Notes by Paul Diaconescu

C02. 1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6 6.a3!? The modern variation, with the idea of preventing Bb4+, which should force White to renouce castling. This move also prepares b2-b4, liquidating the pressure on the d4 pawn. c4! This move has been succesfully used in the Erfurt 1955 tournament and it queries the effectiveness of the 6.a3 system. Other possible variations give White a slight edge.

7.g3 In the game Bastrikov-Zukharov, Russia (ch) 1955. the game continued

[7.Be2 Bd7 8.O-O f6 9.Nbd2 fxe5 10.Nxe5 Nxe5 11.dxe5 O-O-O 12.a4 Ne7 13.b3 cxb3 14.Nxb3 and White was better.]

7...Nge7 8.Nbd2 Na5 9.Bh3 Until here we followed the game Dely-Franz, Erfurt 1955 in which Black played 9.Bg2 and he finally managed to achieve an edge.The text move doesn't seem to solve White's opening problems. Bd7 10.Nf1? A doubtful move which allows an immediate penetration of Black pieces into White's camp, before the latter can complete its development. The trade of N/B will be in Black's benefit. Nb3 11.Rb1 Nxc1 12.Qxc1 Ba4 Black fixes the weakness of the b3 square, paralysing all White's play on the Queen-side. 13.Ne3 Nc6 14.Nd2 h5! 15.f4 # g5!! An excellent move which breaks up White's position. 16.Kf2

[16.fxg5 doesn't work because of Nxe5 ( threatening 17... Nd3+) 17.Bf1 h4! And if 18.Ng2 then hxg3 19.dxe5 Qf2#]

16...gxf4 17.gxf4 Bh6 18.Nf3! A fine trap. O-O-O In the event of

[18...Bxf4? White will follow up with 19.Nxd5 Bxc1 20.Nxb6 axb6 21.Rbxc1 and White achieves a positional advantage after the manouver Nf3-g5-e4-d6 or f6.]

19.Ng5 # Nxd4! Black sacrifices a piece to blow up the center, increasing the value of his pair of bishops and exposing White's King to a strong attack. 20.cxd4 If

[20.Nxf7 then Nb3 21.Qe1 Nc5 22.Bf1 Ne4+ 23.Kf3 Bxf4! and Black is winning, for example: 24.Kxf4

(24.Nxc4 dxc4 25.Kxf4 Rhf8 26.Kxe4 Bc6+ 27.Kf4 Rxf7+)

(24.Nxh8 Bxe3 25.Ng6 Nd2+ 26.Ke2 d4 27.cxd4 Qxd4)

(24.Nxd8 Rf8!)

20...Qxd4 21.Kf3 More resistance should be offered by

[21.Nf3! Qxf4 22.Ng2 Qxc1 23.Rbxc1 Bxc1 24.Rxc1 etc.]

21...Bxg5 22.fxg5 Qe4+ 23.Kf2 Qh4+ 24.Kg2 Bc6 and White resigned because there is no defence against 25...d4+
