53... Ne5
At this point my next goal is to eliminate the pawns first.

 
54. g5+ Ke6 55. h5 Nd7 56. g6 Kf6 57. Kg4 Ne5+ 58. Kf4 Bf5 59. g7 Bh7 60. h6
It got pretty hairy as those pawns got pretty close to queening, but it was really a formality. It was going to happen one way or another. However, don't think that I didn't spend hours thinking carefully through each move making sure I don't make a mistake.

 
60... Nf7 61. g8=Q Bxg8 62. Ke4 Nxh6
And finally, here we are. I asked berbatov here to play till the end as I planned to annotate this ending. He graciously obliged. He himself was curious how to finish this as he wasn't sure it can be done either.

Basically, idea has to do with something called DELETANG TRIANGLES. You use the ideas of these triangle to get a sense of a board control and a King control with these 3 black pieces. I recommend you look it up.

However, the first goal is to take over the center of the board. Take over the e,d, 4,5 central square and then work from there.

 
64. Ke4 Bh7+ 65. Kf4 Ne5 66. Ke3 Nc6 67. Kf4 Ke6 68. Kf3 Ke5
My King has finally arrived at the central 4 square area.

Now try to corner with the King. The Bishop and Knight are serving as a support. As a white you should stay away from a lower rings (lowest ring being h8-a8-a1-h1, the second one would be g7-b7-b2-g2, etc). Berbatov doesn't seem to care so much about making my job harder so at times he drops the to the lower ring without being forced to.

72. Kf2 Bg4 73. Ke1
The moment he drops the ring, I try to keep him at that ring.

73... Ke3
So my King goes a lower level trying to pin him at the lowest ring.

 
74. Kf1 Bh3+ 75. Kg1 Kf3
Note it is essential that once you get the King on the lowest ring you are to push him into a corner with the color of your bishop. My bishop is a light bishop, so that the only corner I can mate him is the white corner.

76. Kh2 Bf5 77. Kh1 Nd3 78. Kh2 Nf4 79. Kg1 Bd3 80. Kh1 Kg3
Remember this position. It is essential to end in this position because any other one can easily force a stalemate. The way I tried to remember it, is I visualized his King in the corner, my King right above him but to the side, the knight "touching diagonally" my King. The bishop is used to time his King into that corner accordingly as to deliver the final blow. You'll see now what I mean:

81. Kg1 Nh3+
His king can move to only 1 spot: Kh1.

 
82. Kh1 Be4#
The end. I tried to explain as much as I can, but still I encourage you to do some researching of your own as I don't think my explanation is adequate to get this procedure fully down. It actually takes some practice, and I am sure I could have explained a bit more what roles Bishop and Knight play.... Lets leave that as a homework :)
