Nf3 Nf6 3. Nc3 Nc6 4. d4 cxd4 5. Nxd4 e6 6. a3 (6. g3 {is the main line and probably the most ambitious continuation but Vladimir always tries to avoid theoretical battles aiming for stable positions where his positional skills will tell.}) 6... Bc5 ({I would prefer to play} 6... Be7 {because if White continues in the same manner as in a game} 7. e4 O-O 8. Be3 {Black has a strong reply} ({also} 8. Be2 {could be well met by} d5 9. exd5 exd5 10. O-O Nxd4 11. Qxd4 Be6 {=}) ({for taking control over d5 square White has to waste a tempo for} 8. Nf3 {and after} Qc7 9. Be2 b6 10. O-O Bb7 {Black gets a nice Hedgehog setup}) ({or} 8. Nb3 {when Black is a clear tempo ahead comparing to the game}) (8. Nxc6 dxc6 9. Bf4 Nd7 {also good for Black}) 8... d5 {! equalising.}) 7. Nb3 Be7 8. e4 d6 9. Be3 O-O 10. Be2 b6 11. O-O Bb7 {Players reached the standart Hedgehog position with some White's advantage.} 12. Nd4 { ?! This innacuracy allows Black to get an ideal setup. Actually Nc6 could be better placed on d7 because on c6 it interferes both Bb7 and eventual Rc8.} ({ The only active path for this Knight is via e5 and therefore} 12. f4 {! which stops this maneuvre was the strongest move:} Rc8 13. Qe1 {!?} ({or} 13. Rc1 Nb8 14. Bd3 Nbd7 15. Qe2 $14) 13... Nb8 14. Nd2 $14 {keeps the tension.}) 12... Nxd4 ({Now when Black can't capture on c6 with a pawn} 12... d5 {? does not work:} 13. Nxc6 Bxc6 14. exd5 exd5 15. Bf3 {wins a pawn for White.}) ({In my opinion there was no need to rush with Knights' exchange:} 12... Rc8 13. Nxc6 ( 13. Qd2 {?} Na5 $17 {!}) 13... Bxc6 14. f3 Qc7 {with normal position. But 12... Nxd4 is OK too.}) 13. Qxd4 Qc7 14. Rac1 Rfd8 15. b4 Rac8 16. f3 Qb8 17. Rfd1 { Both sides made all standart development moves and Black is very well prepared to thematic strike in the center which leads to complete equality.} d5 {!} 18. cxd5 (18. exd5 exd5 19.
