Kasparov-Deep Thought 1997 (second game)

[Rodolfo Leoni]

I have read most of Dvoretsky's manuals in the original a long time ago.

but it is true, I somehow hate simple endgames and strongly prefer complex middlegame positions.

in the mg, your precious engines are even more clueless than what they are now, so much more easy to beat them.

why don't you also call Kasparov a troll, as he also supports the claim(after analysing with SF, btw.) the position is a white win?

knowledgeable people know what they are talking.

You need to study Averbach and to re-study Dvoretski before adventuring in such analysis. And about Kasparov, he isn't trolling here at all. You decided W wins despite any evidence and you continue asking them their CPU time until they'll grant you the fool's right.

[zullil]

anyway, white has so many winning lines, what if white deviates with 54.Qf3 instead of Qe7?

[d]3r2k1/6p1/3P1p2/4pP1p/1Pp5/2Pq1Q1P/6P1/R5K1 b - - 0 5

Looks like another draw:

Code: Select all

0.00 54... e4 55. Qxd3 exd3 56. Kf2 Rxd6 57. Ke1 Rc6 58. Kd2 Kf8 59. b5 Rc8 60. Rb1 Ke7 61. b6 Rb8 62. Rb4 Kd6 63. Rxc4 Rxb6 64. Rb4 Ra6 65. Rb2 Ke5 66. Kxd3 Kxf5 67. Rb5+ Kf4 68. Rxh5 Kg3 69. Rh7 Kxg2 70. Rxg7+ Kxh3 (depth 72, 0:25:23)

ok, Louis, I will look at it.

I suppose you used 7-men.

but I have the strong feeling to just leave it all here, as it is really extremely difficult to handle 10 people at once, you included.

I hope you have not joined the Dark Side of the Force, your SF, I mean?

I simply lack the physical ability to answer 10 people at once, not to mention analyse 10 different positions, obviously I should be skipping something.

besides, it is really nasty when people call you troll 10 times per day?

what for?

because I suggest an alternave opinion, or alternative moves?

this seems very much to me like a witchhunt.

I don't have 7-man endgame tables. I'm using the latest asmFish with 6-man tables.

No need to continue with this position. After

Code: Select all

45. Ra6 Qe3 46. Qxd6 Re8 47. Qd7+ Re7 48. Qc6 Qxe4 49. d6 

Black has no immediate draw. But deep searches suggest to me that the position is drawn. So I place the burden on you to prove otherwise, rather than on the rest of humanity to show that every line draws!

We've interacted here many times, and I enjoy your posts. I seem to be immune to whatever it is about them that drives many here into a frenzy.

Averbakh was a nasty person, and you are nasty too, so I preferred not to read Averbakh and concentrate on Dvoretsky instead.

I suppose you don't own other persons' cpu, to be responsible for how they choose to use it.

about the evidence:
- I demonstrated white win in 90% of the lines, right?; that is more than sufficient for me to claim the position is won for white. no one plays perfect chess.
- for the first time, I suggested Qb6 is the best move instead of Qd7, and thta has been confrimed by engine output, right?
- for the first time I suggest at least 5 or 6 moves apart from Qb6 and Qd7 lead to a white win, for example Ra2, and engines agree on that. no one else until now did that, right?

so, even if I can not manage, purely physically, all game variations, I still contributed a lot, much more actually then chessbase and other reputed analyticians.
I guess I am only due thanks for that, am I not?

because I opened your eyes.

btw., that is wikipedia has on game 2, including latest Kasparov remarks:

In this game Kasparov accused IBM of cheating, a claim repeated in the documentary Game Over: Kasparov and the Machine.[11][12] Kasparov eventually resigned, although post-game analysis indicates that the game could have been drawn. The game started with the Ruy Lopez opening, Smyslov Defence variation. In December 2016, discussing the match in a podcast with neuroscientist Sam Harris, Kasparov advised of a change of heart in his views of this match. Stated Kasparov: "While writing the book I did a lot of research – analysing the games with modern computers, also soul-searching – and I changed my conclusions. I am not writing any love letters to IBM, but my respect for the Deep Blue team went up, and my opinion of my own play, and Deep Blue's play, went down. Today you can buy a chess engine for your laptop that will beat Deep Blue quite easily."[13]

