In the 1999 Manhattan Club Championship, 11-year old Hikaru Nakamura pulled off the best game of the championship and was the recipient of the Pinkus Brilliancy Prize.
White: Hikaru Nakamura vs. Black: Marian Waxman Opening: Scotch Game
1. e4 e5 2. Nf3 Nc6 3. d4 e:d4 4. N:d4 Bc5 5. Be3
Development is sharper than an exchange like 5. N:c6 Qf6! 6. Qd2 d:c6 7. Nc3 Be6.
5. … Qf6 6. c3 Nge7 7. Bc4 O-O 8. O-O Ne5?!
This exposure in the center allows my square count potency.
9. Be2 d6 10. f4 N/5-g6
This lands Black into trouble and probably best is to retreat the Knight to c6. Still, White then can create play on the Q-side, 11. b4 Bb6 12. Na3 N:d4 13. c:d4 Nc6 14. Nc2. I think White stands slightly better.
11. b4 Bb6 12. Na3 Nc6 13. Nc4 B:d4 14. c:d4 Qe7
Perhaps Black should strike the center. A bit better is: 14…d5 15. e5 Qe7 16. Nd2
15. b5! Nd8 16. f5 Nh8 17. Bd3 f6 18. Rf3 g6 19. Bh6 Re8 20. Ne3 c6 21. b:c6 b:c6 22. f:g6 h:g6 23. Rc1 Kh7 24. Bf4 Nhf7 25. Rg3
Hitting the weak g6 square.
25. … Rh8 26. Qh5!! Kg8 27. Q:g6+ Kf8 28. d5 c5 29. Qg7+ Ke8 30. Bb5+ Bd7 31. Nf5 Black resigns.
Quite an achievement for an 11-year old.
Today, Hikau reigns as a US Chess Champion.
