This is last series of suggested moves and a hell of a position for the computer to find itself in. ...22-24 are ...22.Nf4 23. Bxf4 exf4 24.Nf3 Qa4. This is the position.

On move 23. Kasparov is taking the trash this is what Deep Junior ran into on move 23.

After the 27th move Deep Junior has had enough and threw in the computer towel. The computer down but not out. Five years later mankind finds his computer enemy unbeatable with Kasparov retired. What a turn of events. Copyright 12-22-2008 all rights reserved used by permission of missing kasparov.

Oct-19-09  Kinghunt: What a brilliant game. Kasparov not only wins, but completely crushes Deep Junior in less than 30 moves in an open position in a tactical slugfest. Does anyone know if such a feat has ever been accomplished by anyone else? (Top of the line computer program, open position, and quick win?)

  thegoodanarchist: The computer has lost the exchange in 18 moves! This is an amazing game.

Well remember, Kasparov had computers
at home to work these things out.
Once a computer cant see or understand something its basically blind.
Im very sure he spent a lot of time with this positon. (in home analysis)

Its not just something thought up at the board.

All the same, I can't imagine anyone else playing such an aggressive opening against a computer in a serious match (especially not today). Sure, he used a computer to prepare, but he's the one who actually had to convert it. And he did it in the kind of position computers thrive in. That takes serious guts.

Jul-13-10  MaxxLange: Crazy like the fox? Or, crazy like the crazy person?
May-21-11  qqdos: Black for his first 6 moves has adopted a classic Colle System set-up in reverse.
Dec-26-11  The Rocket: As a matter of fact "Deep Junior decides to sacrifice the exchange but it was not forced.

One of the differences with this engine is the material value of the minor pieces seems to be almost equal even vs rooks so it all comes down to the evaluation of the actual positions. This makes it flexible to spot "out of the box" winning plans when sometimes exchange sacs win long term but also results with disasters when it evalutes incorrectly.

Also this was in 2003 this engine is approximately 320 points stronger at these time controlls today

this game multiPV by Stockfish

Nov-19-15  kubbybulin: Jr. Spots kaspy the exchange and 2 knights and then wonders how it could have lost.
Nov-09-20  Mehzinho: This was a great game for me to make a video analysis of.

Whilst analyzing this I was surprised by the sharp choice of Kasparov, and amazed by his flawless play. After 18 moves he was up the quality. He continued to play both illustrative and flawless to bring the win home.

You can see my work on this game here:

Nov-09-20  SChesshevsky: This Shirov-Shabalov 7. g4 line has a lot of teeth. Complicated and can be very dangerous for black.

Probably have to be familiar with it if a Semi-Slav defender and good to know as white if facing such a known defender.

Interesting that both Stockfish and AlphaZero apparently both won their matched games as white in this line. Both wins in less than 50 moves.

Dec-27-20  Duncan Leigh: Could someone please put me out of my misery and explain why the computer didn't just play Nxg4 on move 7?
