Very cool. I’m using this to help a (adult) friend of mine learn to play as she seemed rather intimidated when I showed her an example of a full goban. She seems to like it.
I think I found a mistake in lesson 5. One of the slides reads: “White will lose the stone at A if Blue plays at B, so Blue adds a stone there to form a new group.”
I’m pretty sure it should read: “…so White adds a stone there to form a new group.”
It’s White’s stone at B, not Blue.
Otherwise, I’m looking forward to what lessons 6-8 are all about. Oh, one additional comment was made by my friend:
“I’m not grasping why some moves arent allowed (self capture is obvious).” I would guess she found a ko somewhere but I’m not sure.
