13. Ng3 Qc7 14. Qd2 Rad8 15. h3 h6!? This is probably new. The “book” continuation is 15 ... g6 16. Rad1 Bg7 17. Qc1 Nf8 18. dxe5 (or 18. Qa1 N6d7 19. Nf1 Ne6 20.

16. Rad1 Qb8? Black was still in time to re-enter through the window from which he has exited by 16. ... g6!?, in which case White would have probably continued with Qd2-c1, eventually followed by c2-c4 and Qc1-a1 with a certain edge.
17. Nf5 exd4? This is tantamount to disaster, even though Black’s situation seemed precarious enough already. Probably best was 17. ... b5, but then after 18. g4! (Δ g4-g5) White’s initiative can suddenly turn into a powerful attack.
18. N3xd4 c5. Already sacrifices on g7 and h6 are in the air, and Black has no good way to prevent all threats against his King.
