I don’t really know what I’m talking about here, since I thought that https://online-go.com/joseki/5613 was a slack move to begin with – which it apparently isn’t – but I noticed a couple of things.
On https://online-go.com/joseki/5608, there is as much play for simply Q14 as there is for cutting. Both the cut and the extension have been seen in a number of pretty open positions and I can’t say I understand the choice of one or the other.
One step down the line, on https://online-go.com/joseki/5612, there seems to be as much support for S17 as there is for the marked atari.
I have to emphasise though that I don’t understand these positions. I thought that https://online-go.com/joseki/32126 was the only way to play.
The datasets we’re working with at this level are also a bit small.
It’s great that you’re checking these. As you go, make sure you check the end positions, too. They often have sources that help explain where the position comes from. These positions apparently come from Bozulich - Get Strong at Joseki 2, and so the reason they’re in the dictionary and other equally common moves aren’t is that the author discusses only the former.
(NOTE: we’ve said that amateurs aren’t qualified, but it seems we’ve given Bozulich a pass because he’s written books about joseki, worked extensively with professional players and translated their works, and is the only source for many more obscure patterns)
@mark5000 I was just just adding them back at the beginning to help fill in the explorer while we were settling on the ideas I suppose.
I think it’s reasonable to replace the sources by professional players when they also show the joseki, or mark them as good or delete if that makes more sense for a given sequence.
