{ In the match with Slovakia team we considered to win with big score and their avoiding the fight on white boards couldn't please us. So all responsibility was laid on Alexander Morozevich and me, who were playing with the white pieces. Sasha gradually outplayed Shtol and reached the victory and I have played rather balanced game. } 1. d4 Nf6 2. c4 g6 3. g3 { It seemed to me the variation used to play by my opponent against system with g3 is rather doubious. That's why I chose this move. Nevertheless it was not so easy way indeed. } 3... Bg7 4. Bg2 O-O 5. Nc3 d6 6. Nf3 Bg4 7. h3 Bxf3 8. Bxf3 Nc6 9. e3 Nd7 10.

White keeps a couple of pieces, consolidates plentifully the f2 square, clears the 3rd rank for the Rook (subsequently not for Rb1-b3 but Rh1-h3-a3!), and also threating 19.ef5 gf5 20.g4 and then it will be able to put the knight into the play through the e3 square. } ( 18.
