GARRY KASPAROV
(born Apr-13-1963, 62 years old) Russia
PRONUNCIATION:
[what is this?]

One of the greatest players of all time, Kasparov was undisputed World Champion from 1985 until 1993, and Classical World Champion from 1993 until 2000. Known to chess fans world wide as the <Beast From Baku> on account of his aggressive and highly successful style of play, his main early influence was the combative and combinative style of play displayed by Alexander Alekhine.

Early Years

Originally named Garry Kimovich Weinstein (or Weinshtein), he was born in Baku, in what was then the Azerbaijan Soviet Socialist Republic (now the Republic of Azerbaijan), and is the son of Klara Shagenovna Kasparova and Kim Moiseyevich Weinstein. At five years old, young Garry Weinstein taught himself how to play chess from watching his relatives solve chess puzzles in a newspaper. His immense natural talent was soon realized and from age 7, he attended the Young Pioneer Palace in Baku (where for some time he was known as "Garry Bronstein".*). At 10, he began training at the Mikhail Botvinnik Soviet chess school. He was first coached by Vladimir Makogonov and later by Alexander Shakarov. Five years after his father's untimely death from leukemia, the twelve year old chess prodigy adopted the Russian-sounding name Garry Kasparov (Kas-PARE-off) a reference to his mother's Armenian maiden name, Gasparyan (or Kasparian).

Championships

Junior Twelve-year old Kasparov won the Soviet Junior Championship, held in Tbilisi in 1976 scoring 7/9, and repeated his success in 1977, winning with a score of 8½ of 9. The next several years were spent marking his rise as a world-class talent. He became World Junior Champion in 1980 in Dortmund, the same year he earned the grandmaster title.

National He first qualified for the Soviet Chess Championship at age 15 in 1978, the youngest ever player at that level. He won the 64-player Swiss system tournament at Daugavpils on tiebreak over Igor Ivanov, to capture the sole qualifying place. He was joint Soviet Champion in 1980-81 with Lev Psakhis ** and in 1988 Kasparov and Anatoly Karpov tied in the Super-Soviet Championship***. In 2004, Garry Kasparov won the Russian Championship Superfinal (2004) with a stunning +5 score.

World On the basis of his result in the 1981 Soviet Championship, which doubled as a zonal tournament for the USSR region, he earned a place in the 1982 Moscow Interzonal tournament, which he won, to qualify for the Candidates Tournament matches that were held in 1983 and 1984. At age 19, he was the youngest Candidate since Robert James Fischer, who was 15 when he qualified in 1958. At this stage, he was already the #2-rated player in the world, trailing only world champion Karpov on the January 1983 list. These Candidates matches were the first and last Candidates matches Kasparov contested, as he declined to participate in the Candidates held under the auspices of the PCA in 2002 to decide a challenger to his successor as classical World Champion, Vladimir Kramnik. Kasparov's first Candidates match in Moscow was a best-of-ten affair against Alexander G Beliavsky, whom he defeated 6–3 (+4 -1 =4). After much political ado, Kasparov defeated Viktor Korchnoi in London in the best-of-12 semi-final match by 7–4 (+4 -1 =6), and in early 1984 in Vilnius he defeated former World Champion Vasily Smyslov in the best-of-16 finals played by 8.5-4.5 (+4 =9 -0) to earn his challenge against Karpov. By the time the match with Smyslov was played, Kasparov had become the number-one ranked player in the world with a FIDE rating of 2710. He became the youngest ever world number-one, a record that lasted 12 years until being broken by Vladimir Kramnik in January 1996 and again by his former pupil, Magnus Carlsen in 2010.

