a) 2 dxc5 e6 is easy equality. White should avoid the trap 3 b4? a5 4 c3 axb4 5 cxb4 Qf6.
b) Nc3 on move five or six transposes to the Banzai Benoni.
c) The Banzai exchange 7 ... Bxc3 is also equal.

  A43 Old Benoni Defense

Notes by Dr. Savielly Tartakower.
The building up of an attack by the second player - especially in an opening both peculiar and difficult to handle - is a special art. We shall be able to follow some its guiding principles here.

1 d4 c5
2 d5 d6
3 c4 g6
4 e4 Bg7
5 Bd3 e6

It will be noticed that Black carefully refrains from blocking the long diagonal either by 5 ... e5 or, even temporarily, by ; 5 ... Nf6.

6 Nc3 Ne7
7 Nge2

Here 7 f4 , followed by Nf3, leads to more straightforward development.

7 ... exd5
8 exd5 Nd7
9 f4 Nf6
10 Ng3 h5

Sounding the general attack.

11 O-O h4
12 Nge4 Nxe4
13 Bxe4 Bd4+
14 Kh1 Nf5

Black's attack has quickly assumed a concrete form. The text move announces the well-known attack by 15...Ng3+.

15 Bxf5 Bxf5
16 Re1+ Kf8
17 Qf3

White seeks to avoid fresh weaknesses; e.g., if 17 Be3 Bxc3 18 bxc3 h3 19 g3 Be4+ 20 Kg1 f5 or (20 ... Bg2 , and White's position remains restricted. )

17 ... h3
18 g3

Evidently not 18 g4?? Qh4

18 ... Qd7
19 Bd2 Bg4
20 Qf1 Qf5
21 Rac1 Kg7

For if 33 Ne2 Qg2 34 Rg1 Qxg1! 35 Nxg1 h2 0-1 , etc.
