Chess notes

To celebrate its 150th anniversary, the world’s third-oldest chess club, Stockholm’s Chess Society, organized one of Sweden’s strongest chess events ever, the Hasselbacken Open (www.HasselbackenChessOpen.se). This 450-player, nine-round Swiss featured 34 grandmasters and 13 international masters. The top two seeds were Dmitry Andreikin of Russia with a FIDE rating of 2736 and the legendary “Fire on Board” specialist, Alexei Shirov of Latvia. The field also included two Americans, 15-year-old Sam Sevian of Southbridge, Mass., and 13-year-old Awonder Liang from Minnesota.

To get warmed up, Sevian played a 20-board simul the day before the tournament, winning all the games. In the tournament, he showed a new found maturity, playing one his best events ever. He was undefeated with 6.5 points, playing six grandmasters, drawing all but Shirov, whom he beat in a very exciting game. He gained 13.5 rating points, which pushed his rating over 2600 for the first time. He finished in 15th place on tie-break, but he was bested in finishing place by Liang, who finished in 13th with 7 points, again on tie-break.


Though he finished higher than Sevian, Liang had a poor event. He played only one grandmaster, lost in the second round to an “A” player, and gained no rating points.

The eventual tournament winner was Andreikin on tie-break over Baskaran Adhiban of India. Andreikin’s victory earned him 50,000 Swedish krona, or $6,136.50.