At one stage during the Karpov - Kasparov World Championship Match (1984/85), Kasparov trailed 5-0 in the first-to-win-6 match. He then fought back to win three games and bring the score to 5–3 in Karpov's favour after 48 games, making it the longest world championship match ever. At that point, the match was ended without result by the then FIDE President, the late Florencio Campomanes, with Karpov thus retaining the title. Further details can be found in the match link at the head of this paragraph. Kasparov won the best-of-24 games Karpov - Kasparov World Championship Match (1985) in Moscow by 13–11, winning the 24th and last game with Black. He was then 22, the youngest ever World Champion, and broke the record held by Mikhail Tal for over 20 years. Karpov exercised his right to a rematch, the Kasparov - Karpov World Championship Rematch (1986), which took place in 1986, hosted jointly in London and Leningrad, with each city hosting 12 games. Kasparov won 12½–11½, retaining the title. The fourth match, the Kasparov - Karpov World Championship Match (1987) was held in Seville. Karpov had been directly seeded into and won the final match of the Candidates' Matches to again become the official challenger. Kasparov retained his title by winning the final game and drawing the match 12–12. The fifth and last championship match between the two, Kasparov - Karpov World Championship Match (1990), was held in New York and Lyon in 1990, with each city hosting 12 games. Kasparov won by 12½–11½. In their five world championship matches, the combined game tally was +21 -19 =104 in Kasparov's favour.

Kasparov subsequently defended his title against Nigel Short under the auspices of the PCA in 1993, and against Viswanathan Anand in 1995. Five years later, in 2000 (Kasparov - Kramnik Classical World Championship Match (2000)), Kasparov finally relinquished his crown to his former student, Vladimir Kramnik, who was granted the right to challenge without having to qualify, the first time this had happened since 1935, when Alexander Alekhine selected Max Euwe as his challenger. Subsequently, Kasparov remained the top rated player in the world, ahead of both Kramnik and the FIDE World Champions, on the strength of a series of wins in major tournaments.

Under the "Prague Agreement" which was put together by Yasser Seirawan to reunite the two titles, Kasparov was to play a match against the 2002 FIDE World Champion Ruslan Ponomariov in September 2003. But this match was cancelled when Ponomariov was dissatisfied with the terms of the contract. Subsequent plans for a match against 2004 FIDE World Champion Rustam Kasimdzhanov, to be held in January 2005 in the United Arab Emirates, fell through due to lack of funding. Shortly after this, Kasparov announced his retirement from competitive chess.

In an interview in 2007, Kasparov said that <…my decision in 1993 to break away from the world chess federation, FIDE, with Nigel Short was the worst mistake of my career. It was a serious miscalculation on my part. I thought we could start fresh with a professional organisation, but there was little support among the players. It led to short-term progress in commercial sponsorship for chess, but in the long run hurt the game...> ****

Classical Tournaments

In 1978, Kasparov won the Sokolsky Memorial tournament in Minsk as a wild card entry, a victory which convinced Kasparov he could aim for the World Championship. He played in a grandmaster tournament in Banja Luka, Yugoslavia in 1979 while still unrated, due to Korchnoi's withdrawal. He took first place with an undefeated record, two points ahead of the field. Game Collection: Banja Luka 1979 He emerged with a provisional rating of 2595, immediately landing at world number 15, a feat only surpassed by Gata Kamsky in July 1990. His first win in a superclass-level international tournament was scored at Bugojno, Yugoslavia in 1982, and his win in Linares in 2002 was the tenth victory in a row, a record for the most consecutive victories in super tournaments: Linares 4 (1999, 2000, 2001, 2002, Wijk aan Zee 3 (1999, 2000, 2001), Sarajevo 2 (1999, 2000) and Astana 1 (2001). Kasparov also holds the record for most consecutive professional tournament victories, placing first or equal first in 15 individual tournaments from 1981 to 1990. It started with the 1981 USSR Championship and finished in Linares in 1990. His five epic title matches against Karpov were held during this period. Subsequently, Kasparov won Linares again in 1992, 1993, 1997, 1999, 2000, 2001, 2002 and 2005, the latter being his swan song from the game.

Olympiads

Kasparov played in eight Olympiads. He represented the Soviet Union four times, in 1980, 1982, 1986 and 1988, and Russia four times: in 1992, 1994, 1996 and 2002 playing board 1 on each occasion apart from 1980 (2nd reserve) and 1982 (2nd board). In 82 games, he scored (+50 =29 -3), for 78.7% and won a total of 19 medals, including 8 team gold medals, 5 board golds, 2 performance golds, 2 performance silvers and 2 board bronzes. Kasparov also represented the USSR once in Youth Olympiad competition at Graz in 1981, when he played board 1 for the USSR board 1, scoring 9/10 (+8 =2 -0), the team winning the gold medal.

