How to find the name of an opening by the moves


Thanks a lot. I knew I wasn't the first person to think of that. :)
You have a wonderful collection of information. I appreciate the help. Now I can see what hole I fell into a couple games ago.


Believe it or not, another good reference is just a generic web search. Go to google or some other search engine, and enter the moves you want to know about IN QUOTES, ie "1. e4 e5 2. Nf3" and click "search". Not only will you find out the name and ECO code for the opening pretty quickly, you'll also find lots of complete games that begin with those moves, which you can study to get a feel for how to play that opening. You'll often find games that start with those moves, but one player or the other varied in a way you wouldn't expect. So you get a more realistic view of how the opening is actually played in the real world than just studying the "book" moves recommended by grandmasters.

Thanks for all the posts. That really helps. I went from thumbing through a book and maybe finding it to this vast land of opening information.
Thanks to all of you.

A cool website that... er, is hard for me to explain right now. But check it out.
1. c4 Nf6 2. Nf3 c6 3. g3 d5 4. Bg2 Bg4 5. O-O e6 6. d3 Nbd7 7. cxd5 exd5 8. Nc3
This position can be arrived via more than 100 different move orders. I have found at least 4 different ECO classifications: A07 Reti KIA, Keres Variation (scid) /A11 English Opening 1...c6 (chessbase)/ A15 English Opening Anglo Indian defense, King's night variation (lichess)/ A08 Kings Indian Attack (lichess) / A07 Reti New York and Capablanca Systems (chessbase) / A07 Reti King's Indian Attack, Yugoslav Variation (365chess.com). Of course all of the sources classify this opening with different names depending on the move order.
So how do I find out the correct ECO classification?
Some openings I play I know or can find easily the name. Then I can find out about them. Others I cannot find. Is there a place that lists them by the moves so you can just look throught all the 1. e4e5 2 nf3 possiblilies and so on.
Another post told how to find the info if you know the ECO code, but my problem is I have only the moves. How do I translate that into the ECO code and a name.
