Hans Niemann had been the only player to remain at a half-point distance from sole leader Fabiano Caruana after seven rounds at the U.S. Championship. However, playing black against Ray Robson, he suddenly allowed his queen to be trapped by his opponent — despite having a 45-minute advantage on the clock!
Navigating the Ruy Lopez Vol.1-3
The Ruy Lopez is one of the oldest openings which continues to enjoy high popularity from club level to the absolute world top. In this video series, American super GM Fabiano Caruana, talking to IM Oliver Reeh, presents a complete repertoire for White.
A time-trouble addict, Robson had been very careful not to let any tactical trick escape him in the opening and early middlegame of a theoretical Ruy Lopez. At this point, with six moves to go before reaching the time control, he had 4 minutes to Niemann’s 49.
Both the blunder 34...Qa3 and the refutation 35.Ra2 were played almost instantly.
The queen has nowhere to go. Resignation came after 35...Ba4 36.Qa1.

After this loss, Niemann remained in second place, but now a full-point behind defending champion Caruana, who drew Sam Shankland with white. Sharing second place with Niemann on plus-one scores are Leinier Dominguez, Wesley So and Abhimanyu Mishra.
At 14 and as the second-lowest rated player in the field, Abhimanyu is having a great run in the national championship. On Friday, he beat Sam Sevian with the white pieces. The teenager had an extra pawn in a bishop vs knight endgame, and managed to convert his advantage after Sevian incorrectly pushed his f-pawn on move 47.
The ending was analysed by our in-house expert, GM Karsten Müller.

There is no stopping the leading duo in the Women’s Championship. After each obtained a fourth consecutive victory in round 8, co-leaders Carissa Yip and Gulrulkhbegim Tokhirjonova now have a 2-point lead over Irina Krush and Alice Lee.
While Tokhirjonova outplayed Anna Zatonskih positionally to get a rather clean 32-move victory on Friday, Yip emerged victorious out of a rollercoaster battle against Atousa Pourkashiyan.
If we look at this position, it is surprising that it was Black who ended up getting a win. Despite being an exchange down, White has a strong initiative. And, indeed, Pourkashiyan could have obtained a remarkable victory had she found 54.Rc3 here, threatening to give a lethal check from c8 — e.g. 54...Qd6 fails to 55.g6, leaving the queen en prise to take away the h7-square from the black king.
It should be noted that both players had about a minute left on the clock at this point and were mostly ‘living on increments’.
Instead of the killer shot, White played 54.Qb8+, and after escaping with the king to f6, the worst had passed for Yip.
A few moves later, Pourkashiyan faltered again, except this time not by failing to find a winning manoeuvre but by entering a hopeless position.
Black is attacking the rook on g3 and, according to the engines, has a slight advantage.
Master Class Vol.16 - Judit Polgar
In this video course, experts (Pelletier, Marin, Müller and Reeh) examine the games of Judit Polgar. Let them show you which openings Polgar chose to play, where her strength in middlegames were, or how she outplayed her opponents in the endgame.
However, it was not the time to go for desperate measures — i.e. 58.Nh7+ allowing 58...Rxh7 to pin the knight with 59.Qf4, as was seen in the game. After the simple 59...Rhg7, Black is guaranteed further simplifications, and her material advantage is sure to give her the victory.
Instead of all this, White could have gone for 58.Nxf7, and the battle continues. With so little time on the clock, Yip would have probably struggled to find the more accurate moves to convert her advantage. It was a lucky break for the youngster, which keeps her tied for first as she fights to get her second U.S. women’s title.
