I'm on my phone right now so I can't check easily but if you aren't on v3 of the site you might check and see if you can do more at a time there. I doubt you can, due to server load issues, but I could be wrong.
I think you will still be limited to one page at a time. Premium only guarantees access to your whole archive, not the ability to download them all at the same time.
I normally grab my games shortly after completion and insert them into a SCID vs PC database so rarely have the need to pull down large numbers of games.
How can I download all my games?
I am a premium member, yet I only can get one page at a time from the archive, which is tedious for 8k games.
I want to get them all.
If anyone knows a way to automate it, please message me or post here. I couldn't find anything via search.
I also want to somehow build a database of all my PGNs/games, in order to see how I've done with particular openings.
Sadly, this site doesn't seem to support neither examining how I've done with the openings (the Game Archive doesn't show my games properly), nor the automated download of my games. Which is exactly what I wanted a premium membership for. :(
Oh, and, any ideas/tips on how to do any of it are welcome!
