Sharp chess was the norm in round 5 of the U.S. Championships. Fabiano Caruana scored a third win in a row to keep his leading spot in the standings; Hans Niemann beat Levon Aronian to climb to sole second place; Leinier Dominguez and Wesley So grabbed their first wins of the event; while Ray Robson obtained a memorable victory over Jeffery Xiong.
Out of a Petroff Defence, Robson played the most trying continuation on move 15.
15.f5 gives up a pawn to 15...Rxe5, but after 16.fxg6 hxg6 White gets a dominating bishop on the long diagonal with 17.Bd4. At that point, Black’s best reply was 17...Re6, which would have avoided the spectacular game continuation. Instead, Xiong played 17...Re8 — and Robson went for it!
After 18.Rxf7 Kxf7 19.Rf1+ Black is forced to escape with his king to the centre — 19...Ke7 was Xiong’s choice (that is why playing ...Re6 on move 17 would have prevented Robson from playing the rook sacrifice).
Engines still evaluate the position as equal after 20.Qxg6, and only give White a large advantage after 20...Be6. Robson now has a winning attack.
White is now ready to harass the king on the weakened dark squares. There followed 21.Qg7+ Kd6 22.Be5+ Kc5 23.Bd4+ Kd6 24.Be5+ Kc5 25.Bc7
There is no way out: the black king is running out of squares. Xiong found the best way to muddy the waters, but Robson did not falter in calculating the winning lines — particularly impressive was his 27.Ne4+, which is in fact the only move that keeps his advantage.
27...dxe4 fails to 28.Rf5+ Bxf5 29.Qc3+ Kd5 30.Qe5+ Kc4 (diagram below) 31.b3+ Kb4 32.Qa5#, and White would have given mate while two rooks down!
In this video course, twenty-nine examples with multiple questions are presented in the interactive format, which is ideal for a range of playing strengths. Step by step you will be taken through the complex positions.
Xiong did not take the knight, but nonetheless was forced to resign two moves later. Robson recovered from a subpar start in style, as he now has 2 out of 5 points in the standings.

Niemann also showcased great tactical ability in his round-5 victory. Playing black, Aronian realized that he needed to give up a piece to avoid a quick loss. The tricky Armenian-born grandmaster got a pawn in exchange, and tried to make the most of his activity on the kingside from that point on.
25...b6 allows 26.Qxc6 Qxc6 27.Bxc6, but after 27...Rxh4 28.Nf3 Rg4 29.Re1 Rh8, Black is threatening to wreak havoc around White’s king with his pair of rooks.
A tactically alert Niemann immediately found 30.Rxe3, the best move in the position.
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.
White emerged with two minor pieces for a rook, and needed to work until move 63 to convert his advantage into a win. Beating a super-GM is never easy!

The women’s championship also saw five out of six games ending decisively, and there was no lack of excitement either.
Carissa Yip and Gulrukhbegim Tokhirjonova entered the round sharing the lead, and both won to remain atop the standings; Irina Krush beat long-time rival Anna Zatonskih and now stands in sole second place; prodgy Alice Lee grabbed a second consecutive win and returned to a fifty-percent score; and defending champion Jennifer Yu collected her first win of the event, as she defeated 2-time national champion Nazi Paikidze.
Yip beat Tatev Abrahamyan with the black pieces. Abrahamyan faltered on move 21, and Yip had not trouble finding the refutation.
White spent almost 9 minutes calculating before going for the attack with 21.Qh6 — but Yip had seen further, as she quickly captured the unprotected knight with 21...Qxc3+. After 22.Kf1 Bg7 23.Rg1, the key defensive move is 23...Bg4
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.
Abrahamyan needs to use an extra tempo in 24.Qg5, and her attack has already fizzled out. Soon after, it was clear that Black simply had a massive material advantage with no counterchances for White. Resignation came on move 28.
