Шахматы. Кубок наций 2020 (день 1). Не лучший старт российской сборной

Сборная России представлена на Кубке наций следующим составом:

При отсутствии Алексанра Грищука, состав вряд ли можно назвать оптимальным. В последний момент Грищук был заменен Артемьевым.

В турнире принимают участие шесть сборных: России, США, Китая, Индии, Европы и сборная остального мира.

Против сборной Европы российская команда сыграла с приемлемым результатом (2:2), а вот против американцев результат не радует (1:3).
