The OGS Joseki Explorer now supports “forward arrow” (thanks @anoek for the merge!)
This will take you again through the way you went the first time, if you have come backwards using back arrow.
If you haven’t come backwards, it will take you forwards through the “best” move sequence (as per the variation label numbers: chosing ‘1’ each time).
It has one bug: it can’t go fowards through a “pass”. If you do that, it will place a random stone instead of passing, and you’ll need to reload the page to get things straightened out. I’m working on fixing that!
