Kasparov, you would have to play Blackmar-Diemer...

back to main

After seeing boring matches human - machine there is possible that much people believe that is very difficult to gain some advantage against the programs, and even that is impossible to gain any advantage using tactics. Nevertheless it is possible and even simple to obtain to advantage using gambits against the computers. Particularly I can assure to them one thing: is easy to obtain winning advantage in the first 10 to 15 moves against majority of the programs with the Blackmar-Diemer Gambit. I show an example like the following game played in under the modality of Advanced Chess against another program.

Blackmar-Diemer Gambit [D00]

1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 Bg4 the Teichmann defense to Blackmar-Diemer Gambit (BDG). 6.h3 Bh5 7.g4 Bg6 8.Ne5 c6 9.Bg2 Looks like a promising continuation but in connection with the following sacrifice of pawn. 9... e6 10.0-0! Sacrificing a pawn for attack! [ 10.h4 This continuation is possible and very interesting, too. 10...Bb4 11.Bg5 ] 10...Bxc2? Is it correct to eat every pawn?... I doubt that very much. [ 10...Bd6? It seems the best answer. 11.Nxg6 hxg6 12.Qf3... Quiñones, Jorge - Rouse, Phil  WC-2006-P-00011 (in progress). ] 11.Qd2 Bg6 12.Qf2 Black is practically lost in move 12, all Black's answers give White clear advantage. 12...Qe7 Black decides to cover f7.

Preparing the sacrifice of the white-squared bishop White covers d6 square. If Black moves knight on b8, then the bishop on f4 covers possible queen's withdrawal to d6 after Bxc6. 13...Nbd7 [ 13...Nfd7 14.Nxg6 hxg6 15.Ne4 Nf6 16.Nd6+ Rd8 17.Be5 g5 18.Nxb7+ Dxb7 19.Bxf6+ Rc8 20.Bxg5 ±; 13...a6 14.Rac1 Nbd7 15.Bxc6 Qb4 (15...bxc6 16.Nxc6 +-) 16.a3 Qb6 17.Na4 Qa7 18.Bxd7+ Nxd7 19.Nxd7 Kxd7 20.Bc7 Ke8 21.Nb6 +-; 13...Qb4 14.g5 Nfd7 (14...Nd5? 15.Nxd5 exd5 16.Nxg6 fxg6 17.Rae1+ +-) 15.Nxg6 hxg6 16.Bxb8 Rxb8 17.Qxf7+ Kd8 18.Ne2 e5 19.Rad1!
