European Champion 1965-66, 1968, 1972-73, 1975, 1979. http://strasbourg.jeudego.org/Europe.htm
Author of the book Go - der Richtige Zeitpunkt.
At the time of writing he demoted himself to 5 dan due to the influence of his terminal sickness.
He was born, raised and lived in Berlin. He was a student of psychology and gave up a job as an optician (I don't know in which oder tderz). He was regularly on fridays in the famous "Souterrain" pub (in Berlin) in walking distance of his flat. I tderz considered him a very friendly person and a very competitive one too. While he played with every one who was in a 9-stone handicap range, he also took great pride to mention his very positive score against several players: e.g. German player M.K. (solid 5dan at that time) "Never lost any tournament game against him" (that means at least 20 games in a row) etc.. And for sure he had positive records!
Late Manfred Wimmer? (2p, Kansai Kiin) when he returned from Japan, could not get a positive score against him (even I won (only) one even game against him (MW), in the Souterrain, hence only a pub game and usually he would give me 3 stones & play tricks in the taisha with me). Manfred Wimmer might not have been in such a good psychological shape at that time (being kicked out of Japan).
All of this shows that he had an overwhelming talent and love for this game. After all he became 5 dan (European strength) and 6 dan by himself and the study of some Go Reviews when the strongest environment was only about 3-4 dan.
Can you imagine what he would have achieved in an environment like Korea/China/Japan today?
He was a fast player - who also could also take his time of consideration in crucial moments: I remember a blitz game against Rob van Zeijst? where Jürgen took 5! minutes to calculate the effects of a corner defense (should he crawl for several moves on the 2nd line or not; I was too weak to remember the details) and he won this game in time!
He also gave Go lessons in the FU-Berlin (university) where I learned from him (as ~15k) and lots of other courses. While not having proper (well paying) jobs and living on students jobs etc., this seems to have been his deliberate choice.
Hans: He has already died but I do not know when. I guess in the first half of the nineties.
mgoetze: I am trying to find out but have not been successful so far.
tderz I think to remember it was 1997. I invited him for dinner 3 months before his death. Jürgen - I would like to change the page title with the Umlaut ü - won once a 2stone game against a Japanes professional 9d and not just anyone, but a title holder in its prime. I forgot and do not know who it was [1]. I want to get the name and the game record. This professional gave hime the comment that Jürgen "would be a good runner" (when several groups are competeing for access to the center). For sure Jürgen was a very good at fighting, something what might disrespectfully in Japan be called "peasant's style" (once I have read this), which is ok (I guess) in Korea. We could have learned so much more from him! It is such a pity that he is not anymore around.
He also had his times where he was into study chess, but then only in "studies" (I do not know much about chess, it seems to mean positional analyzes or so).
[1] Please mail me if you know the players name and the game record. I want to forward it to gobase.org. Jürgen is not properly repesented there for his achievements.
Could s.o. upload a picture of him?
