1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3  4... e8g8  5. f1d3  5... d7d5  6. g1f3 The old main move. 6.cxd5 and 6.a3 are very popular now. 6... d5c4 This move-order prevents White from capturing on d5 first. 7. d3c4  7... c7c5  8. e1g1  8... b8c6  9. a2a3  9... b4a5  10. c4d3  10... h7h6 Black plays a useful waiting move before deciding whether to take on d4. 11. h2h3 White decides to play a useful waiting move. 11... f8e8 A new move. 12. d4c5 Nisipeanu decides to force matters. He could keep the central tension with a move like 12... a5c3  13. b2c3  13... d8a5 This is not the best, but the position is still fine. 14. d1c2  14... a5c5  15. a3a4 A typical move, preparing to play Ba3. 15... c6a5 The first real mistake. Black is in trouble after this move. Let's remember again that \"a knight on the rim is dim.\" 16. c1a3  16... c5c7  17. f1d1 Now White has the bishop's pair and better development. 17... a5c4  18. d3c4  18... c7c4  19. d1d4  19... c4a6  20. f3e5 Now the c8-bishop is completely out of play. The presence of opposite colored bishops increases the strength of the attack.
