The Chess Tempo endgame training allows you to play through endgame positions, trying to find the fastest way to mate. Often you do not have to play all the way to actual mate, as converting to a more easily won endgame (by capture or promotion) is usually enough, although if a quick mate is available after conversion, then you may be asked to play it. Promotion or capture may not always cause the problem to finish if it was deemed that the opponent still had threats that needed to be dealt with, for example when the opponent had very advanced pawns , the problem may not end until you have neutralized the promotion threat. All endgame problems start from positions that appeared in real games.
