Chess Endgames - ChessEndings

Endgames decide games, and almost nobody trains them. ChessEndings turns endgame theory into muscle memory: instead of watching lessons, you play each ending out against a built-in Stockfish tuned for maximum practical resistance. It never gives up the way raw engine lines do, so you have to find the real winning technique.

The basic checkmates, from the start
- King and queen mate, and the stalemate trap that ruins it
- King and rook mate with the box method
- Ladder mate with two rooks
- Mate with the two bishops
- Bishop and knight mate, the one everyone fumbles

The endgame families
- King and pawn: opposition, triangulation, the rule of the square, key squares
- Rook endings: the Lucena position, the Philidor position, the Vancura defense
- Bishop vs knight, opposite-colored bishops, queen vs rook
- Passed pawns, zugzwang, back-rank mate, the 50-move rule

Why it sticks
- Every mistake explained: when you slip, the coach shows you what went wrong and the idea behind the right move.
- No memorizing squares: revisit a position and the board is transformed, so you learn the technique, not the pattern.
- A defender that varies: in a lost position with several equally good defenses, it rotates between them and never picks a weaker one, so you train the whole ending and not a single line.
- Rated Gym: endless drills matched to your level, every position checked against the endgame tablebase.
- Journeys: guided paths from the basic mates up to the hard rook endings.
- Scan your own games: we find the won endgames you let slip, and the exact move.
- Play as a guest: no account needed to start.
