Game of the Week #716: Udovcic vs Korchnoi

3/26/2026 – Last week we honored Jan Timman, who passed away a few weeks ago, by studying his brilliant attacking game against Anatoli Karpov. This week at Chessbase we dedicate our shows to the legendary Viktor Kortchnoi, who would have turned 95. Hans Ree wrote that Viktor told him back in the day that he choose Kortchnoi as the right spelling of his name, since it combines something from several languages. Our Game of the Week is his amazing attacking game against Mijo Udovcic. Merijn's show is available on-demand with a ChessBase Premium Account. You can register a Premium account here.

Among the standout games was the pairing of Divya Deshmukh & Christina Jordan against Bao Anh Angelina Nguyen Doan & Benjamin Gledura. The game seemed firmly in White’s hands before the momentum shifted dramatically, turning into a commanding position for Black.

At move 88, with queen and b-pawn against queen, Golubenko's opponent held for 37 moves, until he missed an only move, and it was theoretically a mate in 47.

ChessBase author Nico Zwirs takes a look at similar, but reversed structures. His 60 Minutes course is aptly titled “Reversed Sicilian Power.” And since the Sicilian cannot be played without tactics, this new February release also fits the theme perfectly: Oliver Reeh’s new Master Class tactics volume offers exercises for players of all levels, regardless of their opening repertoire. | All photos: ChessBase
