In Zia Mahmood's book, "Bridge, My Way" (1992), Zia offered a £1 million bet that no four-person team of his choosing would be beaten by a computer. A few years later the bridge program "GIB" (which can stand for either "Ginsberg’s Intelligent Bridgeplayer" or "Goren In a Box"), brainchild of American computer scientist Matthew Ginsberg, proved capable of expert declarer plays like winkle squeezes in play tests. In 1996, Zia withdrew his bet. Two years later, "GIB" became the world champion in computer bridge, and also had a 12th place score (11210) in declarer play compared to 34 of the top humans in the 1998 Par Contest (including Zia Mahmood). However, such a par contest measures technical bridge analysis skills only, and in 1999 Zia beat various computer programs, including "GIB", in an individual round robin match.
