What a fantastic course. Professional and clear, it's obvious that a lot of effort has gone into making it. Highly recommended. As well as providing clear opening lines, this course also reinforces the ideas and the chess principles behind those openings. The course doesn't simply provide opening moves to be made automatically, it presents idea behind the moves, what the immediate threat is and what the goal is. Most importantly for me, it shows how deviations in the opening are not necessarily to be feared, reducing my panic when I see my opponent play something unexpected.
