39... Nf4
Although I can, and should've played this on move 37 rather than just repeating positions trying for tactical cheapos

 
40. Rc5+ Kd6 41. Rf5 Nd3
Now I will queen for sure

 
42. g4 e1=Q+ 43. Bxe1 Nxe1
Here I thought I'd be totally winning, but the position is still complicated. I have two extra pieces, but now White has three extra pawns and pawns increase in value during the endgame. This is hard, but two pieces should be enough to beat White's three pawns.

 
44. Kf1 Nd3
More logical than Nc2 which just puts my knight out of play and doesn't threaten a pawn.

 
45. b3 Be7
I use this single opportunity to force a rook trade, going into a simpler ending

 
46. Rxf8 Bxf8
My two pieces will definitely be enough to beat White's three pawns now.

 
47. Ke2 Ne5
White's kingside pawns will fall now. White should've kept them back.

 
48. g5 Ke6 49. h4 Bxa3 50. b4 Kf5 51. Ke3
I realized maybe winning would take more effort than I originally thought. After trading rooks, the position looked effortlessly winning for me, but now I see that while I'm eating White's kingside pawns, his king has a path to my queenside pawns. If I try defending my queenside pawns, his kingiside pawns promote.

 
51... Kg4 52. Kd4
There's no way to defend my queenside pawns against White's king

 
52... Ng6 53. Kc5 Bb2
Now I see the only way to win is to get White's last queenside pawns before eating the kingside ones, leaving me with a king, bishop and knight against just a king. I honestly didn't think I'd be able to win that ending

 
54. Kb6 Bxc3 55. Kxa6 Bxb4 56. Kxb5 Bd2 57. Kc4 Kxh4 58. Kd3 Bf4
Bxg5 looked too passive

59. Kd4 Kxg5
I never learned exactly how to force a win in this ending, which is what made me think I couldn't win here. Although even if I had never considered ever getting this ending, the win is still there, and all it takes is logical chess to win.

 
60. Ke4
Winning this is hard because a knight and bishop cannot create a solid barrier to enclose White's king. A rook can easily create a solid barrier, while so can two bishops, which is why winning those endings are a lot easier than winning this one.

 
60... Ne7
Knight and bishop are strongest when they are on the same color, because they control both colors and make somewhat of a barrier.

 
61. Kd3 Kf5
restricting the king more. All I need to do is push White's king to the same colored corner as my bishop (it's impossible to force checkmate with bishop and knight in a corner that isn't the same color as the bishop)

 
62. Kd4
White should try staying as close to the centre as possible

 
62... Bd6
Creating a stronger barrier

 
63. Kd3 Nc6
The winning process is slow, but I'm fine as long as I can do it in less than 50 moves since I took the last pawn, so that White cannot claim a draw.

 
64. Ke2 Bc5
restricting more squares

 
65. Kf3
If Kd3 then my next move still creates a barrier
