National Open: five players share first

The National Open is a traditional tournament that is played over five days with a lot of double rounds. Participants can take part in different events, either over three, four or five days and over nine rounds or seven rounds. This is probably also where the "bye" was invented for the players who have very little time: You sit out a round and still get half a point. In addition to the Open, there are numerous junior competitions.

Walter Tevis' novel The Queens Gambit also mentions the tournament, in which Tevis played in the 1970s.

The Open started last Wednesday and ended the following Sunday. Among the more than 130 participants in the main tournament were numerous grandmasters and some well-known names such as Gregory Kaidanov, Alexander Yermolinsky, the young Hungarian GM Benjamin Gledura, online bullet expert Andrew Tang, the former FIDE Vice World Champion Vladimir Akopian, who lost here in Las Vegas in 1999 to Alexander Khalifman in the final of the FIDE Knockout World Championship, "Blindfold King" Timur Gareyev or the Cuban grandmaster Lazaro Bruzon.

Gareyev is known for his original style and his crazy ideas, not only at the board.

The Elo favourite was Ukrainian-born Ilya Nyzhnyk (2679). In his younger years Nyzhnyk played some time in Germany in the Second Bundesliga before emigrating to the USA.

Nyzhnyk finished with 7.0/9, as did four other players: Andrew Hong, Emilio Corodva, Lazaro Bruzon and Arthur Guo. Of these, 15-year-old IM Arthur Guo had the best tiebreak and won the tournament.

In round 7 Guo had Black against Hans Niemann and outplayed the grandmaster from the U.S.

 
H. Niemann - A. Guo

23... Bxf2+ 24.Kh1? A step in the wrong direction. Better was 24.Kxf2 Rc2+ 25.Kg1 Rxb2 26.Ne7+ Kh8 27.Rab1 and White can still fight for a draw.

24...Rc2 25.Be5 25.Rab1 Rd8 26.Be5 Be2–+

25...Bc5

 

26.Rac1 Black threatened 26.-- Rd8, causing White great problems on the diagonal b7–h1, e.g.: 27.Be4 Rxd1+ 28.Rxd1 Be2 29.Bxc2 Bf3#

26...Rxc1 27.Rxc1 Rd8 28.Bg2 f6 29.Bf4 29.Ba1 Rd2 and White can hardly move.

29...Bd3 30.Ne3 g5 and the bishop is trapped. 0–1
