Recommendation of a book for learning strategic concepts I am looking for a book to help me with strategic concepts, how to exploit small advantages in the long term and long term plans in general. I would like it to have as much exercises as possible. What would be a good book for this?

I am rated around 1800.
There are two new and well received books in that direction:


Winning Chess Manoeuvres 
Chess Structures


At least the latter contains 50 exercises as well. 

Strategic Play by Aagaard is very close to your specifications, it contains a lot of exercises and is pretty much about 'the long plan'. Unfortunately it's extremely difficult. (I gave my book away to a friend, who is close to his last GM-norm).

Positional Play is much easier, but still tough for an 1800 player. And of course the focus is more on correct piece placement and the like.

And Techniques of Positional Play is supposed to be quite good as well.
