1.e4 e6 2.d3 d5 3.Nd2 Nf6 4.Ngf3 b6 5.c3 Be7 6.e5 Nfd7 7.d4 c5 8.Bb5!? In order to be able to answer ...Ba6 with a4!
8...a6 I am not sure whether this is correct or not. To my mind, shutting in the black c8-bishop and chasing white's bishop to a better square doesn't look very logical. However, by advancing his queenside pawns, black does get some active play in return, so I still wouldn't call 8...a6 a mistake. [8...Ba6 9.a4 Qc8 is the main line]
9.Bd3 b5 10.Nf1 intending Ng3-h5-f4. [After 10.O-O the white's knights will have trouble finding good squares.]
10...Nc6 11.Ng3 b4 12.Nh5! Provoking black to weaken his kingside.
12...g6 [12...O-O is quite risky, for example: 13.Nf4!? (to prevent ...f6) 13...Rb8 14.h4! threatening Bxh7, and black already has to be very careful]
13.Nf4 Qb6 14.Be3 bxc3 15.bxc3 cxd4 16.cxd4 Qa5+ 17.Kf1! A standard idea in these positions: instead of castling, white just puts his king on f1 and leaves the rook on h1 to support the h-pawn. [17.Bd2 Qb6 18.Be3 Qa5+ leads nowhere]
17...Nb6 18.h4 White prepares to open up the kingside.
18...Bd7 19.a3 Played in order to restrict black's pieces.
19...Qa4 20.Bc2 Qb5+ 21.Nd3 Nc4 22.Bc1 Qb6 [22...Qa5!? , intending ...Qc3, looks like a good alternative.]
23.Rb1 Qa7 24.Nb4 Nxb4 25.axb4 h5 [25...O-O-O - to me this looks like black's best chance to fight. White probably still has the better chances, but it's certainly not so easy to break through.]
26.Rh3! Activating the rook and intending Ng5 followed by Rf3.
26...Rb8 27.Ng5 Rxb4? This risky pawn-grab actually seems to lose by force. [However, black's position was already quite critical, for instance: 27...Bxb4 fails beautifully to 28.Nxf7 Kxf7 (28...Bb5 29.Kg1 Qxf7 30.Rf3 Qg7 31.Rxb4) 29.Qf3+ Kg8 30.Rg3 and white wins]
28.Rxb4 Bxb4 29.Rf3 Bb5 30.Kg1 O-O!? After 30 moves in the middle of the board, the black king finally finds time for castling. During the game I was quite surprised by this move, thinking that his only option was Rf8, but it turns out that white still has a strong attack: [30...Rf8 31.Nxf7 Rxf7 32.Bxg6]
31.Rg3 Threatening Nxe6.
31...Kh8 [31...Be8 32.Nxe6 fxe6 33.Bxg6 wins for white.] [31...Qe7 32.Nh7! and white wins.]
32.Qf3 Qe7 33.Nh7! Rc8 [33...Kxh7 34.Qxh5+ Kg8 35.Bxg6 fxg6 36.Rxg6+ Qg7 37.Rxg7+ Kxg7 38.Bh6+ and white wins.]
34.Bg5 Nd2 35.Bf6+
