Best defence against e4

i do not think the scandinavian is a bad opening i just merely find it unambitious and uncreative. you rob white of what they would normally like to do which i suppose is something.

i am just an intermediate player but i have no trouble with the scandinavian. one thing every scandinavian player at my level loves to do is pin the knight after Nf3. this is annoying. while not the best move according to the engine playing h3 on move 4 disrupts this plan and still maintains advantage for white. it is often the case that the scandinavian player will go into an unusually long think after this move because Bg4 is what they always play and now your knight can move freely. i cannot remember the last time i lost to a scandinavian. mostly i lose to sicilians.

Against Reti I play d5.

Against English I play e6

Against the Queen's Gambit I play Nf6

Against e4 I play Sicilian Defence

I play the Queen's Gambit.

Why play a bunch of openings when you can only learn one?

Then don't expect growth. Passing on to the study of another opening without finishing the first one is complete nonsense.

No you can study a l l at the same time

But tell me why? So that later there was confusion in the head and during the game the options were confused? And in general, few people have time to learn all the openings.

No bro its about more option and verstaility you have 

Like I explained above how much verstaility with white pieces I have with 1 d4

Ya this is true for only otb in online your opponent is anyway playing you first time 

Yes

What do you mean? Why? I don't understand you at all...

I was saying that you should learn 3 opening for flexibility I  prepared the theory of queens gambit , catalan and Trompowsky and now I love playing d4 as I know what to do when opponent plays certain move or I can find out the inaccuries and weakness in the move which are not given in book

Flexibility in sense is just let's take a example against 1 d4 nf6  I can go for samisch variation if he plays g6 Or neo grunfeld if he goes g6 d5

Or I can play catalan Or if in mood can go for surprise with 2.BG5 Transposing to Trompowsky this is what flexibility means

As though the Indian-opening complex is easier.

Ahh, it's all clear now.

But personally, when I played e4, and d4, and c4, there was no growth. And in the end, I still played only d4. Well, for a while I only played c4. Therefore, I do not understand why this is needed, and the meaning.
