Stoofvlees played with the black pieces against Ginkgo. Black sacrificed a pawn in the middle game for some attacking initiative. Black then shifted from the attack to taking two pawns on the other side of the board, gaining an outside protected passer in the process. While tying the white pieces with the passed pawn, black shifted the emphasis one more time from one side to another, gaining second outside passer. With a rook and knight against rook and bishop, white did not stand a chance of stopping outside passers at both sides of the board.

Black has sacrificed the pawn on d6 for activity. Pawn to b4 will open white's king for an attack.
|Position after 30... Bc3|
18... b4 19. axb4 Bxb4 20. Rf1 Na5 21. Na4 Qb7 22. Nxa5 Bxa5 23. b3 Bb4 24. Qd3 Qc7 25. Qg3 e5 26. Nb2 Be6 27. Bc4 Rfc8 28. Qd3 Bxc4 29. Qxc4 Qe7 30. Qd3 Bc3
Black is threatening Qa6 with mating intentions. To prevent the threat, 31. Qd6 is practically forced. Black's queen is on a flexible square, ready to switch from the queenside attack to targeting the kingside pawns.
|Position after 38. gxf3|
31. Qd6 Qh4 32. f4 Qxh2 33. Qd3 exf4 34. Nc4 Qg3 35. Kc1 Bf6 36. e5 Bg5 37. Qf3 Qxf3 38. gxf3
In just a few moves, black was able to get from being pawn down to pawn up with significantly better pawns. After the queen exchange, black has a protected outside passed pawn on h6 with big potential. Black is now significantly better if not objectively winning.
|Position after 54... Be7|
38... Be7 39. Rd7 Kf8 40. Re1 h5 41. Rh1 g6 42. Rd4 Rd8 43. Re4 Kg7 44. Kb2 f5 45. exf6+ Bxf6+ 46. Kc1 Rb5 47. Rd1 Rxd1+ 48. Kxd1 h4 49. Re2 Rg5 50. Rh2 Rg1+ 51. Kd2 g5 52. Nd6 a5 53. Ke2 Kg6 54. Ne4 Be7
In this endgame, the black bishop is a superior piece to the white knight. This is because the bishop is able to support play on both sides of the board, whereas the knight being slower has to choose the side. Black is able to take advantage of this and will soon win the b3 pawn and the game. White has no chance of stopping outside passers on both a and h files.
55. c3 Kf5 56. Nf2 Rb1 57. Kd3 Rxb3 58. Rh1 a4 59. Kc2 Rb6 60. Re1 Re6 61. Ne4 g4 62. fxg4+ Kxg4 63. Nf2+ Kf5 64. Rf1 Bc5 65. Nd3 Be3 66. c4 h3 67. Kb2 Rh6 68. c5 Ke4 69. Nb4 Bxc5 70. Kc3 Bxb4+ 71. Kxb4 h2 72. Re1+ Kf3 73. Rh1 Kg2 74. Ra1 h1=Q 75. Rxh1 0-1
The game was adjudicated as 6-men tablebase win for black.
