Depends - What do you do with c4?
Do you always play the same moves no matter what, treating it as a system? If so, not good!
If you treat it as a true opening with a willingness to deal with transpositions, then it's fine.
For example, after 1.c4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.Nf3 Nf6 6.O-O O-O, there is nothing better for White than 7.d4, which will usually end up transposing to a Fianchetto King's Indian Defense.
Also, do you actually know the ideas? The exceptions? Etc.
For example, after 1.c4 e5 2.g3 Nc6, 3.Nc3 is necessary as 3.Bg2?! f5 4.Nc3 Nf6, White has NADA, ZILCH, NOTHING! Instead, after 3.Nc3!, 3...f5 should be answered by 4.Nf3! (NOT 4.Bg2?!, see above) Nf6 and now 5.d4!!, answering 5...e4 with 6.Nh4 (which can't be played if your Bishop is already on g2) and if Black every tries to drive that Knight away with ...g5, then the Knight goes to g2!. Attack g5 with h4, inducing ...g4, and you have a great outpost on f4 for the Knight. Despite playing 2.g3 here, The Bishop should be developed classically in this line to either e2 or d3.
Cambridge Springs can't be pre-meditated. You better have something for the Exchange QGD and the Catalan. Otherwise, your Black repertoire should be ok.
whats your opinion over my opening repertoire
as white i play c4
as black in e4 i play french defence
in d4 i play cambridge springs
