Position No. 6084: White to play and win. From the game Craig Clawitter-Leigh Hunt, La Palma 2009.

Solution to Position No. 6083: White wins the Queen with 1 Nc7+ Kb8 2 Bb5!, as 2 . . . Qxe4 leads to mate by 3 Nxa6+! bxa6 4 Bc7+ Kc8 (or 4 . . . Ka7 5 Qb6+ Ka8 6 Qxa6 mate) 5 Bxa6+ Qb7 6 Bxb7+ Kxb7 7 Qb6+.

The 45th annual American Open ended in a three-way tie last Sunday at the Renaissance Hotel in Los Angeles. Two favorites, GM Melikset Khachiyan and IM Andranik Matikozyan, shared first place with 20-year-old Julian Landaw. All scored 6-2 in the 36-player Open section, which included 16 masters.

Landaw, a master since 2006, achieved the greatest success yet in his chess career. He had to take a last-round bye that evening to return to college at UC Berkeley.

The three winners drew among themselves and with IM Vladimir Mezentsev. Khachiyan and Matikozyan defeated state champion IM Enrico Sevillano, who tied for fourth place at 5-3 with Mezentsev, Tatev Abrahamyan and Takashi Iwamoto.

Other sections were won by Jared Tan (under-2200); Fei Yue Yang (under-2000); Zheng Zhu (under-1800); Asatour Dovlatyan (under-1600); Alexander Magganas (under-1400); and Suresh Jhunjhnuwala (unrated).

Organizer Randy Hough described the turnout of 197 players as "rather disappointing." The tournament was one of the country's largest in the 1980s, consistently attracting over 400 entrants.

On the other hand, attendance boomed to 144 players in the American Open Scholastic. Sean Manross (grades K-12); George Situ (grades K-8, on tiebreak over Ezekiel Liu), Kumann Liu (grades K-6); and Eli Minoofar (grades K-3) led their sections.

Masters Robby Adamson, Harutyun Akopyan and Mick Bighamian shared first place with scores of 7 1/2 -2 1/2 in the Quick chess (10-minute games) event, which attracted 33 entrants. Roger Norman won the 22-player Action (30-minute games) tournament with 4 1/2 - 1/2 .

World Cup

The World Cup in Khanty-Mansiysk, Russia, has reached the fifth of seven rounds of two-game matches. Only eight quarterfinalists remain from the field of 128 starters. Of the 10 U.S. players, Gata Kamsky of New York, the winner of the 2007 World Cup, lasted longest. He won two matches before losing to 16-year old Philippine grandmaster Wesley So, who also upset pre-tournament favorite Vassily Ivanchuk of Ukraine. Varuzhan Akobian of North Hollywood, Alexander Onischuk of Virginia and Alexander Shabalov of Pennsylvania were eliminated in the second round.

The tournament is scheduled to conclude Dec. 15.
