Wow! I've speed run most of this course and I'm really impressed. The puzzles are really well organized, the patterns are named, the relevant sub-variations are also included. I also don't remember having any valid complaints about soft-fail alternatives. This is a course worth doing multiple times, and despite most of the puzzles being easy for me, I plan to drill this course - getting the basic archetypes down cold sets a fantastic foundation for acquiring more complicated tactical patterns. Highly recommended!
