The Knight must move sooner or later.

10. ...  Castles
11.  Kt-Kt3 B-KKt5
12.  Q-B1

A sorry retreat, but the plausible Q-Q2 would be disastrous, e.g.  P-K6!; 13.  PxP, Kt-K5 and Q-R5ch

12. ...  B-Kt5ch

Black’s superior development begins to tell in no uncertain fashion.  Now White can neither play 13.  B-Q2 on account of BxBch; 14.  QKtxB, R-K1, followed by P-K6, nor 13.  Kt-B3 on account of BxKt; 14.  PXB, P-B3 regaining the pawn and maintaining positional advantage.  White has therefore no alternative but P-B3, which weakens his Q3, where a Black Knight soon settles down.

13.  P-B3          B-K2
14.  P-KR3         B-R4
15.  P-Kt4         B-Kt3

At last White can castle.  He can, of course, only castle on the Queen’s side, because his King’s side pawns are shattered.  Now games in which the Kings castle on different wings are more or less beyond calculation, as pointed out before.  On the whole, the player who first attacks wins.  But experience has shown that the Queen’s side is more difficult to defend on account of its greater expanse, and this theory is supported by the present game.  In addition, White’s development is not completed yet, whilst all the Black forces are ready to strike.

16.  B-K3            Kt-Q2
17.  QKt-Q2          Kt-K4
18.  Castles         P-Kt4

Storming the position with pawns is peculiar to this kind of game.  The intention is to break up the opposing pawn position, and to open files for the Rooks.  Pawns are cheap in such cases.  Open lines for the pieces are the things that matter, and the fewer pawns there are left, the more open lines are available for the attack.

          19.  PxP Kt-Q6ch
          20.  K-Kt1 QxP
          21.  K-R1

The King was not safe on the diagonal.  White wishes to push on his King’s side pawns (P-B4-B5, and so on).  But after PxP e.p. there would be a fatal discovered check by the Black Knight.

          22. ...  QxP

Black’s advantage becomes more marked.  He has recovered his pawn, and for the ensuing attacks on both sides he is better placed, having already two open files for his Rooks.

22.  P-KB4           P-QR4
23.  QR-Kt1          P-KB4
24.  Kt-Q4           Q-R5!
