Leningrad Lip

I had intended this week to write about the surprise surge by Mamedyarov which overturned all expectations in the elite Gashimov Memorial. Instead, the death of Viktor Korchnoi, known variously as Viktor the Terrible or the Leningrad Lip, represents a force majeure priority. An outspoken defector and three-times world champion contender, Korchnoi was one of the dominating figures of 20th-century chess.
 
This week, a win against the legendary Bobby Fischer and a puzzle position against his arch foe Anatoly Karpov. Comments based on those by Cyrus Lakdawala in Korchnoi: Move by Move (Everyman Chess).
