame, as it can help escort pawns to promotion, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. Not all chess games reach an endgame; some of them end earlier.

All chess positions with up to seven pieces on the board have been [[Solved game|solved]] by [[Endgame tablebase|endgame tablebases]],<ref>{{Cite web |last=Fiekas |first=Niklas |title=KvK – Syzygy endgame tablebases |url=https://syzygy-tables.info/ |access-date=2022-12-07 |website=syzygy-tables.info |language=en}}</ref> so the outcome (win, loss, or draw) of best play by both sides in such positions is known, and [[Chess endgame literature|endgame textbooks]] teach this best play. However, most endgames are not solved, and even those which are can be difficult for humans to play, so textbooks teach useful [[Chess strategy|strategies]] and [[Chess tactic|tactics]] about them. The body of [[chess theory]] devoted to endgames is known as endgame theory. Compared to [[chess opening|opening]] theory, which changes frequently, giving way to middlegame positions that fall in and out of popularity, endgame theory is less subject to change.

Many [[endgame study|endgame studies]] have been composed; they consist of endgame positions which are solved by finding a win for White when there is no obvious way to win, or finding a [[draw (chess)|draw]] when White appears to lose. In some compositions, the starting position would be unlikely to occur in an actual game; but if the starting position is not artificial, the composition may be incorporated into endgame theory.

Endgames are usually classified based on the type of pieces that remain.
