Colle-Koltanowski Revisited

My  recent review of the Colle-Koltanowski System has raised quite a few questions.

(http://www.chess.com/article/view/the-colle-koltanowski-system )

First, I would like to thank all the readers who have offered feedback so far.A well-informed discussion is good for everybody.

A few words about the author:

Valery Bronznik is an International Master and chess coach with 20 years of experience.He is also the author of works on  other openings like the Tschigorin Defence and Sicilian Paulsen Variation. Recently he has written a book on technique in chess positions.All these titles are in German.Only the books on  Colle-Koltanowski and Tschigorin Defence have been translated into English.  

As for the book under review, I would still urge the readers to go through the Introduction readily available ( in pdf. file) from the publisher's site:http://www.kaniaverlag.de/htm/englisheditions.html

It would answer most of the questions raised in the comments posted on the review.

Here I shall deal with other specific points.

Question:Why does Black play  a move like...e6 instead of  actively developing the bishop to f5?

Answer:Let us take a look at the position.

Question:What if Black tries to play a line similar to the Tschigorin Defence here?

Answer:Here is a likely position.

Comment:The article mentions that after 1.d4 d5 2.Nf3 Nf6 3.e3 Bf5 white should play 4.c4. But after... c6 we enter a Main Line Slav which means that white suddenly has to acquaint himself with a different and important opening, which somewhat defeats the object of being a Colle player.

Clarification: " I would not recommend to you to use the Colle-Koltanowski setup against all the possible openings-you can get into a completely unfamiliar position where you will be desperate to find a suitable plan. But with some additional variations from other openings-according to the recommendations in this chapter-you will be well-prepared for the start of the game!"- Bronznik

Amen!
