USSR Championship Semifinal — Nikolaev 1981
Incomplete record. This archive holds 36 games of this event; the others are missing, and the number played is not established. Five documented played pairings are unavailable; four preserved scores begin from recorded middlegame or endgame positions.
Vladimir Tukmakov won this sixteen-player USSR Championship semifinal with 11/15. The collection preserves thirty-six scores from the fifteen-round event.
The surviving games
Five documented played pairings are unavailable: Eingorn–Tukmakov, Mikhalchishin–Zilberstein, Kantsler–Zilberstein, Kantsler–Pigusov and Levchenkov’s 107-move encounter with Tukmakov. The colors of the last game are unestablished. The full number of games actually played remains unknown.
Four preserved scores begin from recorded middlegame or endgame positions. Their earlier moves are unavailable; the displayed positions and surviving moves are retained.
A result later annulled
Levchenkov–Sher was played and initially recorded as a win for Black. A later ruling annulled the result and assigned both players losses. The score keeps its original result, with the later ruling stated here. No final cross table is calculated from the surviving scores.
The Zilberstein identity
The contemporary report names V. Zilberstein, and its printed Gufeld–Zilberstein continuation matches the preserved game. The five affected records identify Valery Zilberstein; the source’s David Zilberstein attribution is corrected for these exact games. Source ratings are preserved.
Result
The surviving scores do not form the final official table. The played Levchenkov–Sher game was later annulled and both players received losses; its recorded result is preserved with that ruling explained.
