White: Teichmann. Black: Amateurs in consultation.
Two Knights’ Defence.
1. P-K4 P-K4 2. Kt-KB3 Kt-QB3 3. B-B4 Kt-B3 4. Castles
Diag. 111
The idea underlying this pawn sacrifice is to open the K file for the Rook. It will be seen that, with correct play, Black manages to castle just in time, and White, though winning back his pawn, has no advantage in position. The opening is seldom played by modern masters.
Instead of the move in the text, White can hardly defend the KP with Kt-B3, as Black simply captures the pawn and recovers his piece by P-Q4, with a satisfactory position. It is even better for Black if White plays 6. BxPch in reply to 5. … KtxP. The capture of White’s KP is far more important than that of the Black KBP, particularly as the White Bishop, which could be dangerous on the diagonal QR2-KKt8, is exchanged, e.g. 6. … KxB; 7. KtxKt, P-Q4; 8. Kt-Kt5ch, K-Kt1! Black continues P-KR3, K-R2, R-B1 and has open lines for Rooks and Bishops.
