The Senior Championship saw a tie for first place between GMs Larry Christiansen and Gregory Kaidanov, who will contest a rapid playoff Monday at 3pm Central time to decide matters. Kaidanov entered the day a half-point ahead of Christiansen, but could only draw against GM Igor Novikov after the players followed theory for 34 moves and neither could improve over a game between Kramnik and Anand.

This left an opening for Christiansen, who played brilliantly in a victory over GM Jim Tarjan. Winning against any GM with Black is tough, and as FM Robert Shylakhtenko explains in his Game of the Day annotations, Christiansen did an excellent job of keeping his chances alive and grinding his way to the playoff.
