Correcting a published database error
FIDE's account of Karpov–Quinteros gives 35.Nf4 and a 1–0 result, exactly as preserved in the archive. That produces the contemporary final scores of Karpov 7½ and Quinteros 5½; the reversed result in 365Chess is an error. Larsen led the final table on 9½, Timman scored 9, and Ljubomir Ljubojević 8.
