(1) Carlsen,Magnus (2826) - Anand,Viswanathan (2800) [C65]
Grand Slam Final Masters Bilbao ESP (2), 10.10.2010

1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.d3
This line has become a main continuation to those wishing to sidestep the principal Berlin lines. Nepomniachtchi has been championing it this year, with four games in 2010 already, but others are following suit.

4...d6 5.0-0 Be7 6.c3 0-0 7.Nbd2 Bd7 8.Re1 Re8 9.Nf1 Bf8 10.Ba4 h6 11.Ng3 Ne7 12.Bb3 Ng6 13.d4 c5 14.h3 Qc7 15.a4 a6 16.a5 cxd4 17.cxd4 exd4 18.Nxd4 d5 19.exd5 Rxe1+ 20.Qxe1 Re8 21.Qc3 Qxc3 22.bxc3 Re1+ 23.Kh2 Bd6 24.Nc2 Rf1 25.Be3 Rxa1 26.Nxa1 Be5 27.Bd4 Bxd4 28.cxd4 Ne7 29.Nc2 Nfxd5 30.Ne4 b6 31.Ne3
[Or 31.axb6 Nxb6 32.Nc5 Bb5 33.Nb7 Bc4 34.Bxc4 Nxc4 35.Kg3 a5 36.Kf3 a4 37.Ke4= ]

31...Nxe3 32.axb6 N3f5

While not losing per se, this puts white in hot water and borderline lost. [33.d5 was the simplest and best. 33...Bc8 34.g4 (34.d6? Nc6 35.g4 Nfd4 36.Bc4 a5 37.Nc5 Be6 and white is in trouble as the black nights cover the pawns fine while the passed a-pawn will soon be a major problem.) 34...Nd4 35.Nd6 Bb7 36.Nxb7 Nxb3 37.d6 Nc6 38.d7 a5 39.d8Q+ Nxd8 40.Nxd8 Nc5 41.b7 Nd7 42.Nc6 a4 43.Ne5 Nb8 44.Nc4 and the position is equal.]

33...Nxd4 34.b7 Nec6 35.Ba4 Be8 36.Nxa6 Kf8 37.Kg3 Ke7

[White had to play 38.Bd1! which leads to a forced line (for him) in which he can survive if he walks the tightrope with care. 38...Kd6 39.Bh5 g6 40.Bd1 Bd7 41.h4 Be6 42.Ba4 Bc4 43.b8Q+ Nxb8 44.Nxb8 Ne2+ 45.Kh2 Nc3 46.Be8 and in spite of the anxious looking position of the knight on b8, Black has no forced win.]

Black is winning now.

39.Ke3 Ned8 40.Bxc6 Nxc6 41.h4 Kd6 42.g4 Bd7 43.g5 hxg5 44.hxg5 g6 45.f4 Be6 0-1
