Bishop & Knight Mate

Emboldened by a blog entry and a lecture from chesslectures.com, I relearned the Bishop & Knight vs King mate.

The steps to this mate are simple:
  1. Push the enemy king to the edge of the board.
  2. Force him to the correct corner.
  3. Mate him.

You must force the enemy king into the corner that's the same color as your bishop to mate him. Mostly, you simply take away his safe squares one by one.

The scary part is, to force him into the corner, you must allow the enemy king to leave the edge of the board for a few moves, risking escape! Watch moves 8-12 carefully.

As you have seen on my chess lessons blog I have written three posts about this endgame, each dealing with one of these three steps.

There is a faster Mate for white than the one shown above. On move 8 white should:
8.Kd6 Kf7
9.Ne7 Kf6
10.Be3 Kf7
11.Bg5 Ke8
12.Ng6 Kf7
13.Ne5+ Ke8 (I have heard this position called the Lock as black is now locked in the corner with the bishop of the same color)
14.Kc7 Kf8
15.Kd7 Kg7
16.Ke7 Kg8
17.Bh6 Kh7
18.Bf8 Kg8
19.Ng4 Kh7
20.Kf7 Kh8
21.Bg7+ Kh7
