Neither team at the top could get an advantage, with all four games ending in stalemates, despite the defending open champions boasting high-profile names such as Alexander Grischuk and Kirill Alekseenko.

Both nations are on a record of three wins and two draws and are joined by four others, including Armenia, who moved up to fifth with a one-point victory over France.

Alireza Firouzja got the opening victory for the French against Gabriel Sargissian, before wins for Robert Hovhannisyan and Samvel Ter-Sahakyan against Maxime Lagarde and Jules Moussard turned the tide.

Hungary remain in fourth following a draw with Spain, while Ukraine are up to third after beating Georgia by one point, with only Andrei Volokitin's win over Tornike Sanikidze separating the two nations.

A similar score came for The Netherlands who moved up to sixth with a win over Serbia, with the only win going to Jorden van Foreest against Ivan Ivanisevic.

In the women's event, Russia maintained their 100 per cent winning record with a win over Italy, who suffered their first defeat.

Kateryna Lagno and Polina Shuvalova recorded victories over Marina Brunello and Elena Sedina, cancelling out a win for Italian Olga Zimina over Valentina Gunina.

In second are Georgia, who defeated Armenia thanks to wins for Nana Dzagnidze and Salome Melia over Elina Danielian and Anna M. Sargsyan.

Ukraine and Azerbaijan remain in the top eight with a draw between them, while Greece moved into third with a victory against France.

The crucial win - with the other three matches ending in stalemates - saw Anastasia Avramidou beat Pauline Guichard.
