Karpov-Jussupow, Soviet Championship, Moscow 1983
As explained in the video below, strong prophylactic play is one of the most difficult things in the game of chess. One must constantly search and find the best moves for both sides. Anatoly Karpov was a great master of understanding opponent's intentions and finding subtle ways to prevent them. The present game is a formidable strategical battle, in which Karpov outplays Artur Jussupow - a fine positional player himself - by constantly using short tactics to reach his strategic goals. Black's desperate attempt to complicate matters by launching an attack against White's king is cold-bloodedly rejected by Karpov, who plays precisely until the very end to take home the full point.
