Ohanyan Wins Atyrau Masters on Buchholz After Tie With Jiang, 15

Armenian GM Emin Ohanyan won the Atyrau Masters after finishing level on 7/9 with 15-year-old Chinese IM Jiang Haochen. The tiebreak decided it: Ohanyan’s Buchholz cut-1 was 46, Jiang’s 36½.

The event ran from 12 to 20 October as the third stage of the Kazakhstan Chess Cup. It was a nine-round Swiss with 109 players in the Masters section, at 90 minutes plus a 30-second increment per move. First prize was 9 million Kazakhstani tenge, roughly US$20,000.

Two favourites stumbled early

The top two seeds were wounded almost at once. Shamsiddin Vokhidov (2649) lost in round one to Vietnam’s Nguyen Duc Hoa (2405). Leon Luke Mendonca (2629) lost in round two to Armenian IM Sergey Sklokin-Bagiyan (2477).

Neither recovered fully. Both finished on 5½/9, level with a pack of players who were rated well below them at the start.

Nguyen, the 2405 who beat Vokhidov, ended on 5½ himself. Sklokin-Bagiyan reached 6 and finished seventh. When the top seeds drop points that early, a Swiss field tends to cluster, and the title can go to whoever stays steady.

How Ohanyan got there

Ohanyan, 20 and rated 2520, was seeded 20th. He took five wins and a draw from his first six games, then drew the last three. That left him unbeaten on five wins and four draws.

His schedule was not especially brutal. He met only two players from the top ten seeds: Baadur Jobava (eighth seed) and Ivan Zemlyanskii (tenth), both drawn in the last two rounds. Those draws kept the lead but let Jiang catch him.

Jiang’s late surge

Jiang, rated 2490 and seeded 30th, came from behind. He finished with three straight wins, including one over seventh seed Arkadij Naiditsch in the penultimate round. In round nine he beat Sergei Lobanov to reach 7/9.

The two never played each other. Their routes explain the tiebreak gap: opponents who scored well early lifted Ohanyan’s figure, while Jiang’s late climb left him with a lower-scoring set of opponents.

Buchholz cut-1 drops the weakest opponent’s score and sums the rest. For more on how such tiebreaks work, see our Swiss-system explainer.

Behind the leaders

Three players finished on 6½/9, all undefeated: Georgia’s Jobava, Ivan Zemlyanskii and Kazakhstan’s Aldiyar Ansat. Jobava took bronze on Buchholz (47.5), ahead of Zemlyanskii (46) and Ansat (43.5).

Ansat was seeded 32nd, so the top five included three players from outside the top 15. Ohanyan, Jiang and Ansat were seeded 20th, 30th and 32nd.

Twelve players in the field were rated between 2550 and 2650. Of those, Aditya Mittal and Maxim Matlakov finished on 6, Pranav Anand and Gata Kamsky on 5½, and Naiditsch on 5. Matlakov and Mittal were within a point of the leaders.

Jiang’s rating is only 30 points below Ohanyan’s. A 15-year-old IM at 2490 sharing first with a GM is the kind of result that tends to move a junior’s rating quickly.
