The September list is out, and August belonged to Praggnanandhaa. He won the Saint Louis Rapid & Blitz, then tied for first at the Sinquefield Cup and lost the playoff to Wesley So, then came back a week later and won the Grand Chess Tour Finals anyway, beating Keymer in the semi and Caruana in the final. The rating side of all that is quieter than the trophy side: 2761 in classical, which is enough to pass Erigaisi for India's #1 spot by two points, and 2730 in rapid.
So takes nine rating points from the Sinquefield win. Nakamura did not play a rated game all month and is the new USA #1 anyway, because Caruana gave back three in classical. The rest of Saint Louis was expensive: Caruana dropped out of the rapid 2700 club, So lost 19 blitz points across 28 games, and Jorden van Foreest went 2/9 in the Sinquefield Cup (yes, 2/9). Nobody joined or left the classical 2700 club. The most watched chess of the month, Carlsen beating Lazavik in the Esports World Cup final in Paris, was not FIDE-rated.
The girls' junior list turned into a proper race. Modipalli Deekshitha went from 2157 to 2454 in a single list, on two opens in Portugal and Spain, the biggest gain by any woman in the world this cycle. That puts her third among the girls' juniors, and the top four are now inside twelve points: Anastasiia Hnatyshyn, Alua Nurman, Deekshitha and Alice Lee. Lee took second at the Cairns Cup behind Tan Zhongyi with a GM norm, a week after beating Hou Yifan in the Women's Speed Chess final. Nurman, born 2007, is the oldest of the four.
On the boys' side, Yagiz Kaan Erdogmus, 15, is still the world junior #1 at 2716, thirteen clear of Gukesh, who sat August out. Aditya Mittal won the Slovak Masters in Skalica on tiebreak from Abhimanyu Mishra and Dardha, in a field that was mostly 2600s. Yahli Sokolovsky of Israel won the European Junior title in Cetinje, and Eline Roebers the girls' title. Vyom Malhotra, born 2014, went 2297 to 2438 in nine games at the Czech Open, with an IM norm along the way.
The strongest fields of the month were not the obvious ones. The Turkish Super League had twenty players rated 2600 or better (I wrote about it last month), the Sinquefield Cup had ten, and eight of the ten at the Rubinstein Memorial in Polanica were, which Awonder Liang won. Etienne Bacrot won a record ninth French title, beating Lagarde in the final. Alan Pichot won the Spanish title, and Jaime Santos Latasa won both the Spanish blitz and the Spanish rapid in the same weekend. Shreyas Royal, 17, won the British Championship ahead of McShane and Adams, the youngest British champion there has ever been, and in the same hall Bodhana Sivanandan took the women's title at 11. Elham Amar took the Sparkassen Trophy in Dortmund and Jakhongir Vakhidov won the Abu Dhabi Masters.
Events that finished in August produced 19 GM norms and 99 IM norms, plus 17 women's norms. Or Bronstein had the summer of his life, winning the Arad Open and finishing second on tiebreak at Kanizsa, behind Pranesh; he is over 2500 for the first time and has three GM norms on FIDE's register. Anatole Vlachos also has his three, at 2504. Khagan Ahmad, 15, crossed 2500 with his first GM norm from the Turkish league. Felix-Antonio Ilinca, born 2010, and Svyatoslav Bazakutsa are one norm away.
Ten federations have a new classical #1. Pavel Eljanov is Ukraine's again. Poh Yu Tian, born 2009, hit 2500 on the nose with a GM norm in Dortmund and now leads Malaysia. Kukudzarema Shepherd is Zimbabwe's #1 on the published list after a +186 August. Another ten women's #1 spots changed hands; Armenia's went back to Elina Danielian, born 1978.
Alireza Firouzja finished level on points with the winner Mamedov in the Balkan rapid championship in Sofia on the last weekend of August, then won the blitz outright the next day. None of it is in the September numbers yet. Neither is the Sants Open in Barcelona, where two Indians born in 2012, Shaurya Chaudhary and Aarav Amonkar, gained 189 and 157 points and are now 2419 and 2400 live, or the Slovak Open, the open section of the Skalica festival Mittal won, where Zsombor Pasti of Hungary, born 2009, picked up 108.
48,897 people played a classical game this cycle, 36,663 played rapid and 24,290 played blitz. Behind Deekshitha, the biggest classical gain by anyone over 2300 was Vedant Varasada, born 2010, +231 to 2464. Gleb Scheglov, born 2010, led rapid with +152 to 2364, and Martin Krauchi Romero of Spain, born 2011, led blitz with +176 to 2366.
