The one team that got two wins on day two of the FIDE chess.com Nations Cup was Europe. Captained by Garry Kasparov, the Europeans have collected five match points overall and are tied in second place with the United States, after beating the Americans in a key encounter of round four. In round three, they had defeated India by the smallest of margins thanks to a remarkable win by Levon Aronian, who went on to score a second straight full point when he took down Leinier Dominguez.
China are still leading, as they are the only team not to have lost a match yet. On Wednesday, they gave up the first match point of the event when they drew Russia in round three.
The double round-robin section of the tournament will decide the two teams that will play in Sunday's final. By now, it seems unlikely China will not get one of the two spots, while Europe, United States and Russia are well ahead of Rest of the World and India in the fight to reach the conclusive match-up.
Rarely do we get to see the kind of trick Armenian star Levon Aronian employed to defeat Vidit Gujrathi in the only decisive game of Europe v India. The players had reached an ending with queens, four pawns per side and bishops of opposite colours. Vidit made the wrong passing bishop move, and Aronian quickly found the surprising winning manoeuvre:
If you want to become a strong player you have to study the endgame. That's just the way it is. Andrew Martin's DVD 'First Steps in Endgames' offers a superb introduction for players rated below 1600.
47.b4 wins. After 47...axb3 48.Bb2, Black's pieces are paralyzed — the light-squared bishop cannot move other than to b1 and the queen is stuck defending g7. Aronian quickly started pushing his a-pawn down the board and soon after got the win.
In the remaining games, both teams missed good chances — Harikrishna could not convert from a strong attacking position against Jan-Krzysztof Duda, while Anna Muzychuk was not precise enough to take advantage of his superior setup against Humpy Koneru. Vishy Anand and Maxime Vachier-Lagrave signed a correct 41-move draw.
In China v Russia, the day-one leaders found themselves quickly on the back foot, as Artemiev got a quick 25-move win over Wei Yi with the white pieces. The stars of the first two rounds, Yu Yangyi and Ju Wenjun, drew on bottom boards, which meant top seed Ding Liren needed to win to tie the score.
Ding was playing white against Ian Nepomniachtchi and apparently surprised his Russian colleague out of a Grünfeld Defence. 'Nepo' put up a strong fight, finding clever resources to complicate his opponent's task. Ding was as sharp as ever though, prevailing in the end and maintaining China's undefeated run in the event.
The United States' biggest weakness rating-wise lie in their female representatives, but in round three it was Irina Krush who gave the Americans a key victory over Rest of the World. The seven-time US women's champion played the Sicilian against Dinara Saduakassova, grabbed a pawn on move 15 and never looked back, eventually giving back the material but getting two strong connected passers on the e and f-files. Saduakassova resigned after 44 moves.
Hikaru Nakamura and Wesley So both had white and were held to comfortable draws by Teimour Radjabov and Bassem Amin, respectively, while Alireza Firouzja v Leinier Dominguez was a sharp fight that saw both players missing winning chances.
Given the standings after three rounds, Europe v United States was the key match of round four. Nakamura drew Vachier-Lagrave with black on board one, and, by then, Nana Dzagnidze already had a clear advantage over Anna Zatonskih — the Georgian eventually converted her edge into a win. But Dzagnidze was not the only player from the Caucasus that would succeed in that round, as Aronian played a sideline of the Petroff with black and went on to almost mate Dominguez after a sharp fight:
The Petroff (or Russian) Defence which is characterised by the moves 1.e4 e5 2.Nf3 Nf6 has been popular at the highest levels for many years and enjoys the reputation of being an extremely solid defence.
White's passers look dangerous, but Black's rooks on the second rank are just lethal. Dominguez resigned after 47...Rg2+ 48.Kh1 Nh3 with mate-in-3 on the board.
The last game to end was Anish Giri v Wesley So, in which So kept trying to squeeze a win from an equal 3v2 rook endgame. The point was split after White's 88th move.
The Chinese got their third victory of the event against India. On board four, the two highest-rated women players revived a long-standing old rivalry, as Humpy Koneru and Hou Yifan ended up drawing a 38-move game. Anand had some difficulties but managed to hold the balance with black against Ding on top board, while Harikrishna did the same against Yu.
It was Wang Hao's turn to give his team match victory. The 30-year-old inflicted Vidit's third defeat of the event after the Indian lost the thread with white as early as move 17.
Russia remained in the fight to reach Sunday's final by getting a 3:1 win over Rest of the World. Sergey Karjakin, who made his debut on day two, beat Jorge Cori on board three, after the latter missed a chance to get the upper hand on move 23, while Nepomniachtchi bounced back from two consecutive losses by defeating Teimour Radjabov on top board. Both Karjakin and Nepomniachtchi were playing white.
Firouzja was a pawn up against Artemiev but could not break the defences of the talented Russian, finally agreeing to a draw on move 77. Olga Girya also made her debut on Wednesday, and split the point with Mariya Muzychuk in an 84-move game.
