12... Qb8 Black remove the queen from "с" vertical.

13. e4 Rfd8 Black keep up the tension, hoping after 14.е5 Ne8 to release the game with Ne8-c7 and с6-с5. 14. e5 Ne8 15. cd cd

The pawn structure suppose White will show some activity on King side. But it is not clear since Black king does not have weak points.

17. Bd3 Nf8 Black does not move any pawns where the opponent is trying to attack. 18. Qe2! Bc6 Black has an idea to move b5-b4 and after Bb5, to chage bishops.

19. Na4! Prevention. b6-b5 is impossible (Kс5), but after 19...B:a4 20.ba White even stronger on the Queen side. 19... Qb7 20. Rc2 a6 21. Rdc1
