Opening repertoire trainer?


Chessable actually does allow custom courses so that you can enter your own repertoire and drill whatever lines you choose. It's pretty much 90% of what I use chessable for nowadays. You can even do it with a free account, no need to spend any money.
For anyone google searching for this, chesstempo has a very good opening repertoire trainer - even for "free" members. You can store double for a few dollars a month. C'mon Denny - get one over here.

Hi,
I developed a tool which is available to help you build, maintain and memorize your repertoire.
It's a free web application, no ads, nothing to download, mobile friendly...
