Garry Kasparov's Most Memorable Moments | Part 3 | 19 Move Loss Against IBM's Deep Blue

Kasparov was very smart to chose the Karpov variation 4....Nd7. This way, when he lost, he could blame Karpov.

[@Muzzikar]

In his book, "Deep Thinking" he talks about the knight sacrifice on page 215-216. "I was aware of Nxe6, I was also aware that it would be a killing move it Deep Blue played it against me. I just simply knew it wouldn't. Machines are speculative attackers, they need to see the return on investment before they invest material." Going on to quote a coach of the machine, Miguel Illescas: "On the same morning, we introduced the move Nxe6 in the Caro-Kann, on the same day that Kasparov played it. That very morning we told Deep Blue, if Kasparov plays h6, take on e6, don't check the database. If Deep Blue were allowed to think for itself on the move, it would never have played it."

[@Rocksite1]

So, he played a known bad move, based on an assumption about how the computer program worked; not based on good chess. Therefore, the outcome of this match turned on the quality of the book, more than Deep Thought's calculating power (if your source can be substantiated).

[@videoxplorer]

[@omkarparopkari]

I just don't understand why people compare like that. And if you are to compare, how does Fisher stand a chance? How can anyone look at his games, and compare them to today's theory, and say Fisher would have done well? You don't need to be a chess expert here really, just need to be a ~2000 or more to know that Fisher was great for his time, and will be remembered as one of the best ever in the game, but Kasparov would have crushed him, and so could most super GMs today. It's a nonsensical discussion on the outset, and the conclusion is nonsensical still.

There's so much more to this game than what was said here. By game six Kasparov was extremely exhausted. This whole match he was playing passive chess because IBM refused to give him the games deep blue had played against other GMs in preparation, not giving Kasparov a chance to prepare. Even then during the second game, he laments in his book that he was so caught up in the thoughts that the Deep Blue team was cheating he missed several chances leading him to resign prematurely.

“The passion for playing chess is one of the most unaccountable in the world. It slaps the theory of natural selection in the face. It is the most absorbing of occupations.

[@SurfinScientist]

One of the weak points of IBM was that they denied Kasparov a rematch. That made their win much less convincing. I still dread that they got the Turing award for this malperformance (and I say this as a computer scientist).

[@patriceaqa288]

SurfinScientist do you 'really' think Deep Blue's creator's cheated in creating new strategies for the machine between intervals and matches based on the pattern of play? Because I've read so much about this having played my whole life, and have never found anything credible to support that hypothesis. I think there was an element of 'choking' in the loss to Deep Blue, chess is still a sport after all. Nervousness that this was going to be 'much' harder than anticipated perhaps affected Kasparov's play

[@SurfinScientist]

@@patriceaqa288 I did not talk about cheating by IBM. I just said that IBM should have allowed a rematch to Kasparov, because he also allowed them a rematch. That is real sportsmanship. But for IBM this was not about sportsmanship, but about commerce. A rematch would also have contributed to science at the time. I found IBM's win less convincing due to the lack of a rematch.

[@patriceaqa288]

@@SurfinScientist Just to confirm Kasparov quit in the first, lost in the second and their never was a trilogy or am I wrong about that? Or was it a draw, then a IBM victory and no trilogy?? Please help me remember? Because I've read extensively about Kasparov claiming fanatically that the engineers were 'feeding' the machine information between rounds to help facilitate the 'victory' so to speak. It's been a decade since I've pondered this.

@@SurfinScientist If you 'know' any relevant or decent sources which could better explain potential 'cheating' on the part of IBM please reference them for me.

If you have any links to help better understand those allegations outside of Kasparov's mouth I'd appreciate hearing them. Thanks. Peace

[@parthsavyasachi9348]

@@patriceaqa288 there will be none. Though in my subjective opinion Kasparov have a point here because back then the "engine" was not AI based but rather a type of optimization search algorithm. Now these algorithms should go to the states where the material loss is minimal. So for that algorithm to give up a whole piece for a pown doesn't compute. Hence the allegations that human guided the movie. Now the engines learn by playing and for them play is very different.

