1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c1f4 The London system is a fearsome weapon in the  hands of the Vietnamise GM. 3... e7e6  4. e2e3  4... f8d6  5. b1d2  5... c7c5 And Caruana  cannot complain of practice in the line as well. In this game he decided  to choose something more complex. 6. c2c3  6... e8g8  7. f4g3  7... b7b6 The same idea to swap off his problematic bishop,  borrowed by the French defense. 8. f1d3  8... c8a6  9. d3a6  9... b8a6  10. d1e2  10... a6b8 The  knight has done it's job and is now moving towards the optimal square.  10...Nb8 scores better than 10...Nc7 and which should not be surpsing as  it is left far away from the central squares. 11. f3e5  11... d8c7  12. e1g1  12... b8c6  13. f2f4 The pawn skeleton has been changed into a reversed Stonewall, where  Le is happy with the aggressive position of his bishop, whereas Caruana  managed to completely get rid of his weak one. 13... c6e7
