Avrukh Boris - 1.d4 volume one

The readers of this book have hit upon the best way out of the dilemma: the brilliant theoretician and profound analyst Boris Avrukh is sharing his recommendations with them, in all the closed openings. Mikhail Botvinnik and Viktor Korchnoi used to divide chessplayers into those who create opening theory and those who utilize the results of these labours.

The reason for this is quite simple. The openings after 1.d4 are for good reason called closed, as it is harder to launch an immediate attack on the opponent when you have not opened up the development of the kingside pieces, as you do when you play I.e4. Among other things, this leads to less forcing positions. For this reason, it is less likely that the opponent will manage to analyse the opening all the way to a position where there is not much play left, where the draw is close; the opportunity to outplay your opponent is kept alive.
