As the R holds the RP, e.g. K-R4; 43. B-B4 followed by R-R6ch or 42. … K-R2; 43. R-R8, etc.
GAME No. 41
White: Niemzowitsch. Black: Tarrasch.
Queen’s Gambit Declined.
1. P-Q4 P-Q4
2. Kt-KB3 P-QB4
3. P-B4 P-K3
4. P-K3 Kt-KB3
5. B-Q3 Kt-B3
6. Castles B-Q3
7. P-QKt3 Castles
8. B-Kt2 P-QKt3
9. QKt-Q2 B-Kt2
10. R-B1 Q-K2
11. PxQP
The most natural move to which the development of the QKt at Q2 instead of B3 would seem to lead is Kt-K5 followed by P-B4. After 11. Kt-K5 Black could not yet attempt 11. … PxQP; 12. KPxP, B- R6, weakening the QP, because of 13. BxB, QxB; 14. PxP, KtxKt; 15. PxKt, KtxP; 16. Kt-B4 and Kt-Q6.
11. … KPxP 12. Kt-R4
In order to provoke Black’s weakening move: P-Kt3, which might give White chances of attack on the long diagonal QR1-KR8, White gives up two clear moves. Black is able to get considerably ahead in his development, much to White’s disadvantage.
12. … P-Kt3
13. KKt-B3 QR-Q sq
Not Kt-K5 yet, on account of 14. PxP, PxP?; 15. BxKt, PxB; 16. KtxP.
