Books and Opening

I'm not good with books and I'm only familiar with a few opening/books like King's Pawn Opening and Queen's Gambit.

What are some good books/openings I should try? Why? 

I do Van't Krujis Opening because I feel like it is secure and I always win with it.

I also suggest Scandinavian Defense and King Francietto's

Buddapest gambit agisnt D4 , and italian game (fried liver or lolli attack) as white.

Van't Krujis is bad, thats why your 800.

Am opening choice doesn’t make the players rating, the skill level does, until people know how to take advantage of it

Maybe, but the openings he is talking about arent good, the scandinavian is better for white (grants white a tempo on the queen if qxd5) (im also aware of  2.nf6 after exd4). and the Van't Krujis blocks the queen's bishop.

Excuse you, I play the scandi <3

and I know a 2400 blitzer that plays e3

I dont know much about the scandi, I have played the main line serveral times but thats about all.

when I saw that sockfish gave white +1 in the scandi, I stopped playing it.

*sighs* 

lit really isn’t that bad 

I did a little research on Van't Krujis Opening and it looks like that white is in a bad position

I like to control the center

Edit: I don't like how the knight is blocking the queen's and the bishop's attack. 

Queens gambit is good

A 2400 Blitzer and a legit 2400 player are NOT the same thing.

It is NEVER played as anyone's mainstream defense to e4 at the top level.  Every once in a blue moon it is used as a one time surprise weapon (World Championship 1995, round 14).

The Scandinavian is significantly weaker than 1...e5, 1...e6. 1...c5, or 1...c6.

I know, I’m just saying it isn’t horrible

and experience sometimes in an opening slightly inferior is better than playing something normal that you have no idea how to play, and it isn’t too hard to equalize as black in scandi when your opponent doesn’t know enough theory

(once again) Iitalin, becuse it's an easy opening to learn

First, forgive me, my English is too bad to express clearly

I don't actually try to remember the opening/books, I only remember some moves that may be moved often, that's why I do Reti Opening.

Actually, if you're not good with books, you should try as many opening as you can at least 1 time, and find the opening you feel good yourself, that shows more factual than a suggestion.

Dig deeper on what you want, if you really want a suggestion, I'll suggest Reti Opening, for 3 reasons:

1: I love that opening

2: Reti Opening has tons of variations, also includes Queen's pawn opening system, King's pawn opening system (not King's gambit).

3: Although Reti Opening has tons of variations, but you can easily make proper move with opening principle and common opening move.

Dont many Reti's transfer to other openings?, just in a different move order? like it could turn into a two knights caro-khann

A lot of players suggesting offbeat openings. As someone who has used them all the way from 1100 online to 2300 online, from 800 uscf to 2000 uscf - 

you will STILL HAVE TO STUDY! I cannot emphasize this enough. In the long term, as long as the opening isn't complete garbage, the total amount of study done is less. But at the beginning stages? You will have to learn a lot more about the opening than any conventional and reasonable opening. 

The Budapest Gambit is probably one of the worst offenders of this. You have to know a lot of lines to get a reasonable position, and the positions are very reasonable for white (I used to play it).

Openings like 1.e3 are fine - as long as you transpose into some reasonable setup. But wait!! you need to know many different setups! And there is the problem.

Very specific openings are also not good for your chess - specific gambits such as "Fried liver" and the like. Learn the italian first-  then learn the fried liver. the chance of getting them is low, making your learning time worthless.

I would recommend some simple stuff - usually exchange variations are quite sound and quite good. 1.e4 - ruy lopez exchange, caro kann exchange, french exchange...

Italian is fine, and it is what I used to play - but I feel like there are too many traps and gambits that people can look up in there. And you would be wasting your time trying to find counters to them all.

The scandinavian is a perfectly fine weapon against 1.e4. While it's not as theoretically challenging, it does narrow white's options quite a bit and there is no way the mainline is +1 for white.

I play the czech benoni as black against d4. I have beaten players rated over 2100 USCF with it in classical (60+min) games. After five moves - white is +1.5 according to chess.com's browser based stockfish 14 (depth 20).

It has not stopped me from winning my games.

van't krujis is not "bad" in the sense that it loses or gives a large advantage to black immediately.

GM Axel Smith, author of the "woodpecker method" and "Pump up your rating" (I have this book) wrote a book about 1.e3 - "e3 poison".

Is there a digital copy I can look at?
