Classic Chess Games: Teichmann vs. Spielmann
White: Teichmann, Richard
1. e4 c5
2. Nc3 e6
Advantages of this move depend on the way Black plays. It will be equivalent to Nf3, after the moves d4; cxd4 and Nxd4. On the other hand if Black moves his pawn to d5 White benefits from having the Knight placed at e2 instead of f3. For example if play continues ; 3 d5; 4 exd5 exd5; 5 d4, and if Black refuses to exchange the pawns here, White will use his White squared Bishop developed to g2 after g3, to put pressure on the central squares.
3. ... Nc6
White should not worry too much about this Knight since it can be exchanged, making the move e5 feasible. When he thinks it will be beneficial to him White will play e5, in order to chase away the Black Knight's expected movement to f6.
It may be better for Black to use the move Qc7 instead of 3 Nc6 to forestall e5. The system of defensive moves that involves the Black's move Qc7 has a long history and was publicized by Paulson. His defense while hampering the movement of Black's Bishops and Knights, gives him a rock solid defensive platform. It also allows attacking opportunities in the queenside through the open c file. The play may proceed; 2 Nc3 e6; 3 Nge2 a6; 4 d4 cxd4; 5 Nxd4 Qc7; 6 Be3 Nf6; 7 Be2 Be7; 8 O-O b5, with Bb7, d6, Nd7, etc. to come shortly.
4. d4 cxd4
5. Nxd4 a6
6. Nxc6 bxc6
7. Bd3 d5
8. O-O Nf6
9. Bf4 Bb4
This move is incorrect here. White can compel Black to play g6 which weaken the king-side, when White plays e5 and Qg4. Black should have prepared for that by playing g6 preemptively, so that after e5 his Knight can move to h5 and still be available for the protection of king-side. After 9 Bb6 Black's only piece available for the king-side defense becomes vulnerable. As a result White's assault will end in victory.
10. e5 Nd7
11. Qg4 g6
12. Rfe1 c5
Black should not take the offered sacrifice of the exchange since it will get him into difficulties. For example after he accepts it by moving 12 d4, the play may continue; 13 Ne4 Bxe1; 14 Nd6+ Kf8; 15 Nxc8. Black is well and truly trapped, and cannot avoid mate since his defensive pieces will take too long to mobilize properly.
However 12 c5 will not get Black out of his difficulties either. White will embark on a superb sequence of moves to bring the game to an excellent conclusion.
13. a3 Ba5
14. Bg5 Qb6
Qc7 will not alter the approaching doom.
15. b4! cxb4
16. Nxd5 exd5
Now it becomes clear why 15 b4, is considered a brilliant move. If white did not make it, Rook at e1 will now be under threat from Bishop.
17. ... f5
If Black played Nc4, 18 exf7+ Kxf7; 19 Re7+ and Qf4 will win the game for White.
This is a double check.
