economy
Economy in chess composition has a number of aspects. Economy of force – there should be no unnecessary pieces in the position, and those that are should be used in the widest possible way. Economy of time – use the minimum number of moves needed to realize the idea. Economy of motivation
– keep all lines in the solution relevant to the theme. Economy of variety – avoid side variations unless they improve the quality or beauty of the composition. Economy of space – a very subjective criterion, which recommends that the game should be as distributed on the board as possible.
