Ukraine take down the top seeds
Find below videos from the venue by Arne Kaehler and expert analysis by GM Daniel King and IM Robert Ris.
Round 4 of the Chess Olympiad in Budapest produced decisive outcomes across the top nine matches, with eight teams now tied for first place, all holding perfect 8/8 match points. Two of the most surprising results came from Ukraine and Vietnam, who each secured significant victories. Ukraine stunned the top-seeded United States, while Vietnam handed a defeat to defending champions Uzbekistan, who are seeded fourth this year. These unexpected wins have shaken up the standings and added intensity to the competition.
Ukraine's victory over the United States came courtesy of strong performances from Anton Korobov and Vasyl Ivanchuk. Korobov defeated Ray Robson on board 4, while Ivanchuk, on board 2, managed to profit from a blunder by Wesley So. Fabiano Caruana continued his excellent form, winning his third game in as many rounds by beating Andrei Volokitin, but his efforts were not enough to salvage the match for the US. Ivanchuk's win was particularly noteworthy, as the 55-year-old had previously announced his retirement from chess after losing to a 16-year-old So at the 2009 World Cup.
In this Fritztrainer: “Attack like a Super GM” with Gukesh we touch upon all aspects of his play, with special emphasis on how you can become a better attacking player.

Vietnam's 3-1 triumph over Uzbekistan was equally impressive. Le Quang Liem, playing on board 1, controlled his game against Nodirbek Abdusattorov, while Nguyen Ngoc Truong Son and Le Tuan Minh delivered wins over higher-rated opponents on boards 3 and 4. This well-rounded performance propelled the Vietnamese team to face Poland, the 11th seeds, in Sunday’s fifth round.
In addition to Ukraine and Vietnam, six other teams are sharing the lead with 8/8 match points: India, China, Hungary, Poland, Azerbaijan and Spain. India has been particularly dominant, scoring 15/16 points on individual boards so far. Their standout player, Arjun Erigaisi, has maintained a perfect 4/4 record on board 3, consistently delivering crucial victories for his team.
Just 1 match point behind the leaders, four teams remain in close contention, including Norway, led by Magnus Carlsen. Carlsen secured a comfortable win over Slovakia's Viktor Gazik in round 4. Among the most surprising teams in this group is Türkiye, the 22nd seeds. Their youthful squad, featuring 15-year-old Ediz Gurel and 13-year-old Yagiz Kaan Erdogmus on boards 2 and 3, has been performing exceptionally well, with both teenagers holding perfect 4/4 scores.

Ukraine v. USA
In an endgame with two rooks, a pawn and a knight against two rooks and four pawns, So faltered on move 44.
Ivanchuk v. So
Black should focus on dealing with his opponent's threat of attacking the f7-pawn - grabbing that pawn would also defend a potential doubling of the rooks along the third rank. Thus, the correct way to continue is with 44.Kg7 Rd7 45.Kf6 Rbb7 46.e5, and the battle goes on.
Instead, So's 44.Re2 allowed 44...Rb7 (not 44...Rd7 45.e5 Rxf7 46.e4), and after 45.Re5 Rxf7 46.g5 Ivanchuk found 46...h5, when Black would need to make major concessions to prevent White from giving checkmate.
