Chess problem - Encyclopedia, History, Geography and Biography |
 | | A chess problem, formally called a chess composition, is a puzzle set by somebody using chess pieces on a chess board, presenting the solver with a particular task to be achieved. |
 | | Problems can be contrasted with tactical puzzles often found in chess columns or magazines in which the task is to find the best move or sequence of moves (usually leading to mate or gain of material) from a given position. |
 | | In both formal and informal tourneys, entries will normally be limited to a particular genre of problem (for example, mate in twos, moremovers, helpmates) and may or may not have additional restrictions (for example, problems in patrol chess, problems showing the Lacny theme, problems using fewer than nine units). |
