Wolfgang Uhlmann (1935-2020) was eight-time champion of East Germany between 1955 and 1985, and an early International Grandmaster, earning his title in 1959. He reached the Candidates Quarter-Final in 1971, but was eliminated by Bent Larsen.
Uhlmann was arguably the greatest expert on the French Defense in the history of chess. He replied to 1.e4 with 1…e6 almost exclusively. This is exceedingly courageous in high-level chess, when all of his opponents would have been expecting it! To this end, I still highly recommend Uhlmann’s 1995 book Winning with the French, as his insights are invaluable even if some of the theory has moved on.
Today we’ll look at Uhlmann’s sparkling victory with the Black pieces against Miguel Cuellar Gacharna (1916-1985) in the first round of the 1973 Leningrad Interzonal. Cuellar Gacharna was an International Master (1957) and nine-time champion of Colombia between 1941 and 1971. During his career he scored several victories over top players including Efim Geller, Viktor Korschnoj, Miguel Najdorf, Oscar Panno, and Samuel Reshevsky.
Black to play.
