A chess game is like a movie: if you begin in the middle of it you have to make some effort to get into it. So when you examine a position you should begin in exactly the same way. First you take a ‘global’ look to get some general information
and then you will progressively focus more deeply. What impression does it give you ? Once you begin to get involved with calculation you will not be able to retrieve this fresh look anymore – which some people call ‘intuition’.
