Lopez and Nimzo-Indian Defence, among others; and, particularly with the King's Indian, translated his theoretical contributions into several spectacular victories with both colours (including the notable game below). Theoretically significant variations in the King's Indian and Ruy Lopez are named for him. His battles with Bobby Fischer in the King's Indian and Sicilian Defence (particularly the Najdorf Variation, a long-time Fischer specialty) often worked out in his favour. As a commentator, Gligorić was able to take advantage of his fluency in a number of languages and his training as a journalist, to produce lucid, interesting game annotations. He was a regular columnist for Chess Review and Chess Life magazines for many years, his "Game of the Month" column often amounting to a complete tutorial in the opening used in the feature game as well as a set of comprehensive game annotations. He wrote a number of chess books in several languages. One of the most notable was Fischer vs. Spassky: The Chess Match of the Century, a detailed account of their epic struggle for the world title in Reykjavík in 1972. He also contributed regularly to the Chess Informant semi-annual (more recently, thrice-yearly) compilation of the world's most important chess games. In 2019, FIDE established a fair play award named after Gligorić. The Fair Play Svetozar Gligoric Trophy is awarded annually by a three member commission in recognition of sportsmanship, integrity and the promotion ethical behavior within chess. Notable games One of Gligorić's most famous games was this win against the former world champion Tigran Petrosian at the great "Tournament of Peace" held in Zagreb in 1970. It displays Gligorić's virtuosity on the Black side of the King's Indian and his willingness to play for a sacrificial attack against one of history's greatest defenders. Zagreb 1970 was another Gligorić tournament success, as he tied for second (with Petrosian and others) behind Fischer, at the start of the latter's 1970–71 run of tournament and match victories.