[@johnwarner3968]

Thanks for the game! I bought the book and remember the big controversy of Deep Blue being aided by and overruled by “three nameless GMs”. IBM was very embarrassed by the first match and thought their programming sales would plummet if they lost again. I tend to believe Kasparov in this situation. Kasparov claimed that Deep Blue was reprogrammed “during the match” to be able to beat him, which was against the initial rules of the match. It would be interesting to replay this game using one of the newer programs for Deep Blues moves.

[@TG-to5nf]

+Liam Fields Thanks :)

[@abj136]

Game 6 of all the match games was the least interesting chess-wise. Kasparov was already very demoralized at this point, wasn't thinking clearly or motivated to win, but distracted by his feeling the IBM team cheated. And walked into a known opening trap.

[@pauldraper1736]

All mistakes: * 2:43 h6, the biggie. Remarkably, that was played in 83 master games. (When white responded Nxe6, it won 71% drew 11%.) * 4:02 b5. He could have played Qb4, allowing dark square bishop to develop and avoiding e6 pin. . * 4:47 Kc8. To account for axb5, should have played a6 or Nc7. * 4:59 Bc6. As agadmator suggets, Nc7 is better. The defense for the attack on c7 is getting the light square bishop to c4.

[@stateofdecay2210]

I was about to be disappointed of your channel then finally I found it I found the game I was looking for and it is one of the reasons why your channel is so great and awesome , thank you

[@paysdoc]

Just a quick question - actually 2 1. Would it be possible to display the move number on every move when you do the walk-through? Or perhaps you do but I haven't discovered it yet. 2. When Kasparov played Bishop -> c6 (I think move 16 or 17) what would have happened if he'd played Queen -> b4 instead? It would seem like he'd unpin his pawn and effectively pinning either the rook on a1 or the knight on f3

[@bestvitalic]

Actually Kasparov was angry because of the opposite reason, game 2 was probably the reason why Kasparov lost this match, where Deep Blue played Be4, closing any counter-play by Kasparov, he finally collapsed under the pressure and lost the game, but later analysis showed that game 2 was actually a draw and the move Be4 that Deep Blue played was a blunder! Computers always were good at tactics, because they just calculate positions, of course with some heuristics, but they don't play real strategic games, Be4 was a strategic move!

[@dannygjk]

(sigh) Sometimes computers find positional moves, not by the criteria used by humans, but by examining a zillion lines then finally their evaluation function chooses.

I remember this like it was yesterday...having played chess on the college team, for myself, there seemed something very ominous and frightening about a computer beating The Great Gary Kasparov. Maybe I seen to many “Terminator” movies....

[@5inthehole]

I remember this very vividly, as someone who studied Psychology and Philosophy, and was taking back by the implication of a computer outthinking a man. But when I heard Kasparov statement that the machine had some help, that made sense to me. No matter how much memory a computer has or how fast it can process, it should never be able to beat a player of Gary Kasparov talents on its own.

[@a.m.armstrong8354]

Kasparov misjudged his opponent's limiting factors. As he was a 'psychological' player, he convinced himself he knew the parameters by which the programming was structured. Studies have shown Capablanca is the most 'accurate' player historically. I believe Capablanca would have played the position and not 'the program' to achieve a different result.

Unfortunately, probably not. Deep Blue relied on massive parallel processing to evaluate millions of moves. To do this, it had a huge number of processors connected across two large cabinets of hardware.

All it takes is for someone to tweak the time the computer spends on the moves and to ask it to "look at" moves like Nxe6.

All kasparov had to do was play a move like Rb8 which is a decent tempo attacking the queen.... also deep blues King is currently stuck on the back rank which can easily lead to a back rank mate....
