The JR Chess Report (August 29): Old Fogies Lead Young Whippersnappers in Amsterdam
Old Timers Lead Youth in Annual Team Match in Amsterdam



The annual Rising Stars-Experience team match is taking place in Amsterdam with the team of old timers posed to score their first match victory in the three-year-old series.

Experience (Alexander Beliavsky, Ljubomir Ljubojovic, Peter Heine Nielsen, Peter Svidler and Loek van Wely) leads Rising Stars (Fabiano Caruana, Hou Yifan, Hikaru Nakamura, Jan Smeets and Daniel Stellwagen) after eight rounds by a score of 22-18.

Yugoslav/Serbian legend Ljubomir Ljubojevic, 58, is anchoring the greybeards with 3 wins against a single loss and four draws. Reigning Dutch national champion Jan Smeets, who at 24 is the senior junior, has the same record to lead the youngsters, but he is the only member of the youth team with a plus score. Reigning US champion Hikaru Nakamura, widely expected to lead the Rising Stars before the event started, has been suffering the flu this week and playing poorly.

The leading player for the Rising Stars will win a birth in next year's Melody Amber Rapid/Blindfold Tournament in Nice.

The match is sponsored by NH Hoteles of Spain and the Association Max Euwe of Monte Carlo.

  • 29...Be5 30.Bxe5 Rxe5 31.h4 a6 is also playable.

    13. Update (Monday): Fogies 27½, Whippersnappers 22½ (Final)
    The Experience team scored its first victory in the three-year-old team match series against Rising Stars today in Amsterdam as the latest edition of the event ended in a 27½-22½ win for the old timers.

    Not-so-old old timers Peter Heine Nielsen (36) and Peter Svidler (33) were the top scorers for the Experience team with 6½ and 6 points respectively.

    Jan Smeets, the reigning Dutch national champion, was the only Rising Star to score better than 50% in the ten round match. Smeets had 6 points out of a possible 10. As the leading scorer on the Rising Stars, Smeets will compete in next Spring's Melody Amber Rapid/Blindfold Tournament in Nice, France. The past winners of the ticket to Nice from Amsterdam were Magnus Carlsen in 2007 and Sergey Karjakin in 2008.
