What game was Omar Sharif once ranked among the world's top 50?

Omar Sharif (April 1932 – 10 July 2015) was an Egyptian actor. He began his career in his native country in the 1950s, but is best known for his appearances in both British and American productions. His films included Lawrence of Arabia (1962), Doctor Zhivago (1965), and Funny Girl (1968). He was nominated for an Academy Award. He won three Golden Globe Awards and a César Award.

Sharif once ranked among the world's top 50 contract bridge players, and played in an exhibition match before the Shah of Iran. With Charles Goren, Sharif co-wrote a syndicated newspaper bridge column for the Chicago Tribune for several years, but mostly turned over the writing of the column to Tannah Hirsch. He was also both author and co-author of several books on bridge and licensed his name to a bridge video game; initially released in an MS-DOS version and Amiga version in 1992, Omar Sharif on Bridge is still sold in Windows and mobile platform versions. Computer Gaming World in 1992 described the game as "easy to get into, challenging to play and well-designed", and named it one of the year's best strategy games. In 1993 the magazine stated that "it does not play a very good game of bridge", however, and criticized it for inadequate documentation and forcing players to conform to its bidding style. The magazine recommended two other bridge games instead.
