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
