American Cup: Missed chances in the open, three winners in the women's

by Carlos Alberto Colodro
3/16/2025 – The 2025 American Cup began with contested battles in both the open and women's sections. In the open section, all four games ended in draws, with top seeds Fabiano Caruana and Hikaru Nakamura failing to convert with the white pieces. Meanwhile, the women's section saw three decisive games, as Irina Krush, Alice Lee and Carissa Yip secured victories. Yip's win was particularly dramatic, as her opponent, Thalia Cervantes, missed a forced checkmate before ultimately collapsing. | Photo: Crystal Fuller

Open: Caruana and Nakamura miss chances

The opening day of the fourth edition of the American Cup featured tightly contested games, with all four encounters in the open section ending in draws. The top seeds, Fabiano Caruana and Hikaru Nakamura, both had the white pieces but failed to capitalise on their positions, leaving them vulnerable in the second games of their two-game matches.

Caruana built a significant time advantage against Ray Robson, but the latter, known for his ability to navigate time trouble, managed to escape with a draw by threefold repetition. Meanwhile, Nakamura faced Abhimanyu Mishra in a technical rook endgame. Despite Abhimanyu's inaccuracies, Nakamura was unable to convert his advantage into a win in a rook ending. GM Karsten Müller provides a detailed analysis of the missed opportunities in this complex endgame below.

The other two games of the day also ended in draws. Wesley So and Leinier Dominguez concluded the first game of the round without decisive action, while Levon Aronian's encounter with Sam Sevian lasted 40 moves before the players agreed to a draw.

With all matches still level, the second games of these encounters will be crucial. Caruana and Nakamura, in particular, must now hold with the black pieces to avoid being sent to the elimination bracket.

Cut-off festival. This weapon can be used by attacking and defending king: 80...Ra2? Black's king had to be improved first. After 80...Kf6 81.Ra5 Ke6 82.Ra6+ Ke7 Black gets a drawing setup, e.g. 82...Kd5? 83.Rf6 Rf1 84.Rxf5+ Rxf5 85.e4+ Ke6 86.exf5+ Kxf5 87.Kc4+- 83.d5 Rh2 84.Kd4 Re2 84...Rh4+? 85.Kc5+- 85.Re6+ Kd7 86.Rf6 Rd2+ 87.Ke5 Rd3 88.Rf7+ Ke8 89.Rxf5 Rxe3+ 90.Kd6 Ra3= 81.e4?

Now the cut-off on the e-file is decisive.
81...fxe4+ 82.Rxe4 Kf5 83.Re8 Ra4! The only defence. 83...Ra1? 84.d5 Ra4 85.Kc3 Kf6 86.d6 Ra7 87.Kd4 Ra4+ 88.Kc5 Ra5+ 89.Kb6 Rd5 90.Kc6+- 84.Kc3 Kf6! The king must retreat. 85.d5 Now both kings are cut off and so a draw follows. Kf7! 86.Re2 Kf6 87.Re1 Kf7 88.Re6 Rh4 89.Re2 Ra4 90.Re1 Rh4 91.Re5 Ra4 92.Re1 Rh4 93.Re6 Ra4 94.Re1 Rh4

Women's: Three winners, Cervantes misses checkmate

The women's section got off to an eventful start, with three out of four games ending decisively, all favouring the player with the white pieces. The two former champions of the event, Irina Krush and Alice Lee, both began their campaigns with victories. Krush defeated Atousa Pourkashiyan, while Lee overcame Nazi Paikidze. Carissa Yip also secured a full point, beating Thalia Cervantes in a dramatic and unexpected turnaround.

Yip's victory was the most striking of the day, as she was on the verge of defeat before Cervantes missed a straightforward winning sequence. Cervantes had built a winning position and reached a decisive moment on move 35, where she had a forced mate-in-four.

Yip v. Cervantes

35...Qe5+ 36.Kf2 Qe2+ 37.Kg1 Qf1#. However, instead of delivering the winning sequence, she played 35...Bd5, missing her opportunity. This allowed Yip to respond with 36.Bxd7+ Kxd7 37.Qd2, pinning Cervantes' bishop and shifting the dynamics of the position.

Yip gradually consolidated her advantage, and despite Cervantes' attempts to defend, she eventually collapsed, allowing Yip to convert the advantage into a win after 66 moves.

Meanwhile, the only drawn game of the round saw Tatev Abrahamyan converting her advantageous middlegame position into a queen and knight endgame, which was also favourable but gave more chances for the player on the defensive side. Anna Zatonskih showed her technical prowess to escape with a draw.
