Mating net — what it means in chess
A web of threats from which the enemy king cannot escape.
A web of threats from which the enemy king cannot escape.
A mating net is the cage before the checkmate: a coordinated arrangement of pieces that strips the enemy king of flight squares, one move at a time, until the final check has no answer. The net is why strong players talk about mating the king rather than checking it — checks that let the king run achieve nothing, while quiet moves that close escape squares achieve everything.
The purest teaching example is the two-piece ladder, sometimes called the lawnmower: queen and rook take alternate ranks, and every move shrinks the box.

Qh8 " caption="The lawnmower: queen and rook herd the king rank by rank until the net closes." notes="White to move. Queen and rook against a bare king in the middle of the board. Qh4+ — the queen seals the fourth rank. The king must step to the fifth. Kd5 — upward, into the shrinking box. Ra5+ — now the rook seals the fifth. Each piece holds a rank while the other leapfrogs. Kd6 — the box shrinks again. Qh6+ — the queen takes the sixth. Kd7 — one rank left. Ra7+ — the rook takes the seventh. Kd8 — the edge of the board: the far wall of the net. Qh8 — the queen arrives on the eighth. Rook holds the seventh, queen holds the eighth, and there is nowhere left."]]
Every basic checkmate is a mating net in miniature, and the back-rank mate is a net the defender built against themselves. When you attack, count escape squares, not checks.
