Ernst Franz Grünfeld was a contributor to the book of the Teplitz-Schönau 1922 Tournament, wrote a book on the Queen's Gambit ( "Queen's Pawn Openings" ) in 1924 and a two-volume general openings manual in 1950 and 1953. See www.schaakboek.nl
I don't know the books, perhaps somebody else can add info ?
Understanding the Grunfeld by Jonathan Rowson. Out of print. I am not fond of the Grunfeld, but this is one of the best opening books ever.
Addition to previous post :
I quote in original language : Das Kongress-Buch dieses Turniers ist eines der schönsten, das je erschienen ist. Es enthält eine Menge interessanter Aufsätze über verschiedene Schachthemen.
Seems to be a good book...
There is a forum here, called : " Best Chess Masters Biographies " and in post 2 you see a nice book by Grünfeld...
romy are you trolling, or do you just not realise he is looking for books written about the grunfeld opening, not books written by grunfeld?
Please explain, the word trolling is not in two English Dictionaries, so I am in doubt...
Yes, he is looking for that opening, I know, therefor I mentioned Opening Books in post 2 and post 4, and even the book in post 6 is not written by Grünfeld ( the word "by" is not good ).
Moreover there is no Grünfeld Opening, only a Grünfeld Defence, a Grünfeld Gambit and six Grünfeld Variations; see post 5, Ben is happy !
Hi, let's not split hairs ( is that the right expression? ) , I do my best to help people ! Regards, Ger.
Further to post 6 : The book is called " Der Variantenkoffer, Band 1, 1911-1920 " printed by the Wiener SchachVerlag, written by Michael ...(illegible).
" Variantenkoffer " is : Trunk, Box, Handbag, Suitcase --- full of Variations ! When that is not about Openings, I eat my hat !
Have a look on the forum called : " Why is the Grünfeld Defence not more popular ? "