Team chess

Kasparov made his international teams debut for the USSR at age 16 in the 1980 European Team Championship at Skara and played for Russia in the 1992 edition of that championship. He won a total of five medals including at Skara 1980, as USSR 2nd reserve, 5½/6 (+5 =1 -0), team gold, board gold and at Debrecen 1992, Russia board 1, 6/8 (+4 =4 -0), team gold, board gold, performance silver.

Matches

<Computer> Kasparov defeated the chess computer Deep Thought (Computer) in both games of a two-game match in 1989. In February 1996, he defeated IBM's chess computer Deep Blue (Computer) with three wins and two draws and one loss. In 1997, an updated version of Deep Blue defeated Kasparov 3½–2½ in a highly publicised six-game match. The match was even after five games but Kasparov lost Game 6 - Deep Blue vs Kasparov, 1997 - to lose the match. This was the first time a computer had ever defeated a world champion in match play. In January 2003, he played and drew a six game FIDE Man - Machine WC (2003) match against Deep Junior (Computer). In November 2003, he played and drew a four-game Man - Machine World Chess Championship (2003) against the computer program X3D Fritz (Computer) X3D Fritz, although he was constrained through the use of a virtual board, 3D glasses and a speech recognition system.

<Human – classical> Kasparov played several matches apart from his matches in the World Championship cycles. Full details can be seen at Game Collection: Match Kasparov!.

<Human – rapid> In 1998, Kasparov played a blitz match against Kramnik in Moscow, that match being drawn +7-7=10. He fared better in the 2000 internet blitz match against Judit Polgar, winning one and drawing one. The following year, he played a blitz match against the many times Greek speed chess champion Hristos Banikas of Greece, winning 5 and drawing one. In his 2002 blitz against Elisabeth Paehtz in Munich, he won 6-0. Later in 2002, Kasparov lost a four game rapid match (+1 -2 =1) over two days in December 2002 in New York City against Anatoly Karpov. In 2009 in Valencia, Spain, he again played Karpov, and won the Kasparov - Karpov Rapid Match (2009) 3-1 and the Kasparov - Karpov Blitz Match (2009) by 6-2. In 2011, as part of his Chess In Schools campaign, he played a two game Kasparov - Lagrave Blitz Match (2011) in Clichy France, winning by 1.5-0.5. A few months later in October 2011, he won the Kasparov - Short Blitz Match (2011) 4.5-3.5 (+3 -2 =3), breaking the deadlock after game 7 by winning game 8 to win the match.

<Simuls> In 1985, Kasparov played his first simul against a team, the Hamburg Bundesliga team lead by GM Murray Chandler, and lost 3.5-4.5, the first and only time he lost a simul against a team. In 1987, he played a simul against the same albeit slightly stronger team, but this time he was prepared and crushed the Hamburg players 7-1; later in 1987 he also crushed the Swiss team: Game Collection: Kasparov vs Swiss Team Simul by 5.5-0.5, drawing only with former World Junior Champion Werner Hug. In 1988 he played a simul against the French team in Evry (Game Collection: Kasparov vs French Team Simul), winning 4, drawing one and losing one; he played the French team again in 1989 (Game Collection: Kasparov vs French Team Simul 1989), this time winning three and drawing 3 games. Also in 1988 he played a simul against a group of powerful US Juniors, and won by 4-2 (+3 -1 =2)*****. In 1992, Kasparov played a clock simul against the German team ( Game Collection: Kasparov vs German National Team Simul) which included former title contender Vlastimil Hort with whom he drew, winning 2 and drawing 2. He played a simul against the Argentinean team (Game Collection: Kasparov vs Argentinian Team Simul) winning (+7 -1 =4); in 1998 he played the Israeli team (Game Collection: Kasparov vs Israeli National Team Simul) winning 7-1, and in 2001 he played the Czech team (Game Collection: Kasparov vs Czech National Team Simul) in Prague, winning by +4 -1 =3.

