Challenge (competition): A challenge is a request made to the holder of a competitive title for a match between champion and challenger, the winner of which will acquire or retain the title.  In some cases the champion has the right to refuse a challenge; in others, this results in forfeiting the title.  The challenge system derives from duelling and its code of honour.  While many competitive sports use some form of tournament to determine champions, a challenge match is the normal way of deciding professional boxing titles and the World Chess Championship.  Some racket sports clubs have a reigning champion who may be challenged by any other club member; a ladder tournament extends the challenge concept to all players, not just the reigning champion.  At élite-level competition, there is usually some governing body which authorises and regulates challenges, such as FIDE in chess.  In some cases there is a challengers' tournament, the winner of which gains the right to play the challenge round against the reigning champion; in tennis this was the case at Wimbledon until 1922 and in the Davis Cup until 1972.  The FA Cup's official name remains the "Football Association Challenge Cup", although not since its second season in 1873 has the reigning champion receive a bye to the final.  The America's Cup is contested according to the terms of its 1887 deed of gift between yachts representing the champion yacht club and a challenging club.  Since 1970, the usual practice, by mutual consent, is for an initial formal "challenger of record" replaced by the actual challenger after a qualifying tournament.  However, in 1988 and 2010 there were court cases arising from non-consensual challenges.

Lineal championship: In combat sports where champions are decided by a challenge, the lineal championship of a weight class is a world championship title held initially by an undisputed champion and subsequently by a fighter who defeats the reigning champion in a match at that weight class.  In professional boxing, the lineal champion is informally called "the man who beat the man".  Champions recognized by sanctioning bodies such as the World Boxing Association (WBA) or World Boxing Council (WBC), or the Ultimate Fighting Championship (UFC) may vacate their title voluntarily, or be stripped of the title for breaching the sanctioning body's regulations or contracts.  There will thus be a breach of continuity in the list of sanctioned champions which the lineal championship is intended to prevent.  However, there is no single canonical list of lineal champions at any weight class, because there is no agreed upon method of determining the starting point for each lineage and conflicting opinions on what to do when the current champion retires or moves to a different weight class, although there is agreement that any stripping of a title be discounted.
