A good Chess System for Beginners?

Well, I still advise you to view the opening as a more or less continuous learning experience, initiated by making sure that you know principles and then (from time to time) reading commentary on a few games for this or that specific opening (using your own games as a guide for where you might like to do a little expanding of the boundaries of your knowledge).
I wonder if you resist 1 e4 e5 because of this sort of experience:
I think that an author like GM John Emms (without taking up very much of your time) could go a long way towards helping you to avoid such disasters.
There are a fair number of people who think that near-beginners should not think at all about specific openings. Many of the rest would still disapprove of the quick-temporary-fix approach. Consequently (I suspect), there do not seem to be many books that try to help the near-beginner with QTF thinking. I have already mentioned Seirawan’s Winning Chess Openings as one such book. It occurs to me that Chess Psychology: The Will to Win (by William Stewart) might be regarded as another example. Every time I mention the book here, someone speaks out vehemently against it. You can see some negative commentary in the review.

If you are still looking for a QTF, perhaps it might be hoped that the book provides a quick exposition sufficient, for a little while, to help the near-beginner to get by in the opening while playing against other near-beginners.
