No, he just moved in with Polish-born Belgium champion Arthur Dunkelblum, which is to say, probably yes.
Andreas Duckstein

1) That was a "joke" as Dunkelblum died 30 years ago
2) I just wiki it and can usually find something unless the player is somewhat obscure
3) The Oxford Companion to Chess isn't bad for a book

oh come on be serious goldendog well if Duckstein was still alive today he would be 82 year old ! now is he dead or not ?

I don't know, Lilienthal is 98, Smyslov is 88, Averbach is about 87, Gligoric is 86, and Taimanov is 83. He could easily be that age.

here is the lastest so far 'New York Time' but the event was in 1993

here is another one from chessgame but the spelling is different is spelt Dueckstein and his games go up to 1998. As far as I know he is still playing even in this year, 'click here'
