Nc3 d5 3. d4 Nf6 4. cxd5 exd5 5. Bg5 {More and more people are adding this Classical set up against the Queen's Gambit in their Repertoire. Only a decade ago, allowing the exchange Queen's Gambit was basically extinct.} c6 6. e3 h6 (6... Bf5 7. Qf3 Bg6 8. Bxf6 Qxf6 9. Qxf6 gxf6 {has shown to be very solid for Black.}) 7. Bh4 Be7 8. Qc2 Nbd7 9. Bd3 Nh5 {most of the people playing this system with Black are now depending on some sort of early Nh5 to try to equalize. Black will castle in the same side that White does.} 10. Bxe7 Qxe7 11. Nge2 Nb6 12. O-O O-O 13. Rae1 Be6 14. Nc1 Rad8 15. Nb3 Rfe8 16. Nc5 { At the end of the day it still seems that White's position is slightly preferable, but Black remains extremely solid and his pieces are all developed. } Bc8 17. b4 Nc4 $1 {This move requires some calculation, despite the apparent simplicity of it.} 18. Qe2 Qg5 19. f4 $6 {Overly ambitious.} (19. Bxc4 dxc4 20. Qxc4 Bh3 $15) 19... Qh4 20. Bxc4 dxc4 21. g3 $2 {Allowing a rather obvious "sacrifice".} (21. Qxc4 Nxf4 $1 {and because of the multiple pins and hanging rooks, White simply can't take this intruding knight. Black stands slightly better due to his pawn structure.}) 21... Nxg3 22. hxg3 Qxg3+ 23. Kh1 (23. Qg2 Rxe3 24. N5e4 Qxg2+ 25. Kxg2 Bh3+ 26. Kh2 Rd3 {gives Black at least three pawns for a knight, which is enough material. Combined with the superior activity and the potential passed pawns in the endgame, Black is almost winning.}) 23... Qh3+ 24. Qh2 (24. Kg1 Rd6 {is rook lift 101.}) 24... Rxe3 25. Nd1 Rxe1 26. Qxh3 Bxh3 27. Rxe1 b6 28. Ne4 Rxd4 {Four pawns. Black has more material and the better position. White's knights lack good squares.} 29. Kh2 Bf5 30. Ndc3 Rd3 31. b5 {Desperation.} cxb5 32. Nxb5 Bd7 33. a4 a6 34. Nc7 Bxa4 35. Nxa6 c3 36. Nb4 Rd4 {White loses a piece, and after that he is down too many pawns.} 37. Na2 Rd2+ 0-1

Bxf6 gxf6 {To me it is unclear what Raport has for his pawn. Yes, Black's pawn structure on the kingside is crippled, but it controls the important e5 square. Black also has the pair of bishops and a future break on c5 or e5. White's development advantage and central control is not amazing enough to compensate for a pawn. Black should already be better.} 9. g3 Bb7 10. Bg2 Nd7 11. O-O a5 12. b3 cxb3 13. Nxb3 bxa4 14. Rxa4 Ba6 15. Ra2 Bb5 16. Rfa1 O-O 17. Nc1 Rc8 18.

Qxd3 c5 20. dxc5 (20. d5 Nb6 21. dxe6 fxe6 $17) 20... Nxc5 21. Qe3 Kg7 {Black is by no means winning, but with his extra pawn, he is clearly in the driver's seat.} 22. h4 Qd6 23. Rc1 Nd7 24.
