🎯 Basic checkmates

You won a piece and reach an endgame with a crushing edge… but if you don't know how to finish, the point slips away. These three mates are pocket-sized: they're executed the same way every time, with the enemy king pushed to the edge.

The common idea: a lone king loses at the edge of the board. Your pieces take away ranks or files until they corner it, and there the mate falls.
