1. d2d4  1... d7d5  2. c2c4  2... c7c6  3. g1f3  3... g8f6  4. e2e3  4... e7e6  5. f1d3  5... b8d7  6. b1c3  6... f8d6 This is a not very popular variation of the Semi-Slav Defense. 7. e1g1  7... e8g8  8. e3e4  8... d5e4 It's difficult to say which pawn Black should capture. The move played is a little passive. 9. c3e4  9... f6e4  10. d3e4  10... d7f6  11. e4c2  11... c6c5  12. d4c5 This is not the most dangerous move for Black. There are two very promising alternatives. 12... d6c5  13. d1e2  13... h7h6 Too slow. It's best to start queenside development right away. 14. c1f4  14... b7b6  15. a1d1  15... d8e7  16. f3e5  16... c8b7  17. d1d3 Only this is a new move. Opening theory is really far advanced in some variations. This move is very natural, taking the rook to the attack. 17... b7e4  18. d3h3
