Diag. 106

If now White plays P-Q4, he loses a piece by PxP; 24.  KtxP?, RxR; 25.  KxR, Q-B3ch.

23.  R-K1

The Rook has no future here, and R-Q1, in order to play P-Q4, is more logical.  But as Black obviously threatens to double his Rooks on the KB file, it would be advisable to play for an exchange of Rooks, with:  Kt-Kt2, QR-B1 and Kt-K1.

23. ...  R-B2 24.  QR-K2 QR-KB1 25.  Kt-K1 Kt-Q5 26.  R-Q2 Q-Kt4 27.  Kt(K3)-Kt2 BxKt 28.  KxB

KtxB is frustrated by Kt-B6ch.

28. ...  Q-K6

All the Black forces are now in action, and White has no defence, as his pieces can hardly move.

29.  K-B1 Kt-Kt6! 
Resigns.

If R-K2 or B2, there follows RxRch; 31.  RxR, Kt-Q7ch; 32.  QxKt, QxQ.

Game no. 7

White:  Marshall.  Black:  Tarrasch.

Max Lange Attack.

1.  P-K4 P-K4 2.  P-Q4 PxP 3.  Kt-KB3 Kt-QB3 4.  B-QB4 B-B4 5.  Castles Kt-B3

Black can avoid the complications of the Max Lange attack by 5. ...  P-Q3.  In that case White cannot recover the pawn, and in order to develop his QKt effectively, would have to play P-B3, aiming at rapid development in return, after 6. ...  PxP; 7.  KtxP.  But Black can frustrate this plan either by pushing his pawn to Q6, so that the QKt is barred from the square B3, or by playing B-KKt5 with this probable continuation:  7.  Q-Kt3, BxKt; 8.  BxPch, K-B1; 9.  PxB, Kt-B3, and Black has the better game, for White’s King’s side is broken up and his pieces undeveloped, while Black has prospects of attack on the open KB file.

6.  P-K5 P-Q4 7.  PxKt PxB 8.  R-K1ch B-K3 9.  Kt-Kt5 Q-Q4
