Classical Chess Opening Repertoire I decided that I want to learn classical chess.  Although I'm rated in the 1400's, I want to really gain a strong understanding of basic ideas and principles in chess and improve my tactical ability.  Thus, I want to generally go for open games.  I also don't want anything theory-heavy or complex.  Just nice, simple, classical/traditional openings and/or openings that involve playing with the innitiative or defending against the innitiative that will are good for learning and also viable at the top level.  So the opening repertoire I'm going with now is:

As white:

1.e4 

Versus Sicilian Defence: Alapin Variation

Versus 1...e5, Four Knights Game (regardless of 2...Nc6 or Petroff)

Versus French Defence: Tarrasch Variation which will either lead to the Rubinstein Variation or 3...Nf6, after which I'll try to get into the Nunn-Korchnoi Gambit

Versus Pirc/Scandinavian/Caro-Kann/Alekhine/Modern: I'll just play relatively main lines and/or develop by opening principles.  

As Black:

1...e5

Versus King's Gambit: Decline with 2...Bc5
Versus Danish Gambit: Accept and defend the best I can (after I get destroyed, I'll probably look up how to do it)
Versus Italian Game: Giuoco Piano
Versus Scotch Game: Main Line with 2...Bc5
Versus Spanish Game/Ruy Lopez: Classical/Cordel Variation with 3...Bc5 
Versus Ponziani: Dish out that relatively brief line I learned yesterday from the FCO so I don't get destroyed again 
Versus Four Knights Game: Play symmetrically and/or develop with opening principles

Versus 1.d4, TRADITIONAL QUEEN'S GAMBIT DECLINED - not the Lasker Variation, but the one where you fianchetto the light-square bishop.  

Is this a good learning repertoire?
That opening repertoire looks good to me. However, I must warn you about over-focusing on opening theory at your rating level.

Right now I am going through a phase where I am focusing on other areas besides opening theory.  Some of the old masters, such as Lasker, didn't even bother with it.  Although I'm not sure if he would get away with that today.  I do think that a lot of lower-rated players focus too much on opening theory.  In most of your games, opponents aren't going to be playing the books moves, so it may actually be a waste of time to learn a bunch of opening theory. Instead it may be more beneficial to REALLY learn a solid set of chess principles, and even more importantly patterns.
