Every page is also served as markdown at its URL plus .md. A double attack is one move that creates two threats at once, whether they come from a single piece or from two, and whether they aim at pieces or at checkmate. A double attack is one move that creates two threats at once, whether they come from a single piece or from two, and whether they aim at pieces or at checkmate. Think of it as the umbrella term for every move that does two jobs. A fork is the version where one piece hits two targets. Others include a [discovered attack](https://georgelichess.com/glossary/discovered-attack.md), where the unmasked piece and the mover each threaten something, and a move that attacks a piece while preparing checkmate. The second target does not have to be material. A threat of mate is the heaviest threat there is, so [pairing](https://georgelichess.com/glossary/pairing.md) it with an attack on a [loose piece](https://georgelichess.com/glossary/loose-piece.md) makes a strong double attack: the opponent must stop the mate and the piece falls anyway. Back-rank threats are the commonest partner, because a king with no luft has to give up something. To find these moves, review your [candidates](https://georgelichess.com/glossary/candidates-tournament.md) not by what they capture but by how many different things they threaten. Count captures, checks and mating ideas together. A [rook lift](https://georgelichess.com/glossary/rook-lift.md) to the seventh rank, for example, tends to hit loose pieces along the rank while eyeing the back rank. To defend, make a habit of asking what your opponent's [best move](https://georgelichess.com/glossary/best-move.md) would threaten after it is played, and see whether one reply covers all of it. Missing luft, loose pieces and pieces defended only by the king are what make a double attack work. In the diagram White plays Re7. The rook attacks the knight on a7 and threatens Re8# on the back rank. Black can stop the mate with a pawn move, but then Rxa7 wins the knight. ## Example position White to move plays Re7. The rook attacks the knight on a7 and threatens Re8#, so Black either allows mate or loses the knight to Rxa7. Position (FEN): `6k1/n4ppp/8/8/8/8/5PPP/4R1K1 w - - 0 1` It sits close to [Desperado piece](https://georgelichess.com/glossary/desperado-piece.md). A desperado is a doomed piece that cashes in before it dies: it captures or gives check, taking the most it can from the position instead of being lost for nothing. Also worth reading is [Fork](https://georgelichess.com/glossary/fork.md). A fork is a move that leaves one of your pieces threatening two enemy pieces together. A neighboring idea is [Pawn fork](https://georgelichess.com/glossary/pawn-fork.md). A pawn fork is a pawn move that attacks two enemy pieces at once, one on each of the two diagonal squares ahead of the pawn, so only one of them can escape.
