Another very good guide to IQP is it's chapter in Chess structures: A grandmaster guide by Mauricio Flores Ríos.
IQP is, if you ask me, bread and butter of chess and should be introduced to begineers way earlier than it tends to be. Plans for both sides are clear and thematic (consequently less memorization in opening is needed), it's imbalanced and based on piece play (consequently tactics and calculation) more than on abstract considerations.
Agreed! But it's hard for beginners and intermediate players to follow that kind of path without a culture of coach-directed learning. For best effect, a gruff, grizzled, Soviet coach.
