31...Be6??
The Italian grandmaster missed the only chance to achieve a draw.
31...a3 32.Bd5 Rd1+ 33.Kg2 Be4+! 34.B×e4 a2 35.Ra7 a1=Q 36.R×a1 R×a1.
32.Bc8! Bb3 33.Ra7 +-

36...Bd7??
Black should have played 36...f5! in order to prevent White from carrying out 37.e5 and then 38.Ne4+.

37.Ra7 Kg7?
American Fide Master Dmitriy Volkov committed a meaningless move and put his king on a dangerous square.
He should have defended the e3 pawn with 37...Be3! and after 38.Bd5 Ng5, the f7-pawn would also be defended.

17... c6?
A wrong decision that activates opponent's pieces.
The correct is 17... Qf7+ 18. Kg1 Qf8! with the idea of ...Bh6, trading his bad bishop for White's good one.
18. dxc6 Bxc6 19. Kg1 Nc7 20. Be3 N7e6 21. b4 axb4 22. axb4 Na6 23. Nd5 Nac7 24. Nbxc7 Rxa1 25. Qxa1 Nxc7 26. Bxb6 Nxd5 27. exd5 Ba4 28. b5 1-0

19.c5!
A slower move would have been answered by 19...Bc5 and 20... 0-0.
19...Nxc5
By sacrificing a pawn White frees his bishop and succeeds in disrupting his opponent's build-up, as 19...Bxc5? 20.Bb5+ Kf8 21.Nb3! would embarrass the black knight and bishop on c5.
20.Bb5+ Nd7 21.Qc3! Preventing 21...Bc5.

32...h5!
If the white queen were still sitting on e3, this pawn advance could be countered by an invasion with Qh6+. Instead, her self-inflicted exile means that the flimsy white pawn cover on the g-file collapses as soon as the first blow is struck.
33.gxh5 gxh5 34.Nf5
The knight jumps before it is pinned with 34...Rg8, when 35...h4 would be on the cards.
34...Bxf5 35.exf5 Rg8+ 36.Bg2 Qg7
The black queen takes advantage of her unchallenged dominance of the g-file to compel White to shut in his bishop and further weaken his dark squares.
