Lasker, Emanuel VS Burn, Amos 1909.03.04

Annotations

1. 13.Ne3 Intending to operate in the centre. Kt - Q 5 threatens to embarrass Black, as the Knight cannot be taken because of the loss of the K P, and on the other hand, the Knight would exert great pressure on the Black position.
2. 13…Bg4 Parrying the threat indirectly. But the move allows two Bishops, which command the whole board.
3. 22.d5 Bowing to necessity; as Black was preparing P - Q 4. But the blocking of the Pawns is unfavorable for the Bishops.
4. 30.Ne1 Kt - R 4 looks better than it is. Black takes, and White has afterwards no sufficient material to compel the exchange of Pawns.
5. 34.Rf2 Intending to play eventually Kt - K 3, but be ready with P - K B 4 against B - Kt 4.
6. 34…Nc8 To prevent the White Knight from taking possession of K B 5 (Kt - K 3, Kt - K 2).
7. 45…f6 Black can no longer get rid of White's Knight by Kt - K 2, which he seems to have overlooked when playing his 43rd move.
8. 52.Bc6 Threatening now P - Q Kt 4.
9. 57…Ng4 If 57) .... Kt x R P, White plays K - R 2 and the Knight is in a very bad position.
