1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. f1b5  3... b8d7  4. a2a4 A relatively rare continuation,  which has been tested by the world champion. Another player who deserves  credit is the Dutch number one, Anish Giri. 4... e7e6  5. b1c3  5... a7a6  6. b5e2  6... b7b6 Grandelius decided to build a Hedgehog set-up. 7. d2d4  7... c5d4  8. d1d4 This is one of the ideas of White's set up. There is no  black knight ready to torture the queen. 8... c8b7  9. e1g1  9... g8f6  10. f1d1  10... f8e7 Grandelius simply finishes the  development. 11. c1e3  11... e8g8  12. e4e5 Adams would not miss a chance like this. 12... b7f3  13. e5d6  13... f3e2  14. c3e2  14... f6d5  15. d6e7  15... d8e7  16. e2c3  16... d5e3  17. d4e3 As a result of the forcing sequence White got the slightly  better chances. The queenside majority secures Adams long-lasting  advantage. 17... f8d8  18. c3d5  18... e7f8 Grandelius correctly sacrifices a pawn. 19. d5b6  19... d7b6  20. e3b6  20... d8b8  21. b6d4  21... b8b4  22. d4e5 Forcing some weaknesses. 22... f8c8  23. d1d2  23... f7f6  24. e5e2  24... b4b2  25. a1d1  25... g8h8  26. h2h3  26... h7h6  27. d2d6 The white pieces dominate. Now the plan is to force  the opponent into passive defence. 27... a8b8  28. d1d2  28... b2b6  29. d6d7  29... b6b7  30. d7d6  30... b7b6  31. c2c4  31... b6d6  32. d2d6  32... e6e5  33. e2e4  33... a6a5  34. d6d5  34... c8c7 The goal has been achieved, Black is forced into  passive defence. Now by combining the threats against the black king Adams slowly pushes his pawn forward. He would often use small tactics to  achieve the desired set-ups. 35. g2g3
