My first impression of Shirov -- Gurevich, Munich 1993 (
Chess Informant 57/287) was that the game requires more than the usual five minutes observing patterns. Gurevich sacrificed material to open the board before Shirov castled. Later, Shirov struck back and eventually prevailed. According to Shirov's annotations for
Informant, Gurevich strayed from the best course from this position.
