St. Petersburg 1909, Game No. 90. Duras castles into a lost pawn-structure and stakes everything on attack; Spielmann refutes it.
8.O-OA mistake. The idea to retake at Q B 4 with the Pawn is good enough in itself. After the exchange at K 3, White's doubled Pawn, even though isolated, would do no harm, on account of its central position; it would hamper Black's pieces and could not be easily attacked. But it was a condition, sine qua non, to secure the Q Kt against B - R 4 by, say, P - Q R 3, for the trebled Pawn on the Q B file has no mobility whatever.
10.Nd5After 10) Q - Q 3, B X Kt; 11) P X B, P - Q Kt 3, the Q B Pawns would be fixed, and White's game should be lost in consequence. Hence White plays va banque for attack.
12.c312) P - Q Kt 4, Kt X Kt P; 13) Kt X Kt, B X Kt; 14) Q - Q 5, or 12) P - Q Kt 4, 13) B X P, Q R - Kt sq was more in the nature of a va banque attack.
