Writing in english again is somewhat uneasy. I feel rusty both write- and chesswise. I did read a few old posts of mine. Especially this one caught my attention. I never really put the ideas from that post into practice. But pruning branches and excluding move orders based on reasoning about the initiative is a great idea. I will experiment with it. All other ideas failed, so there is nothing to loose.
I did a little test with solving an old high rated problemset. It turns out that most of the times I remember the moves, not the diagrams. Since the initiative is much more important than geometric patterns (see the old post I mentioned), it's logical to have a closer look at it.
Further I use a mind mapping tool lately, which is a great way to organize knowledge.
