The strongest tournament held between 1986 and 1987 was Bugojno 1986. This was a Class 12 tournament, including six of the top ten players in the world (from the May 1986 rating list). The next-strongest tournaments were Tilburg 1986 (Class 11) and Vienna (Open) 1986 (Class 9). The 5th International Bugojno Chess Tournament held in Yugoslavia in 1986 was the first category XVI event ever held. Eight top grandmasters were invited to participate in the double round robin. They were (in order of ELO): Anatoli Karpov (2700), Jan Timman (2645), Artur Yusupov (2645), Anthony Miles (2610), Lajos Portisch (2610), Boris Spassky (2610), Ljubomir Ljubojevic (2605), and Andrei Sokolov (2595). Karpov won once again, but Andrei Sokolov also made a terrific showing going undefeated and dealing Karpov his only loss in the tournament.
The sheet is slightly discolored and shows signs of wear else very good.
