A transposition is a change of route, most often in the opening: the moves come in an unusual order, yet the board ends up in a position normally associated with another order or even another opening. Positions do not remember how they were reached. After 1.Nf3 c5 2.e4 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3, every piece and pawn stands exactly where it would after the usual 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3, so the game that started with a [knight](https://georgelichess.com/glossary/knight.md) move is now an [Open Sicilian](https://georgelichess.com/glossary/open-sicilian.md), and everything known about that position applies. That simple fact turns [move orders](https://georgelichess.com/glossary/move-order.md) into a weapon. A player who wants a particular structure can approach it by an indirect road that hides the destination for a few moves, or that skips a line the opponent has prepared. Another common use is economy: a player can answer several different first moves with the same setup and steer all of them toward one family of positions. The price is that every road has its own side turnings. A flexible order that avoids one line may allow a different one, so before adopting it, list the replies it permits that your usual order did not. For study, organize your notes by position rather than by move sequence. When two orders lead to the same place, you only need to learn the position once. At the board, when the opponent plays an unexpected move, ask whether the resulting position matches something you know; quite often it does. Also worth reading is [Flank opening](https://georgelichess.com/glossary/flank-opening.md). A flank opening is a first move by White, such as 1.c4, 1.Nf3, 1.b3 or 1.f4, that leaves the d- and e-pawns at home and fights for the center with pieces and wing pawns instead. A neighboring idea is [Tabiya](https://georgelichess.com/glossary/tabiya.md). A tabiya is a standard, well known position that arises in a particular opening after a sequence of typical moves, and from which the main plans and ideas of both sides are understood. Whether "Transposition" suits your repertoire depends on the games you play.
