65... Ne5+
The knight and bishop have the strongest barrier when they are two horizontal squares away from each other, or two vertical squares.

 
66. Kg3 Ng6
I considered Be3 also, but this way looked faster. Looking back, maybe Be3 was correct

67. Kf3 Nf4
After each move, my barrier keeps getting tighter and White's king has less squares

 
68. Kg3
forced

 
68... Ke4
White can hold on a little longer if he plays Kg4, staying closer to the center, and play could continue Ne2 Kg5 Be7 Kg6 Ke5 Kf7 Kd6 Kg6 Ke6 Kh5 Kf5 and White's king is cut off and trapped toward the corner.

69. Kh2
Instead, White knows he cannot get mated in a light corner, so tries to get as far away from a dark corner as possible.

 
69... Kf3
Even though White's king is in the wrong corner, it's still more restricted than it would be in the centre, so it shouldn't be too hard to force the king into the correct corner of the board

 
70. Kh1 Ne2
preparing to control h1

 
71. Kh2 Ng3 72. Kh3 Bg1
The necessary restricting move in pushing White's king toward his doom on h8.

 
73. Kh4 Ne4
restricting the g5 escape square. Every move must be accurate, or White escapes and goes to the 50-move rule. I took the last pawn on move 59, so White can claim a draw if the game reaches his 110th move.

74. Kh5
If White plays Kh3, I easily corral his king with Ng5 Kh4 Kf4 where White's king is forced to h5 anyway, but my pieces are a little closer than they are now.

 
74... Kf4
My king is my strongest attacking piece for trying to corral White's king by restricting squares around it, eventually forcing it to h8.

 
75. Kg6
Trying to get back to the centre

 
75... Ng5
This is an important move to remember, because the knight controls possible escaping squares, like after Kf6, then Bc5 solidifies the barrier and White cannot escape.

 
76. Kg7 Bc5 77. Kf6 Bf8
Now that I have the White king where I want him, I just need to make a waste move with my bishop to force the king off its square, so that I can control that square once the king is off, making the barrier tighter.

 
78. Kg6 Be7 79. Kh5 Ne6
I need to move my knight to prevent Kh4, and my knight needs to get to a square where it controls f7 and makes the barrier tighter

 
80. Kg6 Nd8 81. Kh5
There's nothing White can do to escape. The next moves are simple restricting moves that tighten the barrier

 
81... Kf5 82. Kh6 Ne6
The next step to corralling White's king to h8 is to control f8 with the knight to stop the king from escaping once I get my bishop to g5 to restrict h6, and my king to f6, the White king will be limited to three squares in the corner.

 
83. Kh5 Bd8
I need to make a waste move with my bishop in order to get White off h5, so that I can control h5 with Bg5 , taking away another square.

 
84. Kh6 Bg5+
White's king is forced toward the corner because of Kh5 Nf4#
