Annotations based on discussions with IM Oladapo Adu: There is a pretext to this game. Adu defeated Lugo only a month earlier at the Chicago Open. In that game, he played the black pieces and won convincingly. Thus, Lugo was looking to even the score.

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. Qe2

The Wormald (Alapin) Attack! 5... Bc5!? This fits Lugo's aggressive style. Adu mentions that GM Victor Mikhalevski played this against him in the Chicago Open a month earlier. That game was drawn. 5... b5 6. Bb3 Be7 7. d4 d6 8. c3 Bg4 is the Grunfeld Variation. 6. c3 b5 7. Bb3 O-O 8. O-O d5 9. d3 d4 Adu felt that Lugo was trying to close the center, but Lugo is more of an attacking player and probably wanted to close off the queenside to initiate his kingside attack. 10. Bg5 Be6 10... Qd6 11. Nbd2 Bg4 12. h3 Bh5 13. g4 Bg6 and black has equalized. 11. Bxe6 fxe6 12. a4 Rb8 13. axb5 axb5 14. Rc1 Qe8?! At this point, Adu felt the idea sacking the c7-pawn for a king side attack was a dubious idea. 15. cxd4 Nxd4 16. Nxd4 Bxd4 17. Rxc7 Nd5?!

Consistent with his previous plans, but perhaps a bit overambitious. Adu's feeling is that such a sacrifice of three pieces for a queen could not be good because the white rook has already penetrated to the 7th and the b8-rook would always be tied down to the back rank. 18. exd5 Rxf2 19. Qxf2 Bxf2+ 20. Kxf2 Qg6 21. Be7! Preventing the rook from entering the game. 21... Qxd3 22. Nc3 Stephen Muhammad suggested 22. d6!? but after 22... Qd4+ 23. Kf1 (23. Kg3 Qf4+ 24. Kh3 g5 25. g3 Qf1+ 26. Kg4 Qf5+ 27. Kh5 Kh8!) 23... Qd1+ 24. Kf2 Qd4+ the king cannot escape checks. 22... exd5 23. Bd6 d4 24. Nd5 e4 25. h3! "Making luft" in preparation of Kg1-h2. 25... e3+ 26. Kg1 e2 27. Kh2 Re8 28. Raa7! e1=Q

This game has a precedent. Adu played the black side of an interesting game at the 1998 Elista Olympiad against Belgium's Rudolph Meessen. In that game Adu allowed Messeen to have two queens roaming the board, but his minor pieces had a vicious attack on the king that won the day. Is this deja vu? 29. Rxg7+ Kh8 30. Nf6 Qee4! After 28.Raa7, Adu stated that he saw up until this point. With so many heavy pieces on the board, variations becoming mind-boggling. 31. Nxe8 Qxe8 Lugo was in serious time pressure here and knew that it would be hard to win such a game with best play. 32. Rg5 threatening 33.Be5+ 32... Qdg6 33. Be5+ Qxe5+?? 33... Kg8! keeps black in the game. Perhaps Lugo was too intent on leveling the score. 34. Rxe5 Qd6 35. Rae7 Once the d-pawn is lost then the game swings into white's favor! 35... d3 36. R7e6 Qd4 37. Re4 Qd5 38. R4e5 Qd4 39. Re4

Here Adu offers a draw by three-fold repetition, but... 39... Qc5? 40. Re8+ Kg7 41. R4e7+ Kf6 42. Rd7 Now the pawn dies and the rooks are free attack the exposed king. 42... Qb4 43. Rxd3 Qxb2 44. Rf3+ Kg7 45. Re7+ Kg6 46. h4 More help is on the way. 46... h6 47. Re6+ Kg7 48. h5 Qd2 This move allows white to win quickly. 48... Qd4 49. Rg6+ Kh7 50. Rf7+ Kh8 51. Rxh6+ Kg8 52. Rf3 Qh4+ allows black to fight a bit. 49. Rg6+ Kh7 50. Rf7+ Kh8 51. Rgf6 Qd5 52. Rxh6+ Kg8 53. Rff6 Qe5+ 54. Kh3 Qc7 55. Rf3 Qe5 56. Rg6+ Kh7 57. Rg4 Qe6 58. Rff4 Qe3+ 59. Rf3 Qe6 60. Kg3 Qe1+ 61. Kh2 Qe5+ 62. Rgf4 Kh6 63. g4 b4 64. Kh3 b3 65. Rf7
