[what is this?]
Jeroen Piket was born in Leiden. He achieved the grandmaster title in 1989 and, until retiring from classical chess in 2002, was a regular participant in top international events. His results from these events distinguish him as one of a handful of players to defeat Garry Kasparov, Vladimir Kramnik and Viswanathan Anand in tournament play. His most notable tournament victories include Gronigen 1992, Dortmund 1994 and Tilburg 1996 (shared with Boris Gelfand). He also took first place in four Dutch Championships (1990, 1991, 1992, 1994).

Dec-24-08  zzzzzzzzzzzz: piket's good
Jul-15-12  achieve: For those interested in the Piket pronunciation: I submitted the correct one to CG and you can hear it by clicking the "PRONUNCIATION" button located at the top of the Bio section.

Piket's outstanding Hoogovens was in 1997, when he should have won; Jeroen stormed out of the Blocks with <5/6>, beating Salov in the first round, but threw away the tournament win by losing the final round game to Yermolinsky.

Jan-27-13  Kikoman: Happy 44th Birthday GM Jeroen Piket! ^^
Jan-25-15  Caissanist: Has there ever been any public information about what exactly Piket has been doing for the last thirteen years as a "personal secretary"? I did a google and there was absolutely nothing, not even a Facebook or LinkedIn page. He seems to be intentionally keeping a very low profile, I wonder why.
Jan-25-15  zanzibar: <caissanist> This article, in Dutch(?), has some speculation:

It's one of the wiki links on Piket's page.

Jan-25-15  zanzibar: <patzer2> quotes some of the article just above.
Mar-30-15  zanzibar: Beware of clickingon the link in the photograph above.

I get <Web Attack: Mass Injection Website> notice.

<CG> should deactivate the link.

Jan-27-17  diagonal: Happy birthday!

<Dutch Champion in 1990, 1991, 1992, 1994>. Dutch Junior Champion U13, U16, and multiple U20.

Won or shared first at Brussels Iclicki (Open) 1987, Spijkenisse (Mini-Tournament) 1987 (joint with WGM Nana Ioseliani), <Munich SKA-Mephisto 1989> (joint with Van der Sterren), Ostend (Open) 1990, <three-times winning in a row at Groningen GM in 1990, 1991, and 1992>: Groningen GM 1990, joint with Adams, Khalifman and Rogers, Groningen GM 1991 joint with C. Hansen, and Groningen GM 1992 outright. <Antwerp, Volmac Invitational 1993> (joint with Korchnoi, ahead of Christiansen, ten players), <Dortmund 1994> (clear first ahead of Adams, including Korchnoi, aged 60+, who beat in the tournament Karpov, Timman and Leko, ten players), <Antwerp, (4th) Lost Boys (Open)> 1.-3. shared with Van Wely and Ye Rongguang, <Tilburg 1996> (tying for first with Gelfand without either losing a game, ahead of Shirov, including also Leko, Karpov, Adams, Svidler, Lautier or Judit Polgar on last place, twelve players). <Biel 1999> (outright winner in a double round robin, six players), Vlissingen Hogeschool Zeeland Open 2001.

Dortmund ('94), Tilburg with Gelfand ('96) and Biel ('99) are his biggest tournament wins.

Piket also was =2nd-4th at Wijk aan Zee 1997, Salov won by half a point: As pointed out, Piket stormed out of the blocks with 5/6 points, beating Salov in the first round, but threw away the tournament win by losing the final round game to GM Yermolinsky.

In matches, Piket lost to John Van der Wiel 2½-1½ in 1986, lost to Viktor Korchnoi 2-6 in 1993, <beat Ljubomir Ljubojevic 6-2> and <beat Lev Polugaevsky 4½-3½> in 1994, lost to Alexei Shirov 5½-2½ and to Judith Polgar 6-2 in 1995, <beat Jan Timman 1½-½> and <beat Joel Lautier 2-0> in 1995, drew Anatoly Karpov 4-4 in 1999, and won an Internet match above Garry Kasparov.

In the friendly match against Lev Polugaevsky, Viktor Korchnoi acted as an assistant (second) for Jeroen Piket who worked himself several times as a second of Viktor Korchnoi.

A participant in the Olympiads between 1988 and 2000, Piket won a team bronze medal in 1988.

Also a member of the national team which won the European Team Championship 2001 where Piket collected an individual silver medal at board two.

