I recently bought Artur Yusupov's "Build up your Chess" series, both as a resource for when I coach, and as training material for myself. One chapter (from volume 1) is titled "Centralizing the Pieces" and covers the importance of having strongly posted pieces in the middle of the board.
The example game he gives in the chapter is Pillsbury v Marco 1900, which I have seen in a couple of other books as an illustration of a strong knight on e5. Pillsbury's treatment of the Queens Gambit often saw him play Nf3-e5 and support it with f4. If Black exchanged the knight the White would have both a cramping pawn on e5 and an open f file to work with. Yusupov refers to this as 'posting up'.
It is still a plan that can be used with great success even today, as this game played in the KL Open last month shows.
