Vaganian vs. Kupreichik

USSR Ch, Leningrad 1974

Trompowsky Attack

1 d4 Nf6 2 Bg5 c5 3 d5 A sharp alternative to the more positional 3 Bxf6. 3…Qb6 This must be the critical test of 3 d5 as White is forced to sacrifice his b-pawn. 4 Nc3 Qxb2 5 Bd2 Qb6 6 e4 d6 An alternative idea is to block the centre by 6…e5, e.g. 7 f4 d6 8 fxe5 dxe5 9 Nf3 Nbd7 with unclear play. 7 f4  g6?

After 7...g6?

It is a mistake to allow White to break through in the centre. Black should have put up  a fight for the e5-square by 7…Nbd7 8 Nf3 Qc7. 8 e5 An early central advance can sometimes rebound on the attacker, but not here as White has a lead in development to back up his aggression. 8…dxe5 8…Nfd7 9 Nf3 Bg7 10 Rb1  Qd8 11 e6 fxe6 12 Ng5 gives White a similarly vicious attack.  9 fxe5 Nfd7 10 Nf3 Bg7 11 Rb1 Qd8 12 e6! White strikes quickly before Black can castle. 12…fxe6 13 Ng5!

After 13 Ng5!

The advancing pawns have torn holes  in Black’s defenses; now the heavier pieces move up to exploit the weaknesses. 13…Nf6 14 Bb5+ Kf8 A sad necessity, as interposing on d7 allows 15 Nxe6.  15 dxe6 a6?! 15…Qd4 would have been a better chance, but even so , the position after 16 Ne2 Qd5 17 0-0 is very unpleasant for Black. 16 Be3! Qa5 Or 16…Qc7 17 Bc4 b5 18 Bd5 Nc6 19 0-0 Bb7 20 Nce4 with an enormous initiative. 17 0-0

After 17 0-0

White’s attack is so strong that he can afford to offer the bishop. 17…h6 17…axb5 loses to 18 Rxb5 Qc7 19 Nd5 Qe5 20 Bxc5. 18 Qd3 Exploiting Black’s new weakness at g6. 18…Kg8 19 Qxg6 Bxe6 20 Nxe6 Rh7 21 Rxf6 Nd7 22 Bxd7 1-0 It’s quite nice to take three enemy pieces on consecutive moves without any reprisal.
