An English opening with White with the reversed Hedgehog structure. Already after 8.b3 Caruana was unhappy with this opening and that is why he decided to exchange the light-squared Bishops. Morozevich might have felt Black’s discomfort as he immediately replied with aggressive-looking 11.h4. But Caruana kept his cool and calmly exchanged another pair of pieces to reduce the attacking potential. White gave up on the aggression as he castled Kingside and the play became slower and more positional. Black setup was very resilient and Morozevich decided to sacrifice an exchange in order to create some imbalance. Caruana however found a fantastic resource in 43…Rh7, which is at the same time defending and counter-attacking. White probably had good possibilities to make a repetition or perpetual, but the position was extremely complicated and after the excellent 46…Qb8 Morozevich immediately blundered. The Russian kept playing for awhile, but black easily converted the large material advantage.

Morozevich, Alexander (2760) – Caruana, Fabiano (2774)
