I lost a game today because of a really simple misread on a L+1 corner group which reminded me that I never really bothered learning all of the common corner groups and refutations because I am super lazy. So now I want an easy way to study and review these common shapes by making a set of go problems starting with L shapes and variants and then moving on from there. Essentially, I want to turn the L group page from sensei's library into an interactive learning experience.

Is there a tool to use where I can create a library of go problems in a single interface? Ideally, I would want something where the program would choose a variety of responses to prove that you know how each move works. Is there such a tool, or am I getting way ahead of myself and should just make some flashcards?

IMX, constructing problems can be quite educational. I think that making your own flashcards is something that you would find helpful for your learning, especially if you work from memory. Good luck!

Hello DJLLAP,

That would be very interesting and helpful, for many of us.
First thing which springs to my mind is Eidogo, perhaps you can use it? I understand it is open source and can be embedded in your own website.
Maybe Justin Kramer of Eidogo would be willing to be of assistance?

Good luck!
