A fork is an example of a {{chessgloss|double attack}}. The type of fork is named after the type of forking piece. For example, a fork by a [[Knight (chess)|knight]] is a ''knight fork''. The attacked pieces are ''forked''.<ref>{{Cite web|title=The Fork • lichess.org|url=https://lichess.org/practice/basic-tactics/the-fork/Qj281y1p/uAoBhXY8|access-date=2021-04-09|website=lichess.org}}</ref> If the [[King (chess)|king]] is one of the attacked pieces, the term ''absolute fork'' is sometimes used, while a fork not involving the enemy king is a ''relative fork''.<ref>{{Cite web|url=https://www.chess-game-strategies.com/|title=Chess Game Strategies - Next Chess Move|website=Chess Game Strategies}}</ref>

A fork of the king and queen, the highest {{chessgloss|material}}-gaining fork possible, is sometimes called a ''royal fork''. A fork of the enemy king, queen, and one (or both) [[Rook (chess)|rook]]s is sometimes called a ''grand fork''. A knight fork of the enemy king, queen, and possibly other pieces is sometimes called a ''family fork'' or ''family check''.<ref name="polgar">{{cite book |last=Polgar |first=S. |last2=Truong |first2=P. |title=A World Champion's Guide to Chess: Step-by-Step Instructions for Winning Chess the Polgar Way! |publisher=Russell Enterprises, Incorporated |year=2015 |isbn=978-1-941270-33-2 |url=https://books.google.com/books?id=MpFXDwAAQBAJ |access-date=2024-11-12 |page=cxix |quote=Here White can give a "family fork" by attacking three black pieces at once: king, queen, and rook, with 1.Nf4+.}}</ref><ref>{{cite book |last1=Hooper |first1=David |authorlink1=David Vincent Hooper |last2=Whyld |first2=Kenneth |authorlink2=Kenneth Whyld |title=[[The Oxford Companion to Chess]] |publisher=[[Oxford University Press]] |year=1996 |edition=2nd |origyear=First pub. 1992 |page=132 |contribution=family check |isbn=0-19-280049-3 }}</ref>
