New Riddle: Karpov-Hort 1979

Four world-class grandmasters met in a Dutch town for a double round-robin tournament. It was dominated by World Champion Anatoly Karpov, who went into the final round with a 1½-point lead and faced the second-placed GM Vlastimil Hort. Karpov won the game – but could Hort have prevented this happening? That’s an interesting riddle we want to solve. Can you help us?
