Opening for white, intermediate level (1100 - 1600)

I'm around 1000 on chess.com, though I do feel that I'm underated since I do beat my 1300 friends, and I want a good opening for white for blitz and bullet against either e5 or just a totally new opening. I've been playing the king's gambit for fun however I'm realising now that I need to know some theory for instant moves. I could learn king's gambit theory but I might as well learn something good. The Italian and 4 knights is too boring for me, the English I use for rapid and d4 for me is just out of the question for me at this level. I'd also preferably like an opening not many people know, relatively, like the king's gambit and etc.

Also for line 5, I don't mean against a new opening, I mean with one like d4 or C4 etc

I would recommend the evans gambit.

Learn the London

If the Italian is boring for him, absolutely not the London

I recommend the Ruy Lopez. It’s a great opening at all levels, can be very tactical, and the plans are clear.

Most of these lines are incredibly dynamic and fun to play.

Sadly, almost nobody knows how to play openings, so they’ll play 3… d6. I recommend this:

You have a solid position with tons of space.

Btw, you HAVE to study the Marshall. You’ll get blown off the board if you don’t do so. The Marshall is arguably one of the best responses against e4 for black.

You can try 1. Nf3,... it could transpose to anything. But, if black responds 1...,Nc6 then 2.e4,e5 3.c3,... and you are in the Ponziani.

Or 3. Bb5 and you’re in the Ruy Lopez but who am I to judge

The London does have a few attacking ideas after the opening, its like any opening no one has fun in the opening. but the middlegame is the most fun part in chess overall and the london is no exception

the middlegame’s fun if you know what you’re gonna do
I do not know what to do here. Improve the position of your pieces? How? Black has too much space for you to do so.

You know exactly what you want to do here. Move your queenside knight to the kingside, take on c5 in the future to open up the position for your rooks, and place you bishops on active squares eyeing the kingside. Then, you’ll have a fantastic position.

Learn your middlegame plans, Robert Ramirez and coach kestony posted videos about them

I’ll check them out

Also forgot to mention this but if you want to learn an opening you need to know ur middlegame plans, its necessary

yeah that’s true

Also try out and read Alex banzeas london course. There is a short and sweet

The Polish is pretty much the perfect intermediate blitz weapon. Learn the theory and just win, win, win

Evans, Scotch, or Vienna Gambits?

First of all I’d recommend not playing bullet in the first place, as you don’t really learn any useful chess skills from it. Also, this whole “unknown opening” stuff… doesn’t work. EVERYBODY avoids theory like the plague so they’re more likely to know your BS line than they are to know well-known mainlines.

Anyways, why not just continue playing the English and make it your main repertoire and why is d4 off the table?

If Black responds with 1. ... Nc6 then you play 2. d4 and just roll him off the board (unless he's a big fan of the QGD Chigorin).
