"I think that I can get more out of d4" ++ Dream on. At the Yekaterinburg Candidates' 1 e4 was both played more and more successful. Against 1 d4 the Grünfeld was played 5 games: all 5 draws.
"To learn the theory I will learn the two volumes of Avrukh." ++ That is the wrong approach. If you want to play it, then just play it. No need to study 2 volumes before. You can always look up after you played a game.
"a modern game collection of d4 games" ++ Any data base. I suggest to study the games of the Yekaterinburg Candidates Tournament.
Hello,
I want to switch from 1.e4 to 1.d4 because I think that I can get more out of d4 and the structures are more favorable for me. I also thought about Nf3 but I will probably choose d4 with some catalan set ups. To learn the theory I will learn the two volumes of Avrukh. I also want to learn structural ideas and therefore I wanted to ask after a book about d4 structures (catalan, Benoni, slav etc.) or a modern game collection of d4 games.
