Kasparov-Karpov 1987 match, game 24 adjourned position

Post by nnnnnnnn »

Kasparov had to win game 24 (playing White) of his 1987 match against Karpov to retain his title. The position was adjourned after Kasparov's 42nd move Kg2:
[fen]5nk1/4q1p1/4p2p/1Q6/4B3/4P1P1/5PKP/8 b - - 4 42[/fen]


Could Black have held the position by just sitting tight (Black lost eventually after a later ...h5)? If so, where exactly did Black go wrong? If not, how does White break through? The pgn to the full game is below.

Your FEN for the diagram is incorrect. This is the right one:
[d]5nk1/4q1p1/4p2p/1Q6/4B3/4P1P1/5PKP/8 b - - 4 42

I will always regret that Karpov didn't save this game. Or scored the sixth win in 1984. I am sure that it would have changed the chess history altogether.

It is of course possible that SF misses something but from a short search it seems that today's programs agree that 45...h5 really was the move that gives the game away. Lots of other moves at that point give a +1.48 score which is just for the extra pawn and maybe a little for the Bishop, and that they all agree probably means that they transpose. See Blue Marlin here

This is without EGTBs , I did not check any continuations I don't remember the game I'm afraid, I don't know what Kasparove wrote later but it could be Karpov was tired or just did not prepare for Kasparov's last move or something similar? Costly mistake for Karpov, it could have ended differently.

are, by definition, not smart enough to debug it.

Hello:

If a single word must be used to define the WCC of 1987 in Seville (Spain), it would be 'drama'. Drama, drama, drama everywhere! In fact, the successful must-win situation in the last game did not happen since 1910 with Lasker according to ChessGames!

I do not bring analysis of the game but some videos, photos and reports outside YouTube that could be more difficult to find.

------------------------

There is a book called Garry Kasparov on Garry Kasparov, Part 2: 1985-1993 where games of 1987 WCC are featured. Sometimes, there are free previews of the book at Google Books, but it depends on the pages. I found a text only version where the keyword is the date "19.12.1987" (without quotes). Then you can go through the game with some comments and the times remaining on each clock after the games, which slightly differ from other source given below.

------------------------

The event was covered by the national Spanish TV corporation. One example is its appearance at Informe Semanal (literal translation: 'Weekly Report', which still runs each Saturday night). Here is the video in Spanish language:

Kasparov - Karpov: duelo en Sevilla. (Aired on 12th December, 1987).

It was aired in the later stages of the Championship, with two games remaining. However, it is very interesting because we can see images of the preparation of the venues, the chess set with the special rook —inspired by a local monument of Seville called Torre del Oro—, the change of the knights from the original set, the change of the chair by Karpov, how computer chess software looked like at that time (on topic in this forum) and many other things. The chess set itself has own threads on the Internet. I bring two from chess.com (#1 and #2).

The chessboard is still in a chess club of the city according to #1 thread (third photo of the original post). There are expositions from time to time, like the following one:

The different chairs are quite evident in this photograph.

------------------------

The chess games started at 4:30 PM local time and were adjourned if needed. The article of best selling Spanish newspaper El País on the first part of the last game even includes the ticket prices: 200 to 400 pesetas (the Spanish currency back then) in the box-office, reaching 8000 pesetas at resale. Claculating to today prices:

Code: Select all

€ 1 = 166.386 pesetas (fixed at New Year's Eve of 1998)
https://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:1998:359:0001:0002:EN:PDF

Official conversion rates of 31st March, 2022 according to BOE (Spanish Official Gazette):
https://www.boe.es/boe/dias/2022/04/01/pdfs/BOE-A-2022-5232.pdf
€ 1 = $ 1.1101  (US)
€ 1 = £ 0.84595 (UK)

Inflation from December, 1987 to March, 2022 according to INE (official agency in Spain):
https://www.ine.es/varipc/verVariaciones.do?idmesini=12&anyoini=1987&idmesfin=3&anyofin=2022&ntipo=2&enviar=Calcular
178.6% (Spain).
168.7% (Andalusia).
(These values are variations: 100% means a doubling).

Taking the national value of variation:
Pesetas from December, 1987; €, $ (US) and £ (UK) from 31st March, 2022:

p pesetas = € p/166.386 (nominal value) = € 2.786*p/166.386
p pesetas ~ € 0.016744197*p

p pesetas ~ (€ 0.016744197*p)×(1.1101  $/€) ~ 0.018587733*p
p pesetas ~ (€ 0.016744197*p)×(0.84595 £/€) ~ 0.014164754*p

Ptas.      €       $ (US)     £ (UK)
 200      3.35       3.72       2.83
 400      6.70       7.44       5.67
8000    133.95     148.70     113.32
I wish I am right: in today standards, less than {€, $ (US), £ (UK)} 10 at box-office and more than {€, $ (US), £ (UK)} 100 at resale. Here are the articles of the first and second parts of the last game of the Championship, with brief comments on some moves:

Kasparov aventaja en la última partida a Karpov, que hizo frente con éxito al reloj
Kasparov retiene el título al forzar el abandono de Karpov en la reanudación de la última partida

------------------------

ABC is other Spanish newspaper that also featured the event, this time in descriptive notation. Here are some pages:

First part of the last game:
Parte del público celebró la casi segura derrota de Karpov cuando su reloj llegó al límite
Ventaja de Kasparov en la última partida del Mundial de ajedrez, que quedó aplazada
La última partida, de dramático desarrollo, se aplazó con clara ventaja de Kasparov

Second part of the last game:
Kasparov ganó la última partida y conserva su título de campeón del mundo de ajedrez
Gari Kasparov retuvo el título de campeón al ganar la última partida, aplazada el viernes

Full page versions are available with the expand button on the bottom right side of each page.

------------------------

Last but not least, the Spanish referee of the referee committee of that event wrote a list with curiosities of the match (in Spanish language), such as how Seville was designed the host city ahead of Abu Dhabi and Madrid, some budgets, renting of houses for both teams, the special chess set with the famous rook, the names of people in Kasparov's and Karpov's teams, GMs covering the event (Spassky, Tal, Smyslov, Korchnoi, etc.), anecdotes (new, smaller chessboard; 40/150 time control; times remaining after games —slightly different from other source above—; etc.) and some photos of stamps, the chess board, set and clock...
