The match started as a Four Knights Game and Svidler opted for the active Rubinstein variation. Black sacrifices a pawn but gets good compensation as white pieces are a little bit clumsy. Black challenged white’s foremost pawn on e5, but Morozevich didn’t want to dig in with 13.Bc2 and 14.f4, but instead went for the inspiring b4-b5 advance. Later, we learned from Morozevich that this was his attempt to activate the pieces on the Queenside. He was aware that black might have obtained a strong attack on the White King, but he decided to take the risk. White pressed the opponent’s c6 and d5-pawns, when black erred with the unfortunate e5-e4 push. This move was a logical attempt to grab the space and liberate e5-square for the pieces, but unfortunately for Svidler it had a tactical flaw. The point is that after 17…bxc6 18. Bxc6 Rxc6 black expected only 19. Nxf5 and then 20. Nxd5, but he missed that the immediate 19. Nbxd5 is coming in with crushing effect. Svidler tried to cause some trouble on the Kingside, but this was too slow as White simply captured everything on his way and promoted a new Queen on a8. Morozevich said in the press conference that his computer broke down last night and he couldn’t access his database. The only files that were available were on the Four Knights Game, so he was forced to go with this opening.
