The U.S. Championship: Nakamura and Kamsky Lead. The Endgame with Three Queens

Время публикации: 11.05.2012 19:00 | Последнее обновление: 15.12.2012 17:45

The rating favourites Hikaru Nakamura and Gata Kamsky grabbed lead after winning their 3rd games in the U.S. Championship which is held in Saint Louis. Now they have 2.5 points each.

Nakamura beat Ray Robson who played the Sicilian Dragon variation choosing 9.g4 Be6 10.Nxe6!? - a quite rare continuation, which repeatedly takes place in recent year's games of professionals. 

NAKAMURA - ROBSON

Robson's novelty 16...Nb6?! turned out to be doubtful. After 17.h5 White develops initiative. Robson lost an exchange, the doubled pawns served him as a compensation. Despite his desperate resistance, the favourite won.   

Kamsky played, as he sometimes does, 1.d4, 2.Bf4, 3.e3, 4.c3 system (or the wedge), he gradually outplayed such a strong opponent as the former U.S. champion Alexander Onischuk. 

The veteran Yasser Seirawan lost the 3rd game in a row, this time against Yury Shulman. Up to the 19th move Shulman playing White got a better endgame, Seirawan, the repeated champion of the country, failed to hold. Alexander Stripunsky broke a string of unsuccessful games by winning over Varuzhan Akobian.

After Anna Zatonskih drew against Sabina Foisor, the women's championship has also lost the player with the perfect score. The main favourites Zatonskih, Irina Krush and Iryna Zenyuk lead with 2.5/3. 

It's hard to ignore the endgame with the unusual number of queens. 

KATZ - BAGINSKAITE

Earlier Black missed a chance to win, now it misses a draw as well:
34...Qxh2+?
Black could hold only after 34...Qg2+!!.
35. Kxh2 Qc2+ 36. Kh1 1-0
