1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. d2d3  5... d7d6  6. c2c3  6... g7g6  7. e1g1  7... f8g7  8. f1e1  8... e8g8  9. b1d2  9... f8e8  10. d2f1  10... b7b5 The alternative is 10...h6 and it seems as it pushes to become the main line. 11. a4c2  11... a6a5 Grandelius gains space on the queenside, thus limiting the opponent's light-squared bishop. [#] 12. c1g5 A logical novelty that fights for the d5-spot. 12... h7h6  13. g5h4  13... a5a4  14. f1e3  14... c8b7  15. c3c4 This is the major problem with the early a-pawn advance. The b5-pawn lacks defends and Van Foresst initiates complications. 15... c6b4 Grandelius on his turn decided to sacrifice a pawn. 16. c4b5  16... d8d7  17. h4f6  17... g7f6  18. c2a4  18... b4d3 That is the point: Black is grabbing a central pawn. 19. d1d3  19... a8a4 And Grandelius achieves an interesting Benko-style compensation. A couple of more useful moves and he may even take over the initiative on the queenside. 20. e3d1 Therefore, Van Foreest solidifies his queenside. In the process, however, he loses control of the center, at least for a moment. 20... a4b4  21. a2a4  21... d6d5 And Black grabs his chance. The pawns get into motion and the powerful bishops start to reveal their strength. 22. d3d2  22... d7d6  23. e4d5  23... e5e4 An obvious move, but certainly not the only way. 24. d2h6  24... d6f8 Grandelius sensibly decided not to test the queen and knights' might. 25. h6f8
