<!--NOT BOLDED, PER [[WP:MOS]]-->This article covers [[computer software]] designed to solve, or assist people in creating or solving, [[chess problem]]s – [[puzzle]]s in which pieces are laid out as in a game of [[chess]], and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the [[Chess composer|problemist]] to find a solution to the posed situation, within the [[rules of chess]], rather than to play games of chess from the beginning against an opponent.

This is usually distinct from actually [[Computer chess|playing and analyzing games of chess]]. Many chess playing programs also have provision for solving some kinds of problem such as [[checkmate]] in a certain number of moves ([[Chess problem#Types of problem|directmates]]), and some also have support for [[helpmate]]s and [[selfmate]]s.