Best ELO: 2670 in 1995, he was then the sole eleventh world ranked player. Jeroen Piket retired from chess at age of 33 in 2002; to become in the same year the personal secretary of dutch businessman and chess maecenas Joop van Oosterom.

Dec-08-18  Caissanist: I wonder what Piket is doing nowadays, now that the guy he was supposedly "personal secretary" for has passed on.

This made made me recall the most unusual job I had. Back in the 1990s, I had a part time job as an assistant to a private math tutor. The math tutor had Mysophobia.
I worked at his home. I opened and went through his mail, typed correspondence, graded papers, assisted him in his analysis of the stock market. He kept a distance from me. For example, when he opened the door to let me in, he stepped back and kept about a two feet distance from me.

According to his LinkedIn profile, Piket is a Treasurer for Dutch Investment firm Wereldhave. So safe to say that his Chess smarts have translated well into Real World smarts.

Jan-27-19  jith1207: I think as Piket had stated during retirement, he has secured a nice job for himself where he could be assured of financial security than what Chess would have provided.

I hope that puts the peace on the quest here about what he's doing these days.

Jan-28-19  Caissanist: I wasn't questioning his ability to make a living, just curious about what he actually did/does. I don't know what exactly he did for van Oosterman, but I think it's safe to assume that he wasn't answering phones or taking dictation, his "personal secretary" title notwithstanding.

This seems to be part of a larger trend in society. More and more skilled work seems to have rather nebulous and/or secret job responsibilities. Kinda makes it harder for young people who want to figure out what to do in life.

Jan-28-19  jith1207: I agree, it's good to be curious about what he has been doing. If I have to guess, I think the role is sort of personal management team but may be when you work for a billionaire, they are designated as Secretary? I guess in these circles, secretary takes a whole different meaning, like the one in White House or the one for the President. The role probably handles all management stuff for the boss and the company.

  OrangeTulip: it’s astonishing to read this stuff about Piket. So sad you have once in the twenty, thirty years a talent like that in Holland. But also so true he foresaw possible financial trouble arising. Like in music there are too much talents playing chess on a very high level, but without earning much. There are simply too many

  eternaloptimist: Happy birthday to GM Piket! After reading his profile, I can tell that he has beaten some of the best chess players of all time!
Aug-24-20  Illogic: Being concerned about his personal finances might have been a roundabout way of saying that Joop had offered him a huge salary. Likely he got made an offer he couldn't refuse.

Ré­su­mé and current work

It's fair to assume Jeroen Piket did not only do 'chess' around van Oosterom, but also developed an outstanding talent for cooking the books - 'proactive management with customised asset plan'.

Nov-03-20  Caissanist: Thanks for the link, to me it seemed rather obvious that he was probably doing something in the finance industry, where many top GMs and IMs have found successful second careers in recent years.

Nov-19-22  Peinalkes6: Piket was a fantastic player. His biggest wins were Dortmund Sparkassen 1994 (ahead of Karpov, Korchnoi, Timman, Adams, Leko, etc), Tilburg Fontys 1996 (with Gelfand) and the Kasparovchess2000 tournament (online) where he beat Kasparov in the final. Perhaps he lacked ambition and that could be the reason he didn't go further in the chess world. He definitely had the talent to compete with the best (and beat them). Perhaps he was no Anand or Kramnik, but they knew that Piket could beat them in his best days. We shall never forget this amazing player and person!
Sep-13-23  EphemeralAdvantage: Piket's games against the King's Indian are always very nice. Probably his most famous KID game is sadly his loss against Kasparov in 1989 (Piket vs Kasparov, 1989) but few remember that Piket played a crucial role in Kasparov not playing the King's Indian in the 2000s.

After Kozul's 13. Rc1 Ng6 14 c5!? (Z Kozul vs O Cvitan, 1990) made it into mainline King's Indian theory it was Piket who employed it successfully against Garry in the amazing draw Piket vs Kasparov, 1997. The game Piket vs Ivanchuk, 1999 which was featured in New In Chess Yearbook 51 was also theoretically important. One might even say that Piket picked up (10. Be3) where Korchnoi left off

This game and the subsequent evolution of the Kozul Gambit's theory, together with developments in the Bayonet attack (such as Sokolov's 10. Re1), finally convinced Kasparov to give up the King's Indian. He said that "it became too much work to keep up with two ultra-sharp black defences". I do not understand how he was doing it in the first place but that is Garry for you.

Piket was a wonderful player!
