context: 1. e2e4  1... e7e6  2. d2d4  2... d7d5  3. e4e5  3... c7c5  4. c2c3  4... b8c6  5. g1f3  5... d8b6  6. a2a4 A surprising move early in the game. This isn't listed even in the top five choices of the computer, and it's only the ninth most played move. From what I know, it was never tried by a GM before, so it's a really new concept. To be honest, the move seems quite strange—what's the idea $2 In some lines a4-a5 or Bb5 can be tried, but it seems that after the exchange on d4, the weakened b4-square should give Black good play. Perhaps the greatest merit is forcing the opponent into an unknown position right on move six. 6... c5d4 Definitely the most natural reply, since the b4-square can be used by Black's pieces. 7. c3d4  7... g8h6 This isn't the best way to get the knight to f5, since it allows White the interesting option of capturing it. 8. f1b5  8... h6f5  9. b1c3  9... c8d7  10. e1g1 This is a normal French position, but the pawn on a4 and the bishop bring fresh nuances. For instance, now White is not worried about the capture on d4, as after this Black's king would remain in the middle of the board. 10... a7a6  11. b5c6  11... d7c6 Taking with the queen is also possible. 12. c3e2 Here the pawn on a4 is quite useful, since the bishop cannot go to b5. It turns out that Black is in some danger in this position. Apart from the lack of development and the king in the center, there's a problem with the knight on f5, which isn't very stable. Black should always watch out for g2-g4. White's last move is very accurate, since he waits for the bishop to go to e7 before seriously considering g2-g4. Meanwhile, the knight's position is improved, since it can go to f4 and later h5 or d3. 12... f8e7  13. b2b3 Another subtle move. The path of the bishop is open to a3, and this will be quite useful. 13... e8c8 The king goes to the wrong side of the board. More than anything, this is a positional mistake: White's attack is simply much faster. 14. c1d2 The human reaction, simply preparing b4-b5 and mate. 14... c8b8 After castling queenside, Kb8 is the first move that should be considered. 15. b3b4
