Sergash: Matthias Womacka is a German player born in 1966. He became FIDE master in 1985, International Master in 1990 and then Grandmaster in 2010.<2...e6> Carlsen had switched from 2...e6 to 2...d6, before adopting 2...Nc6 for a while. This is a come back to 2...e6.
<4...a6> In a previous game B Kvisvik vs Carlsen, 2001 Carlsen had played here 4...Nf6 5.Bd3 d6 6.Bb5+ and both players had agreed to a draw here!
<5.Bd3> More played has been 5.Nc3 Qc7 6.Bd3 Nf6 7.0-0 Nc6 (or 7...d6
8.f4 Be7 9.Kh1 Nbd7 10.Qe2 0-0 11.Bd2 Nc5= Smyslov vs Kan, 1942) 8.Be3 Ne5 9.h3 Nc5 10.Kh1 d6 11.f4 Ng6 12.Qe1 0-0 13.f5 Ne5= Kasparov vs G Milos, 1996
<5...Qc7> Carlsen could have transposed in the line given above by playing 5...Nf6 6.0-0 Qc7 7.Nc3 Nc6 8.Be3 Ne5 etc...
<6.Qe2> A rare line compared with 6.Nc3 Nf6 7.0-0 Nc6 8.Be3 Ne5 9.h3 Bc5 etc. as shown previously.
<6...Nc6 7.Nxc6! dxc6 8.e5!> This appears to be somewhat of an inferior move. The main line here goes like this : 6...d6 7.0-0 (or 7.c4 Nf6 8.0-0 g6 9.Nc3 Bg7 transposing) Nf6 8.c4 g6 9.Nc3 Bg7 10.Rd1 (or 10.Nf3 0-0
11.Rd1 Nc6 12.h3 Nd7 transposing; also 10.Be3 0-0 11.Rac1 Nbd7 ⩲ V Musil vs Karpov, 1975) 0-0 11.Nf3 Nc6 12.h3 Nd7=/ ⩲ Thomas Luther (2435) - Christopher Lutz (2550), Bundesliga 92-93 (league, Germany) 1992, round 1 - Sindelfingen vs. Porz, 0-1.
<8...C5N 9.0-0> The kid seems destabilized and improvises this novelty! Here the theory knows 8...Ne7 9.0-0 Ng6 10.f4 (Axel delorme (1850) - Thimotée Heinz (2053), Under 18 France Team Championship 01-02 2002, round 5 - Sautron I vs Bischwiller I, draw) Be7 ⩲ Komodo 10 - 64 bits. After the game move, Carlsen is seriously behind in his development...
