The highest-rated 15-year-old of all time claimed the number-15 spot on the live rating list following a hard-fought victory in round three of the European Chess Club Cup. Erdogmus managed to outlast his opponent despite cutting his own time to just six seconds before making his 32nd move. His win propelled him past two other strong players in the world rankings.

Two other notable debuts went smoothly for the top-seeded team. Giri and Abdusattorov both picked up victories in their first appearances at the tournament after sitting out the opening rounds. Giri's win came against established opposition, while Abdusattorov methodically outplayed his opponent to climb above another top American grandmaster in the ratings.

The favorites remained dominant across the open competition, with eleven of the top twelve teams maintaining perfect match records. However, a shocking upset did occur when van Foreest fell to a lower-rated opponent due to a single costly blunder on move 24. A few other minor upsets emerged elsewhere on the boards, though the seeded teams generally found ways to secure victories.

Monte-Carlo and Gambit Bonnevoie emerged victorious in the women's section, with both teams defeating their higher-seeded opponents through a combination of tactical precision and resilience. Top boards saw mixed results, with Batsiashvili unable to prevent her team's loss despite a personal victory. The women's matches featured several dramatic reversals, including one where an advantage turned into a defeat for a player who had been winning.

An 11-year-old prospect also made headlines in the women's competition, bouncing back from an earlier loss with a win against a higher-rated opponent. The young player's performance contributed to a strong showing by her lower-seeded team in round three. Round four is scheduled to bring matchups between the top teams, with nearly all boards featuring grandmaster-level competition.
