Checkmate patterns
Boden's mate
Two bishops crisscross to mate a king stuck behind its own pieces.
What is the boden's mate?
Boden's mate is delivered by two bishops on crossing diagonals — most often against a king that castled queenside and is hemmed in by its own pieces. One bishop checks, the other covers the escape, and the king's own pawns and rook seal its fate.
Why the boden's mate matters
The criss-cross bishop picture is easy to miss precisely because bishops feel like quiet, long-range pieces. Learning Boden's mate rewires you to see two bishops as a mating net — which pays off in every opposite-side-castling attack.
How to use it to win
It almost always comes after a sacrifice that strips the queenside pawns or opens the diagonals. The tell is a king on c8 with a bishop already eyeing it and a second bishop that can reach the other diagonal with check.
A concrete example
A bishop on a6 checks the c8 king while a bishop on f4 covers b8 and d8 — mate, with the king smothered by its own rook and knight.
