1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... d7d5  4. b1c3  4... f8e7 Unsurprising choice by Nakamura  who obviously feels very safe in the Queen's Gambit. 5. c1f4  5... e8g8  6. e2e3  6... b8d7  7. c4c5  7... c7c6  8. h2h3  8... b7b6  9. b2b4  9... a7a5  10. a2a3  10... h7h6  11. f1d3  11... c8a6  12. e1g1  12... d8c8  13. c3a4  13... c8b7 Basically, winning a valuable tempo. 14. d1c2  14... a6d3  15. c2d3  15... f6e4 With the extra pressure against the c5 pawn  White cannot push b4-b5 that easily. 16. f1b1  16... a5b4  17. a3b4  17... b6b5  18. a4c3  18... f7f5 Now it is a Stonewall set-up, without the usually poor light-squared  bishop for Black, but with an open a-file which favors White. 19. c3e2 The beginnig of a nice maneuver. 19... e7f6 From here on  Nakamura wishes for one thing only- the e6-e5 break. On the queenside it  is like a game of a "blink." Whoever blinks first gives something along  the a-file.
