Jul-22-11  Oceanlake: The opening of the future....
Jul-22-11  swr: 1996 - the good old days, when it was this easy to beat a computer.
Jul-22-11  DrMAL: Shredder was ahead until move 15, when it made a poor move. Then, on move 16 it steps into a quick mate. Was there a big thunderstorm going on?

Just for grins (hash cleared):

Houdini_15a_x64: 9/27 00:00 126,393
+M5 17.Bxh7+ Kxh7 18.Rh3+ Kg8 19.Qh5 f6 20.g6 Bxf4

Figured out in about 30 milliseconds LOL

  Check It Out: My Shredder so did not fall for this. As a matter of fact, it can't stop laughing at me. Oh shut up.
Jul-22-11  DrMAL: I think ole Steinwender poured his coffee in it.

  HeMateMe: You always learn something new here. I'd never heard of the Amazon Attack before. Do any GMs ever play it?
Jul-22-11  DrMAL: W Pollock vs Max Weiss, 1889 has 2.Qd3 (apparently, defines the Amazon attack) Maybe 3.f4 is a tributary? Pollock was an IM, I guess that is as close as it comes...

  Nightsurfer: THIS GAME is a MILESTONE!

Dieter Steinwender who is one of the pioneers of computer chess, please read http://chessprogramming.wikispaces...., demonstrates his famous KARATE-CHESS in a very convincing way. KARATE-CHESS has been Dieter Steinwender's special way to get the programs out of the books - and his KARATE-CHESS-style opener against dreaded SHREDDER has been THE AMAZON ATTACK 2.Qd3 ...

Therefore Steinwender has succeeded in brilliantly outplaying SHREDDER that was already strong back then in 1996 - though SHREDDER is probably somewhat stronger today, for sure, with a rating of ELO 2824 or so :-) ...

Witnesses who have watched SHREDDER's defeat against Steinwender in 1996, they have reported that German programmer Stefan Meyer-Kahlen, the creator of SHREDDER (more information at:, was devastated after he had to accept that Steinwender had transformed the so-called electronic "killer" named SHREDDER into a pretty harmless toaster ...

Thank you so much for posting that game that has written history!

Jul-22-11  abuzic: 14...Qc7 (14...g6, or ...Ne7 keeps black ahead) 15.g5 Ne8?? (15...Ne4! saves the N and avoids the following mate) mate in 5: 16.Rxh7+ Kh8 17.Qh5 Nf6 18.gxf6 g5 19.Rxg5 Bxf4 20.Bg8#

  kevin86: Interesting second move:I never even thought of it.

Man shreds machine: the good old days.Like the old days when the USA teams used to win in sports.

Jul-22-11  DrMAL: <kevin86: Interesting second move:I never even thought of it.> That's probably a very good thing LOL.

Not sure if the witnesses to this game were part of a collusion to short circuit the computer! :-)

Jul-22-11  Amarande: Perhaps most attractively: if 17 ... Kxh7 18 Rh3+ Kg6, the mate arrives with 19 Qh5+ Kf5 20 Ng3+ Kxf4 21 Nb1#.

The books always said to develop your pieces. Sometimes it's better to go home again. :) (Actually, any move of the White Nd2 on move 21 will do, but there's just a very fun flouting of the general principles by making the mating move that results in both the moving piece and mating piece being *on their original squares* at the end!)

Jul-22-11  WhiteRook48: classic.

  beenthere240: According to Shelby Lyman, this opening (2. Qd3) was favored by Napoleon, who used it to achieve many losses.
