Kasparov Draws Game 4 and Match Against X3D Fritz
jaydee77ca writes "Garry Kasparov survived opening danger and played very precise, technical chess to draw Game 4 with black against X3D Fritz. The final match result is a 2.0 - 2.0 draw, proving yet again that the day of the machines has not yet arrived."
The players alternate white and black pieces each game. White has an advantage in chess (due in part to it making the first move). Having an odd number of games would give one player the white pieces in one extra game thus giving that player an unfair advantage in the match.
