The term more-mover refers to a directmate problem in greater than three moves. More-movers, especially longer ones, are often easier to solve than three-movers, because the need to keep the black force under control means that White must proceed with short threats.

Many more-movers elaborate strategic themes more usually found in shorter problems. Two of the best known two-move ideas are the Grimshaw theme, which features mutual interference between two dissimilar line pieces, usually a rook and bishop, and the related Nowotny theme, where a piece plays to the intersection square of two line pieces, leading to the same effects as ordinary interferences.

Decoy of a black piece or pieces is a common feature in more-movers.

Another idea often exploited in more-movers is critical play, where a piece is enticed to play over a square to which a second piece then moves, interfering with the first piece.

Most longer more-movers fall into a category known as logical problems. The term derives from the fact that such problems have a single thematic line of play with a logical structure. White has a potential mating sequence, called a main-plan, which if attempted immediately will fail. He must first execute a foreplan to cause a change in the position which will allow the main-plan to operate.

Some problems feature a number of consecutive foreplans, or foreplans within foreplans.
