 | | 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. |
 | | There is a good deal of specialized jargon used in chess problems; see chess problem terminology for a list. |
 | | 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). |
