Neumann, Gustav Richard VS Anderssen, Adolf 1864.??.??

Annotations

1. 5…O-O A favorite defence of Professor Anderssen for some time, but he abandoned it ultimately as it does not yield a satisfactory position by best play on the other side.
2. 8.O-O This is not good. The right answer is 8 P×P, and if 8....Q—K sq.; 9 O—O, followed by P—Q4, with the superior game. But not 9 P—Q4 as Black would reply 9....QB—R3 preventing White's castling, with a strong attack. Likewise, if Black play 8....Q×P in reply to P×P, White answers 9 O—O.
3. 10.Nxc6 This gives White the inferior game. P—KB4 was much superior.
4. 11.Na5 His best plan was now 11 Kt—K5 as suggested by Herr Dufresne, or 11 P—Q5, 11 B—QKt2; 12 B—Kt5, 12 Kt×P, with the much superior game.
5. 13.Qd2 Here is a case where the King's side has been early left without any protection from minor pieces, and Black now wins by force. If 13 P—KB3, 13 P×P; 14 P×P, 14 Q—KR4; 15 R—B2, 15 Kt—K5 and wins.
6. 15…Bf3 Winding up with consummate skill.
7. 18.Qh2 No better is 18 Q—Q2, for then follows 18....Q—B8 ch.; 19 K—R2, 19 Kt—K5 and wins.
