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.
