I love these common mistake series. I learn a lot from the explanations and examples why those moves are wrong.

Well I'm 5 kyu (ostensibly) and I still learned something here (with the reason for three-space jump in the last joseki). So thanks!

I am working through most of your videos. And thank you for the clarity and validity of what you say. However. This is not really 20-30k level - it applies beyond that level, for sure. But this is a minor point - the material is what matters and it is great food for thought.

I do not trust AI blindly, and I know very little about joseki, but I want to bring up that I loaded all positions to katago (after filling all 4 corners) and it disagrees with considering the 2-space extension at 5:40 to be a mistake.
Katago says the 2-space extension loses about 0.3 points, and the 3-space extension loses 0.5 points (and for the 3-space extension, the kick-nobi exchange loses 0.6 points for the kicker)
OGS' joseki dictionary also says tenuki and the 2-space extension are currently preferred by professionals over the 3-space extension. This doesn't prove it's better but if professionals play it then it can't be a mistake right?

I noticed after the attach and hane, you alter how long the cut protection should be. is the longer cut protection okay because you created more liberties by pushing into the corner and making an iron pillar?

at 3:30ish, why does B4 prevent black from kicking C5?

[felderosa]

I'm 9k and learned a lot in 6 minutes here!
