It is filled with rich positional possibilities and nuances that one should be aware of. I have tried to show as many aspects as possible, pointing out exactly the relevant details and knowledge that are normally only accessible to strong positional players, such as Kramnik.
This opening is for fans of classical chess. I wanted to present chess in the "old" style, before players had access to engines to help them with their play and understanding. Before engines, players such as Colle and Zukertort created and innovated to such an extent that we still use their ideas today. I wanted to use this approach, to remind readers that this style of chess still exists.
