Are most of the chess openings refuted in the Top level?

your for sure wron about the caro being refuted lol the most solid opening everrrr

      Openings are fashion that is mostly dictated by the World Champion. When Fischer was world champion KIA was in fashion.

When Kasparov was world champion Sicilian Najdorf was very popular. Today it's London and Berlin. If Caruana wins the championship the almost forgotten Petrof will suddenly become one of the most popular defenses. This is not unnatural. World champions often demonstrate  different ways of playing well known openings that  quite normally attract many good players.

    Then there is also the problem of engines. Finding a complicated line in Sicilian and prepare it with an engine is much more easy than in Berlin. Openings that require a lot of engine preparation quite understandably retreated in popularity and only the very few brave still play them.

    As Giri said :

"I can play against Anand but I can't play against Anand and his engine."

But all these matter only in top level. In all other levels everything reasonable(or even reasonably unreasonable) is perfectly playable.

The August 2018 issue of Chess lists the top twenty openings compiled from a list of 2415 May games where both players were rated over 2400 Elo. One can not take position on this list too seriously because it is greatly influenced by how the openings are grouped. For example, all the Retis are grouped together, while English is separated into 1...c5, 1...e5, etc. Nevertheless, for what it is worth, some of the list entries are: 181 Retis, 104 declined Queen's Gambits, 97 King's Indians, 95 Caro-Kanns, 89 Berlin Lopezes, 79 Nimzo-Indians, 70 Najdorf Sicilians, 68 Slavs, 65 1...e5 Englishes, 55 Catalans, 53 Petroffes, 43 1...c5 Englishes, 42 1...e6 Englishes, 42 1...Nf6 Englishes, 42 Giuoco Pianos, and 42 Classical Gruenfelds.

Wow, I never thought about that. It makes a lot of sense

someone to the rescue of my beloved caro pleeese lol

Yeah...latest info is that its out the door. Too bad. Even the top level players know....thanks to a TCEC game. Blame them lol.

woah. seriously?

They are fooling you . Caro Kan is pefectly fine!

True, I know nothing of the engine world but if you claim Caro Kan is refuted,  you know nothing of chess.

Caro Kan is fine!

I didnt stop playing it for no reason either! Its not that its not studied, its just all the study time is on white's side now. Too bad , it was a really good opening that the engines didnt diagnose correctly, at least at low processing power.

Also, I'm guessing that all gambit openings have also been refuted such as the King's Gambit, Evans Gambit, Volga Gambit etc. Although GM Adhiban Baskaran from India drew against Wesley So with the Kings Gambit in a classical game during the 2017 tata steel

nighteyes suffers from delusions: In another thread he somehow discovered a refutation of the Dragon with the "Stockfish attack" while in reality it was just a very common line, known since decades, way before engines were invented, and GM Gawain Jones happened to have forgotten the theory, and got crushed.

I guess he has now abandoned the Caro Kann (if one assumes that he has ever played it!) because of another, similar delusion.
