What do you think of this course? I liked it. I sometimes forget chess is about taking over key spaces.

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.

GM Patrick Wolff's courses are astonishingly good on this platform.I am finding these demonstrative tactics far easier to find in my own games.

Sadly other thousands of courses and lots of time on other trainers just dont compare to these.

Great info.  I will these.  I have been working through endgames ... a part of the game I just never paid much attention to .
