Chess Opening Database

Where could i find a chess opening database for free?

I dont want something like Games explorer.

The only other online option is chessgames.com, though you have to pay to get beyond move 4-5 of most openings in their flavor of the explorer.

Of course, off-line tools exist as well. Download SCID (a free database software that attempts to rival Chessbase).

You can either make use of its opening book by opening the "book window" and seeing the main lines of theory, or if you'd prefer over-kill, overlay this with a reference database window to see what has been played historically.

To get reference database set  up for SCID, google around for a nice big scid-base or convert a big PGN-base (which will take a little time, but it's worth it).

Now with all this being said, nothing beats commercial grade software like Chessbase ... and if you can find an older version in a bargain bin or on ebay you'll be set as well.

Hope this helps!

If you don't want something like Games explorer, what do you want? What about the Opening Explorer, here?

I find that Wikipedia has many openings, and it's free. Although it can be somewhat hard to understand, I have used it a lot to develop my games