Rating

Kasparov's ratings achievements include being rated world #1 according to Elo rating almost continuously from 1986 until his retirement in 2005. He was the world number-one ranked player for 255 months, a record that far outstrips all other previous and current number-one ranked players. Kasparov had the highest Elo rating in the world continuously from 1986 to 2005. However, Vladimir Kramnik equaled him in the January 1996 FIDE ratings list, technically supplanting him because he played more games. He was also briefly ejected from the list following his split from FIDE in 1993, but during that time he headed the rating list of the rival PCA. At the time of his retirement, he was still ranked #1 in the world, with a rating of 2812. In January 1990 Kasparov achieved the (then) highest FIDE rating ever, passing 2800 and breaking Bobby Fischer's old record of 2785. On the July 1999 and January 2000 FIDE rating lists Kasparov reached a 2851 Elo rating, which became the highest rating ever achieved until surpassed by Magnus Carlsen in 2013. There was a time in the early 1990s when Kasparov was over 2800 and the only person in the 2700s was Anatoly Karpov.

Other

Under Kasparov's tutelage, Carlsen became the youngest ever to achieve a FIDE rating higher than 2800, and the youngest ever world number one. Kasparov also assisted Anand's preparation for the Anand - Topalov World Championship Match (2010) against challenger Veselin Topalov. Since his retirement, Kasparov has concentrated much of his time and energy in Russian politics. He is also a prolific author, most famously his <My Great Predecessors> series. His politics and authorship are discussed at some detail in the wiki article and at his official website cited below. In 2007, he was ranked 25th in The Daily Telegraph's list of 100 greatest living geniuses and has won 11 Chess Oscars.

Kasparov has been married three times: first to Masha, with whom he had a daughter, Polina (b. 1993), before divorcing; to Yulia, with whom he had a son, Vadim (b. 1996) before their 2005 divorce; and to Daria, with whom he also has a daughter, Aida (b. 2006).

Oct-09-11  voyager39: <Akavall> Interesting indeed.

Mathematically speaking you (the lottery seller) will make an assured and increasing profit over an extended cycle. Over a short term however...luck may favour me if I can win in the first try.

My (unsound) answer is to buy 1 ticket from you and play not more than thrice :)

More important is to quit once winning or cut losses when I'm losing!

Look forward to the correct reply.

Oct-09-11  JoergWalter: <ughaibu, hms, voyager> stop dreaming.

<Akavall> wrote <I am only selling the tickets to you.>

Since I am not going to buy you can purchase an option from me at $5 only.

How's about that????

Oct-09-11  voyager39: <JoergWalter> Whatever...I am poor at reading the fine print is how I'd justify it :)

Meanwhile Kasparov leading 2-0 after 5 games. Typical aggresive and inuitive chess by Garry and some real sloppy play by Short.

Oct-09-11  JoergWalter: +2 -2 =3
Oct-09-11  voyager39: Garry is gonna hurt his reputation bad if he doesn't win the final game against Short whose rating is just 2698.
Oct-09-11  ughaibu: He could keep his reputation for tantrums and sour grapes.
Oct-09-11  voyager39: GK wins last game! +3 -2 =3

Level of play...nothing to write home about.

Oct-09-11  JoergWalter: and all the furniture in the hotel will stay in their places - intact.
Oct-09-11  Akavall: Here is the right answer:

As <voyager> noted <Mathematically speaking you (the lottery seller) will make an assured and increasing profit over an extended cycle.>

This is true of course, however, in this case there are only 3 tickets, and things become different.

Aside from you not buying a ticket there are 3 possible scenarios:

1) You win on the first try => +$15

2) You did not win on the first try, but win on the 2nd try => +$5

3) You did not win on the first two tries, but win on the last one => -$5

Therefore, your expected profit from this game is $3.33. So unless you are really, really risk averse you should play.

The key point here is that I will sell the tickets to you no matter what (I hope that was clear in the problem), because of that you are guaranteed to win $25 within 3 tries.

