Every page is also served as markdown at its URL plus .md. A mating net is a setup in which the enemy king is surrounded by attackers and its own pieces so tightly that checkmate cannot be avoided. A mating net is a setup in which the enemy king is surrounded by attackers and its own pieces so tightly that checkmate cannot be avoided, even if the final blow is a move or two away. The key idea is that the mate is forced before it is delivered. Every flight [square](https://georgelichess.com/glossary/square.md) is covered or blocked, and each defensive try leads to the same ending. You do not need the [checkmate](https://georgelichess.com/glossary/checkmate.md) on the board at once; you need to see that whatever the opponent does, the net stays closed. To build one, count the king's escape squares and ask which of your pieces watch each one. Bring in a queen or rook to cut off the squares, and let a [knight](https://georgelichess.com/glossary/knight.md) or [bishop](https://georgelichess.com/glossary/bishop.md) guard the square where the final piece will land. Often a forcing check starts the sequence, and the only reply drags a defender into the net. To avoid being caught, give your king breathing room early, keep a defender near it, and be wary of lines where all your pieces are on the far side of the board. Do not confuse a mating net with an ordinary attack. In a net the outcome is already forced, whatever the defender plays, while an attack can still be beaten off by accurate defense. The other trap is [opening](https://georgelichess.com/glossary/opening.md) the net with a check that hands the king an escape you missed, so list the flight squares before you commit. ## Example position White plays Qf6+. The only reply is Rg7, since the king has no square, and then Qxg7# wins, with the knight on e6 guarding g7. The queen and knight have closed the net around the h8 king. Position (FEN): `6rk/7p/4N3/8/8/8/5Q2/K7 w - - 0 1` It sits close to [Anastasia's mate](https://georgelichess.com/glossary/anastasias-mate.md). Anastasia's mate is a checkmate in which a knight and a rook trap a king on the edge, with the king's own pawn blocking its escape and the rook checking along the edge file. Also worth reading is [Arabian mate](https://georgelichess.com/glossary/arabian-mate.md). An Arabian mate is a corner checkmate where a rook gives the check from beside the king, and a knight, a jump away from the rook, guards it and covers the one flight square the rook leaves open. It sits close to [Blackburne's mate](https://georgelichess.com/glossary/blackburnes-mate.md). Blackburne's mate is a checkmate made with two bishops and a knight, where a bishop checks on h7 guarded by a knight on g5 while the other bishop on the long diagonal covers g7 and h8.
