1. d4 d5 2. Nf3 Nf6 3. c4 c6 4. Nc3 e6 5. cxd5 From Slav Opening, White choose to transpose into The Exchange Variation of The Queen Gambit Decline Variation.
5...exd5 6. Bg5 Nbd7 7. e3 Bd6
8. Bd3 Nf8 9. Bh4 Ng6 10. Bg3 O-O 11. Qc2 Re8 12.O-O Bxg3 13. hxg3 Qe7 14. Rab1 White prepare to push b5 and start the Minority attack which is a typical idea in The Queen Gambit Decline :Exchange Variation.
14...Ne4 15. Bxe4 dxe4 16. Nd2 Bf5 17. b4 White start the typical minority attack on the queenside but black answer with not so typical attack with
20. Ne2 Probably Megaranto doesn't want black become to active with 20. gxh4 Nxh4
20...Bg4 21. Rfe1 Bxe2 22. Rxe2 hxg3 23. fxg3 Now white's pawn structure is weaken. (e3 and g3 is a potential target)
23...Rac8 24. Rc1 c5! Black sacrifice a pawn for initiative.
25. dxc5 Ne5 26. Nxe4 Nd7 27. Nf2 I think 27. c6!? is an interesting alternative. It involved an exchange sacrifice where white sac his queen for two rooks. 27...Qxe4 28.cxd7 Rxc2 29.dxe8+=Q Qxe8 30.Rcxc2 with a double edge game.
27... Rxc5 28. Qd2 Nf6 29. e4 Rxc1+ 30.Qxc1 Qe5 31. g4 Qd4 Increasing the presing Nxg4 next - winning a pawn.
32.Qe3 Qa1+ 33. Kh2? White should have play 33.Re1Qxa2 34.g5 with some counter playsure on the isolated pawn on e4 by pinning white's knight and threaten.
33...Rxe4 34. Qxe4 Probably Megaranto has just realized that taking the knight with 33.Nxe4 is not possible because of 33...Ng4+ forking white's king and queen White will lost more material if he choose to keep the queen for e.g 34.Qf3 Qe5+ and white will lose the Rook on e2.
34...Nxe4 35. Nxe4 Qe5+ 36. Ng3 Qf6 36... Qg5! simply win white's g pawn .
37... Qh6+ 38. Nh5 g6 Now white will lost a piece.
39. Re8+ Kh7 40. Re7 gxh5 41. Rxf7+ Kg6 42. g5 Qxg5 43. Rf3 Qg4+ 44. Kh2 Qh4+ 45. Rh3 Qf4+ 46. Kh1 a5 47. a3 Qc1+ 48. Kh2 Kg5 49. Rf3 Kg4 50. Rh3 a4 51. Rf3 Qd1 52. Rc3 Qd6+
