1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. f2f3 [%cal df2f3][%c_arrow f2f3;keyPressed;none;from;f2;opacity;0.8;to;f3;persistent;false] A move that is played with the intention of avoiding the Grunfeld Defense and which leads to very interesting and complicated positions, making it a great choice for aggressive players. 3... d7d5  4. c4d5  4... f6d5  5. e2e4  5... d5b6  6. b1c3  6... f8g7  7. c1e3  7... e8g8  8. d1d2  8... b8c6  9. e1c1 This is a critical position for the 3.f3 system. Black has three major moves: 9...f5, 9...Qd6 and 9...e5. 9... d8d6 This was played by Vachier-Lagrave in December, so it was reasonable to expect he would play it again. 10. c1b1  10... a7a6 Not the main move, but it has been tried by Svidler and in some correspondence games. The idea is to prevent the knight moving to b5. 11. d4d5  11... c6a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] A new move. 12. e3d4 Exchanging bishops is a smart strategy for White, as the g7-bishop is very dangerous, pointing at the white king. 12... e7e5 The problem with this move is that it closes the diagonal, but Black has a good position anyway. 13. d4f2  13... a5c4  14. d2c2  14... g7h6 [%c_effect h6;square;h6;type;Interesting;persistent;true] Looking for a more active diagonal for the bishop. 15. f1c4
