Opening for white??

I was playing the italian, king's gambit,

And the jobava or normal london

Without knowing why you're dissatisfied or what you're looking for it's hard to give recommendations.

I didn't like e4 because there are so many things that black can play like sicilian, caro and anything else. And I enjoyed the london but I thought that system openings will not make me improve fast.

jobava isnt a system opening and the chigorin repertoire is compact, why did you reject it?

Was the problem with e4 the size of the opening, or the preparation of black combined with the size?

Maybe take a look at the English opening. It may be a large opening but at least black won't be overly prepared, you can avoid d4 transpositions if you're careful... HangingPawns has some good videos on youtube on the english.

If your problem is the openings size ... e4 is generally more forcing, there's not much better if you want to minimize the size of the opening. Except maybe the Jobava or Veresov. Or some very early gambit like the blackmar-diemer.

If just size is the issue, seeing as you've decided against the Jobava you may just stick with e4, but try to find some early forcing sidelines against blacks other moves... Like against the sicilian play various 3rd move b4 wing attacks, or something like that (2... Nc6 3. b4 is especially good). Against 1... e5 still play the kings gambit. etc. Against the caro-kann try the blackmar-diemer transposition. Against the french... 2. b3 the horwitz attack is an interesting line, there's also 2. c4 the steiner variation.

Against the Pirc I'd recommend the Byrne with an early e5 push.

If improvement is your goal try experimenting with different defenses to e4 as black, like the alekhines defense.

Thanks for the amazing recommendation! I really appreciate it

I think I will stick with e4

@1

"I wanna change my white opening repertoire" ++ Each time you switch openings you lose more. It takes time and losses to accumulate experience.

"I play kid and dragon for black" ++ Then King's Indian Attack or English spring to mind.

@2

"italian" ++ Great
"king's gambit" ++ Not so great

@3
"And the jobava or normal london" ++ Good

@5

"I didn't like e4 because there are so many things that black can play" ++ That is with any opening

"I enjoyed the london but I thought that system openings will not make me improve fast"
++ Improvement has to do with tactics, not with the opening.

@8
"I think I will stick with e4" ++ Wise decision
