Why not take advantage of your diamond membership and do some lessons? There is a really well written 5 part series on openings in the study plan. Since titled players wrote the material, it's bound to contain better advice than the average response in the forums. Still, you might want to check out some of the previous forum threads on the subject. Here's a few pages of links:

THank you!, I will check out the study plan first
For someone seeking help with choosing openings, I usually bring up Openings for Amateurs by Pete Tamburro (2014).

https://chessbookreviews.wordpress.com/tag/openings-for-amateurs/
I believe that it is possible to see a fair portion of the beginning of Tamburro's book by going to the Mongoose Press site.

Perhaps thegrinder50 would also want to look at Discovering Chess Openings by GM John Emms (2006).
"... For beginning players, [Discovering Chess Openings] will offer an opportunity to start out on the right foot and really get a feel for what is happening on the board. ..." - FM Carsten Hansen (2006)

"There is no such thing as a 'best opening.' Each player should choose an opening that attracts him. Some players are looking for a gambit as White, others for Black gambits. Many players that are starting out (or have bad memories) want to avoid mainstream systems, others want dynamic openings, and others want calm positional pathways. It’s all about personal taste and personal need.
For example, if you feel you’re poor at tactics you can choose a quiet positional opening (trying to hide from your weakness and just play chess), or seek more dynamic openings that engender lots of tactics and sacrifices (this might lead to more losses but, over time, will improve your tactical skills and make you stronger)." - IM Jeremy Silman (January 28, 2016)

"... Overall, I would advise most players to stick to a fairly limited range of openings, and not to worry about learning too much by heart. ..." - FM Steve Giddins (2008)
"... Once you identify an opening you really like and wish to learn in more depth, then should you pick up a book on a particular opening or variation. Start with ones that explain the opening variations and are not just meant for advanced players. ..." - Dan Heisman (2001)

"... To begin with, only study the main lines ... you can easily fill in the unusual lines later. ..." - GM John Nunn (2006)
"... I feel that the main reasons to buy an opening book are to give a good overview of the opening, and to explain general plans and ideas. ..." - GM John Nunn (2006)
"... If the book contains illustrative games, it is worth playing these over first ..." - GM John Nunn (2006)
"... the average player only needs to know a limited amount about the openings he plays. Providing he understands the main aims of the opening, a few typical plans and a handful of basic variations, that is enough. ..." - FM Steve Giddins (2008)
"... For inexperienced players, I think the model that bases opening discussions on more or less complete games that are fully annotated, though with a main focus on the opening and early middlegame, is the ideal. ..." - FM Carsten Hansen (2010)
"... Everyman Chess has started a new series aimed at those who want to understand the basics of an opening, i.e., the not-yet-so-strong players. ... I imagine [there] will be a long series based on the premise of bringing the basic ideas of an opening to the reader through plenty of introductory text, game annotations, hints, plans and much more. ..." - FM Carsten Hansen (2002)

"The way I suggest you study this book is to play through the main games once, relatively quickly, and then start playing the variation in actual games. Playing an opening in real games is of vital importance - without this kind of live practice it is impossible to get a 'feel' for the kind of game it leads to. There is time enough later for involvement with the details, after playing your games it is good to look up the line." - GM Nigel Davies (2005)
"Generally speaking, 'Starting Out' and 'Sicilian Najdorf' are not exactly words that one envisions in the same title, because anyone who is just starting out should not dive into the vast ocean of theory that is the Najdorf. For beginners, the time invested in studying even minor lines can be more productively used solving tactical puzzles and basic endgame technique.
...
... In some lines, a good understanding of basic principles will take you far, while in others, such as the Poisoned Pawn (6 Bg5 e6 7 f4 Qb6!?), memorization is a must, as one wrong move can cost you the game in the blink of an eye. ..." - FM Carsten Hansen (2006)

"... one simply cannot play the [Najdorf Sicilian] safely without studying the complications and remembering a lot of concrete variations. If you are averse to doing this, or you have a poor memory, you are better off avoiding such lines." - FM Steve Giddins (2003)
"As a professional player, I participate in many opens. I need at least 7.5/9 for the first place so I have little margin for mistakes. ... It suffices to mention the 6.Bg5-attack with forced variations all the way up to move thirty or more, to understand my reluctance to use the Najdorf. ..." - GM Alexander Delchev (2006)
You like open lines you say...?
For white there are a lot more choices as you know what you're playing
-Scotch: e4 e5, Nf3 Nc6, d4. opening the center up fast and likely ended quickly at your level due to tactics and shenanigans. White can even sac a pawn for development, planning to win it back later.
-Danish: e4 e5 d4 exd, c3 dxc, Bc4 (Or nf3 works alright too) cxb, Bxb2. You have two pieces developed for two queenside pawns, and if you play Bc4 like me you have quite scary control of the board. Danish is riskier than Scotch, but i find it leads to more exciting games for me and thus is my opening of choice.
-Bongcloud: e4 e5, Ke2. Believe it or not, bongcloud isn't that bad. The derivative lines, such as the bongcloud gambit (...Nf6 Qe1 Nxe4 Kd1) usually destroys the opponent's repertoire and gives them a good scare, if not anything else.
-Halloween gambit: Four Knights game, then Nxe5?! Follow with a bunch of pawn pushes on opponent's knights, somehow win.
...ok, don't play those last two unless you want to. Start with Scotch if you like open, but not reckless games.
Hello! - Has anyone got any advice on how many openings should be part of my repertoire?
As only rated 1100,i was thinking I should keep it small?, for example as White I always try begin the Itaian Game.. and take it from there..
As black I often get caught out which defense to play, especially when D4 not E4 is played!.. ive kind of learnt the najdorf variantion of sicillian, but is that to advanced to be considering for my rating?
I like open games more than closed ones! - ive even looked at the kings gambit but didn't have great success!...
Im kind of hoping someone may be able to suggest a list of 3/4 opening main lines I should learn... ?? Anyone!?
I'm currently working through tactics books, and also an endgame study, Im really conscious of my weakness in the opening!... Help!!!?
