Ok; we want a chess opening that gives us a winning edge at the start of our chess game; particularly despite whatrever our opponent throws back at us.
Well :) life is not like that; we might want something but we are mere mortals and do not often get our wishes granted...
So, what we NEED from our chess opening is simple.
1) We need somtething we can build upon after learning the opening basic main line moves in less than a day,
2) It must not have a lot of sudden surprises from new and often found sharp lines that give others who have more study time an edge just by keeping up with new ideas always,
3) It should incorpate all the established guidelines of the openings principles such as developing co-ordinated activity and not exposing unnessary weaknesses,
4) Preferably it should not have a lot of detailed options to different positions; it should be solid and reliable,
5) Hopefully it should match your personality and style so you will work on this system for life instead of a few months and then swapping into another unknown opening,
6) It should not be regularly played "fashionable" openings means every one is thinking upon new move orders and how to use these openings; you do not want to play to others strengths,
7) It should not be part of a MegaGrandMasters (MGM) openings, MGM's have 'groupies' that religiously follow their ideas and even worse what MGM's play gets published ! you do not want this you want stuff others do not suspect,
8) An opening that is solid enough that SuperGrandMaster's (SGM) and MGM do occassionally experiment with it in high ranked games, this proves it is solid enough for these people to risk their rating, money and ruputation upon. So this generally means the rare and very rare openings are out, just because Larsen could win with 1. a4 does nothing to prove this is a solid nor reliable nor repeatable opening,
9) Whatever you choose will have certain weaknesses, but it should not have an easy obvious weakness that defeats it and makes your whole opening a bust...
10) It should have been around a long time so people have had time to learn it, prove it and FORGET it; so that when you pull out your opening weapon your opponent is going "what is this ? i recall this vagely from years ago " this gives you a psychology edge.
Above all; stay with your opening, do not swap openings unless a professional chess coach tells you to...
Learn it, play it and adapt to the common things your opponents throw at you...
Never try for rarely seen surprise weapons as your regular openings since they will help you reach a higher rating faster and then you will have wasted your time learning openings that serious players know how to crush; thats why you should re-read and follow my points mentioned above about the things your openings need to consider...
