Negotiations for a training match between Judit Polgar and Boris Spassky began in November 1992.(1)

On November 18, Judit was informed that the match would start on January 31st, 1993. 12 games were to be played and split between Budapest, Hungary, and Sveti Stefan, Montenegro. The prize fund was to be $200,000 and the Fischer clock was to be used. The time control was 1 hour and 50 min, plus a 1 min increment per move, for the first 40 moves. Small changes were made later, with the number of games was reduced to 10, all of them to be played in Budapest.(1)

Only on January 20 had it become certain that the match would indeed take place. Judit immediately asked Lev Polugaevsky to become her second. He accepted her proposal. Spassky's seconds were Aleksander Nikitin and Yuri Balashov. During the opening ceremony at the Vakert Casino, Judit drew the number 13, so she got Black in the first game. The match took place in the ballroom of the Intercontinental Hotel, which hosted about 1000 visitors per day. A change was made for game 10, which took place in the Beke Hotel. The winner would receive $120,000 and the loser $80,000.(1)(2)

The match was being staged by Jezdimir Vasiljevic, who had financed Fischer - Spassky (1992), and was organized by Janos Kubat.(4)
