In 1956, Bobby Fischer, a 13-year-old boy and [[World Chess Championship 1972|future world champion]], won a famous game against the master player [[Donald Byrne]], establishing himself as a skilled player. Following an early queen sacrifice, Fischer coordinated his pieces to win a rook, two bishops, and a pawn for the sacrificed queen, thus gaining a winning material advantage.

In professional chess, when a game is clearly lost, it is customary for the losing player to resign rather than play until checkmate, both out of respect for one's opponent and also to avoid the tedium of forcing the opponent to play until checkmate, which the winning player may view as poor [[sportsmanship]]. However, Byrne is supposed to have conferred with some of his fellow players, deciding to play until checkmate for the same reason that most players resign ahead of time: as a sign of respect for Fischer's skill and also to allow the young Fischer the satisfaction of mate. The final result was a pure mate, with a black rook, bishop and knight trapping the white king against the edge of the board.<ref>{{cite book |author-link=Maurice Ashley |last=Ashley |first=Maurice |title=The Most Valuable Skills in Chess |year=2009 |publisher=Gambit |isbn=9781904600879 |pages=126–132}}</ref><ref>{{cite web |url=https://www.chessgames.com/perl/chessgame?gid=1008361 |title=Donald Byrne vs Robert James Fischer |website=[[Chessgames.com]]}}</ref>
