If king safety is a serious issue, a well-executed attack on the king can render other considerations, including material advantages, irrelevant. Material is another important consideration, Fine notes that—if all other things are equal—any material advantage will usually be decisive. According to Fine, a material advantage will usually not give a direct mating attack unless the advantage is very large a rook or more , rather it can be used as a means of gaining more material and a decisive endgame advantage. To gain mobility is to ensure that the pieces have a wide scope of action and targets to focus on. The concept is largely strategic in nature, and involves such concepts as space, pawn weaknesses since weak pawns can compel pieces to defensive duties, reducing their mobility , and securing outposts for the pieces. The strategy required for middlegame play varies considerably.
