布石では速さと展開が最優先ですが、中盤に入ると重心が移り、碁盤の上で主導権を争う石の一団同士の、込み入った舞へと変わります。十分に鍛えれば、絶え間ない猛攻をしのぎ、こちらから壊滅的な反撃を仕掛けられるようになります。これが中盤の熱狂、攻めと守りです!
コースの最後に、攻めと守りの導入となるボーナスレッスンがあります。始める前にご覧になることをおすすめします。

レビュー

The course was professional, well-paced, and free of unnecessary filler. I really enjoyed it and learned a lot from it. However, I do have one piece of constructive feedback. I think it would have been valuable to include more content about battles/combat positions, as this is where many important concepts and the practical benefits of both attack and defense become much clearer.
Excellent course. For this DDK, some of the material was a bit difficult, but I learned a lot, and the concepts and ideas were very well explained. I am sure I will rewatch the course at some later time and discover things that were over my head for now: there's so much to discover in this one course. Wonderful!
Really appreciate all the midgame theory in this course. Really helpful.
attack and defense is probably one of the biggest parts of a game of go so it's very useful to have to guide to approaching this topic
Good but a bit too advanced for me.
This course is a true gem. A&D is a very complex topic, but Chris boils down to several heuristics and mental models that are pedagogically transferable. He then takes you through examples while teaching other more specific notions (e.g. "shoulder hit the farthest stone", flexibility through sabaki / shinogi). The atmosphere, the philosophical perspectives, the Go equipment, all were excellent.
Very nice. Advanced basics
A very nice course. I can't say anything negative content wise. But maybe the rank recommendation is a little off. I think the chance is high that the higher sdk ranks of the recommended range know even the advanced stuff very good already.
Great content, Thanks.
Deals with difficult concepts and needs to be watched more than once.
I found this really helpful - interesting concepts, clearly presented. Problems that would have perplexed me before the videos seemed accessible after watching. Thank you!
Excellent course, well organized
Well done. Ty!
Great course from Chris. All looks plain and simple now.
Great course on attack and defense. I only wish there were more discussions and examples for me to consider.I will look forward to revisiting this one many times.
brilliant course with the exercises too!
Great course! Very well explained by Chris, thank you!
Simplifying all this for us to understand is impressive. Thank You Chris & team.One issue: Most of the quizzes were relevant enough that just watching the course was enough to solve them. Quiz 2 and a few others were especially tricky though. There were times I thought: "Ok, I understand this is the better move for this board but following the course principles doesn't take me here".
Best course so far. Great Topic and Chris is an excellent teacher, with very soothing voice.

Yo, very cool