Oct-09-11  hms123: <Arkvall> With all due respect, I teach this stuff (and I was joking about my answer), but your write-up of the problem was not clear enough.

Having said that, probability problems are very tricky, and very hard to write in a crystal clear manner.

Oct-09-11  Akavall: <hms123> I think it was obvious that you were joking.

Which part was not clear? Was it the part that I am obligated to sell? I am asking since I like this problem a lot, and I want to be sure that I present it in clear manner in the future.

I know that one thing that I am missing is that I am essentially assuming that you are risk-neutral, which is probably true for money sums that small, but including all of that in the problem would only obfuscate things.

Oct-10-11  The Rocket: <"Level of play...nothing to write home about">

On the contrary first 4 games was the as good as it gets between humans in blitz. Kasparov then blundered material in his white game and suddenly we had a decider from nowhere.

Of course the last game kasparov put Short in his place

Oct-10-11  JoergWalter: <Akavall>

the traditonal mathematical way used to be this:

1.if you buy one ticket at $10 then the chance of getting the winning ticket is 1/3 so your expected win is 25/3 - 10= -5/3

2. If you buy 2 tickets the expected win is accordingly:

2*25/3 - 20 = -10/3

3. buying 3 tickets is simply 25 - 30

Anyone who considers buying a ticket from you will loose $1,67 per ticket. The fair price of the ticket is $8,33.

Oct-10-11  Akavall: <JoergWalter> The whole point in my problem is that due to the rules of the game, the buyer can benefit from seller having to sell the ticket no matter what, thus buyer can use the information he or she gets from every try.

Also, it is not rational for the buyer to buy two tickets at a time, because the buyer can buy one at a time. The difference here is that if the first ticket is winning then there is no point in buying the second one.

In my problem fair price of the ticket is $12.5

Oct-10-11  Big Pawn: Great blitz match between Short & Kasparov. But, Kasparov is like an old boxer - he should probably just stay out of the ring these days before he takes some unnecessary lumps. These exhibition matches are okay of course, but he would be clobbered by the new generation imo.
Oct-10-11  JoergWalter: <Akavall> I see your point.
Oct-10-11  ughaibu: But, "you did not win on the first try, but win on the 2nd try", if you dont win on the first try, then the lottery has been drawn. The second lottery doesn't then consist of two tickets, so it would revert.
Oct-10-11  Akavall: <ughaibu> I am not sure that I see your point.

There are 3 tickets to begin with, the seller is obligated to sell them. When the buyer buys the first ticket, there are only two left, so the second lottery would consist of two tickets; it does not go back to three tickets.

Oct-10-11  ughaibu: It would work if they were scratch cards, but not if it's a lottery, because a lottery selects a winner, it doesn't discard tickets as losers. Otherwise, the player cant know whether or not they've won, unless the game will revert to three tickets.

If it's scratch cards, one watches other people buy until there's a case of two losing tickets being sold, one then buys the third ticket.

Oct-10-11  ughaibu: If you mean that there are three lotteries, the first of three tickets, the second of two and the third of one, then the buyer will wait for the third lottery and win every time.
Oct-10-11  Akavall: <ughaibu> I see! Your point is very good, no wonder people had so much trouble with this :).

<If it's scratch cards, one watches other people buy until there's a case of two losing tickets being sold, one then buys the third ticket.>

I did foresee this; that's why the problem says: I am only selling the tickets to you.

Thank you, your input was quite helpful.

Oct-10-11  Akavall: <If you mean that there are three lotteries, the first of three tickets, the second of two and the third of one, then the buyer will wait for the third lottery and win every time.>

But that would never happen would it?

Why would anyone leave the third ticket, if they bought two losing ones? No rational person would. If you start playing this game you play until you get the winning ticket or winning scratch card.

Oct-10-11  hms123: <Akavall> This sentence <You can buy as many as you want, in whatever quantities you want, and as many times as you want> confused me. I couldn't decide whether I could by 10 of one ticket and 5 of another when presumably I couldn't distinguish one from another in the first place.

Sorry to be so dense.