This game was played on May 4, 1997.
Deep Blue–Kasparov
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.h3 h6 10.d4 Re8 11.Nbd2 Bf8 12.Nf1 Bd7 13.Ng3 Na5 14.Bc2 c5 15.b3 Nc6 16.d5 Ne7 17.Be3 Ng6 18.Qd2 Nh7 19.a4 Nh4 20.Nxh4 Qxh4 21.Qe2 Qd8 22.b4 Qc7 23.Rec1 c4 24.Ra3 Rec8 25.Rca1 Qd8 26.f4 Nf6 27.fxe5 dxe5 28.Qf1 Ne8 29.Qf2 Nd6 30.Bb6 Qe8 31.R3a2 Be7 32.Bc5 Bf8 33.Nf5 Bxf5 34.exf5 f6 35.Bxd6 Bxd6 36.axb5 axb5 37.Be4 Rxa2 38.Qxa2 Qd7 39.Qa7 Rc7 40.Qb6 Rb7 41.Ra8+ Kf7 42.Qa6 Qc7 43.Qc6 Qb6+ 44.Kf1 Rb8 45.Ra6 1–0
At the time it was reported that Kasparov missed the fact that after 45...Qe3 46.Qxd6 Re8, Black (Kasparov) can force a draw by perpetual check (threefold repetition). His friends told him so the next morning.[14] They suggested 47.h4 h5!, a position after which the black queen can perpetually check White. This is possible as Deep Blue moved 44.Kf1 instead of an alternate move of its king. Regarding the end of game 2 and 44.Kf1 in particular, chess journalist Mig Greengard in the Game Over film states, "It turns out, that the position in, here at the end is actually a draw, and that, one of Deep Blue's final moves was a terrible error, because Deep Blue has two choices here. It can move its king here or move its king over here. It picked the wrong place to step." Another person in that film, four-time US champion Yasser Seirawan, then concludes that, "The computer had left its king a little un-defended. And Garry could have threatened a perpetual check, not a win but a perpetual check."

Modern chess engines consider the final position as better (but maybe not won) for white.[15][16] The mistake was actually not 44.Kf1 but 45.Ra6?! when instead 45.Qd7+ was a clear win (White will exchange Queens, bring his King to e4 and his Bishop to g6 after which black sooner or later is in Zugzwang, and will be mated, or lose his b5 pawn, or the d5 pawn advances, opening roads for the white king).

so that Kasparov acknowledges:

- he played weak
- Deep Blue played weak
- he analysed a lot with latest SF this position

in another book, he claims white is winning even after Ra6.

so, he analysed a lot this, and he is certainly a much better player than Nunn and chessbase team.

above claims, that Deep Blue and Kasparov played weak, are precisely met by my claims, so I don't see why you or anyone for that matter should accuse me of anything.

if anything, you should be grateful to me, not vice-versa.

sic transit gloria mundi.

thanks Louis, that is why I love you so much.

the first of your comments made my day.

I guess I will leave ti here for the moment, as I simply am already very tired by all the possible variations, and currently don't quite know which specific line I am analysing.

my firm belief is white is winning.

there are so many possible lines, and we are all, including engines, skipping something based on personal bias, so one never knows what will pop up in 10 years' time.

10 years ago, they still claimed after Qe3 h4 is the best white move...

chess is such a creature, that sometimes anyone can skip a move losing a knight but drawing the game instead for another one that is winning a knight but losing the game.

so complex, so we will possibly be back to this at some later point in time.

btw., do you know I already proved a forced black win in Glygorich-Smyslov?

thanks again.

Most things here aren't relevant at all. I've no time to comment all of them, but most of them aren't worth the effort, anyway.

Averbach isn't a nasty person at all. I knew him when I was a boy and I remember he was gentle and well educated. About me, just think what you want.

You decided W has a won position after 45.Ra6 Qe3 46.Qxd6 Re8 47. Qd7+ Re7 48. Qc6 Qxe4 49. d6 Qxf5+ 50.Kg1 Rd7. You decided that but you didn't perform any analysis. You only tried to play some moves. The position requires a good ending knowledge, and you admit you lack it.

Without that knowledge, you say 90% variations are winning lines for W. Here, you show you lack analysis method too. That's why you'd need to understand some Dvoretski too.

With that, I conclude my interventions here. I only consider this post was started by Franco Kanizsa. His first post. I wonder what impression he got from this nonsense.

maybe he can share his impressions.

I don't need good endgame knowledge, as I am seeing what SF shows for 90% of the lines - 300cps scores, and you know that very well too, in case you tried multi-pv.

Averbakh was an establishment figure, that says it all.

Hi Dann,

I tried to copy and paste your pv above to the position for easy replay,
the final position in above pv is also a book draw since the h4 pawn of
black cannot be captured. The h4 can only be capture in exchange for the
g2 pawn of white and white will have 1 last pawn at h3 which will only
amount to a draw.

Hi Dann,

I tried to copy and paste your pv above to the position for easy replay,
the final position in above pv is also a book draw since the h4 pawn of
black cannot be captured. The h4 can only be capture in exchange for the
g2 pawn of white and white will have 1 last pawn at h3 which will only
amount to a draw.

Even if analyzed using engines, white cannot make progress on your pv's final postion.

The final position of a pv is pretty well useless.
It contains crap like quiescent search nodes.

[MikeB]

so, chess base article is wrong: Ra6 was not a mistake, just not the best continuation.
