The seventh game of the world championship chess match was adjourned Friday night when challenger Anatoly Karpov wrote down his 44th move and sealed it to be opened when play resumes.

Karpov appeared to have a significant advantage over the champion Garry Kasparov when the game adjourned because he had an extra pawn and observers felt he was in a winning position.Kasparov had entered Game 7 with a 31/2-21/2 point lead over Karpov, but if Karpov wins the game, the score in the match so far will be tied.

The game was scheduled to resume Saturday. Kasparov could agree to concede before then.
