I loved it. I've done a couple of GM Wolff courses now and they're GOLD. A few of the other courses I've tried seem more like 'phoned-in' versions of a chapter from someone's book, but his stuff always capitalizes on all the strengths of Chess Mentor as the platform - and the content is excellent.
What do you think of this course? I liked it. I sometimes forget chess is about taking over key spaces.
