Great question! The best book is Andy Soltis' How to Choose a Chess Move. There's just no way to get around "choosing candidates" and "building trees".
A bit harder, but still excellent, is his The Inner Game of Chess: How to Calculate and Win.
I find Silman's books to be overly simplistic, esp. since some of his exercises meander into deeper, darker territory that are outside of the scope of his little "strategy lessons".
What are, in your opinion, the best books about thinking methods or chess psychology? I mean, not book about knowledge, but those that aim the reader to put effor in how to choose the best moves.
thanks.
