dxc4 9. Bxc4 a6 10. Ng5 {A rare continuation of Russian GM Vadim Zvjaginsev.
10.Rd1 and 10.a4 are more usual moves.} h6 ({If Black accepts the sacrificed
pawn} 10... Bxh2+ 11. Kxh2 Ng4+ 12. Kg1 Qxg5 {then after} 13. f3 Ngf6 14. e4 {
White has more than enough compensation (strong pawn center, two bishops,
development advantage).}) 11. Nge4 Nxe4 $6 ({After the correct} 11... Be7 12.

b5 $6 ({This standard Slav Defence move does not work here, because Black will
not be able to play c6-c5, which means that White will fix the c6 pawn and
Black's c8 bishop is going to be very passive. Black should have tried} 13...

probably decisive mistake. Correct was} 15... a5 16. a3 f5 17. Nc5 Nxc5 18.

White is slightly better.}) 16. Nc5 $1 Nxc5 17. Bb4 $3 {An excellent move,
which is possible due to Black's 15...f5? From now on White will have a huge
positional advantage.} Bd7 18. Bxc5 Qd8 19. Rac1 {Black has a strategically
lost position. There are holes on e5 and c5, the d7 Bishop is paralyzed
defending two backward pawns on e6 and c6. White has a clear plan to increase
his advantage: 1) exchange the dark-squared bishops 2) occupy or control the
central dark squares (c5, d6, e5); 3) pressure c6; 4) when all Black's pieces
are tied down to the defense of the c6 weakness, White should exchange the
queens, then open the kingside to create a second weakness and activate the
king.} a5 20. Bf3 Rc8 21. Qd2 a4 ({Or} 21... b4 22. a3 bxa3 23. bxa3) 22. g3 $1
