Challenger Anatoly Karpov held an advantage throughout Game 9 of the World Chess Championship Wednesday night but dashed his own hopes of a win with a blunder at move 32 that forced the two grandmasters to a draw.

Karpov offered the draw two moves after he played Bd2, a move that many grandmasters felt was a "horrible" blunder and one that even his own camp of advisers admitted was not his intended move, said championship spokesman Eric Schiller.That move would have allowed Kasparov to have a pawn advantage "temporarily" but could only result in a draw thereafter, he said.

The masters play Game 10 Friday night. After five weeks or when 12 games are completed, the games move to Lyon, France, for the second half of the contest for the winner's share of a record $3 million.

Each player has one win. There have been seven draws.
