7.  PxP B-Q2

Not KtxP, 8.  KtxKt, QxKt, because of B-Kt5ch.

8.  B-K2

The B cannot go to B2 on account of Kt-Kt5 and B-Kt4.

8. ...  KKt-K2
9.  P-QKt3 Kt-B4
10.  B-Kt2

Now White’s centre is safe from further attacks.  True, White has forfeited castling, but as he dominates the King’s side, where Black cannot undertake anything, there is no harm in P-Kt3, preparatory to “artificial castling.”

10. ...            B-Kt5ch
11.  K-B1          B-K2

Directed against 12.  P-Kt4, driving off the Kt.  Now Kt-R5 would follow.

12.  P-Kt3 P-QR4

Diag. 139

This manoeuvre is unwise; White counters with 13.  P-QR4, a move which was necessary in any case, in order to develop the QKt via R3, this being the Knight’s only chance of getting into play, because, as long as the QP is attacked three times the lines of B and Q must not be interrupted.  That is a weakness in White’s game, and it was necessary for Black to prevent his Kt being driven off by P-KKt4.  P-KR4 was the correct move.  Then White also had to play P-KR4 to prevent P-KKt4-5, in which case Black could have played l3. ...  P-KKt3, and have brought his Rooks into concerted action.  P-KKt3 would have been necessary before castling, because White’s B-Q3 would have attacked the KKt.  The latter could not then capture the Queen’s Pawn on account of a discovered check, e.g. l2. ...  Castles; 13 B-Q3, KtxP?; 14 KtxKt, KtxKt; 15 BxKt, QxB?; 16 B-R7ch, and QxQ.

In Diagram 139 Black’s P-QR4 is not only a lost move, but moreover allows a White piece to settle permanently at QKt5.  It also prevents the Knight from playing to QR4, from where White’s P-QR4 could be answered by Kt-Kt6 eventually.

13.  P-QR4         R-QB1
14.  B-Kt5         Kt-Kt5

All these skirmishes only result in the exchange of pieces, and as long as Black’s KRis out of play this can only be of advantage to White.

          15.  Kt-B3 Kt-QR3

This is in order to drive off the B. Black should have exchanged his own inactive QB, as the White B might become effective on the Diagonal QKt1-KR7, whilst Black’s QB has no future.
