Skilling Open 2020 (день 6): итоги первых матчей полуфинала

27 ноября 2020 состоялись два полуфинальных матча:

Карлсен — Непомнящий
Накамура — Со

Фаворитом первого матча бесспорно являлся действующий чемпион мира Магнус Карлсен. В первой партии Карлсен — Непонящий была разыграна защита Грюнфельда. Непомнящий допустил фатальную ошибку на 15-ходу, которая в последствии привела к потере фигуры и проигрышу партии.

У черного коня нет безопасных полей для отступления
