graded problems prime your mind, February 28, 2010 By Jeremy Waterman

Ok, there are lots of problems here, but I wanted to note one particularly unique aspect of this series that I find excellent:
many of the easier problems are actually subcomponents of later harder problems. You can drill the easier problems, which helps you see parts of more complicated problems easier! This helps prime the mind to better know at what depth you can stop calculating, as you've drilled the end part more, such that simply getting to that previous starting position is enough. Not all problems are this way, but they are sprinkled in, and really help boost confidence in solving complicated problems easily.

One complaint I have is that too many of the problems are mate oriented. This is such a relatively rare component of chess (certainly important to study though), but I'd expect closer to half the problems to be material gain oriented, when it seems closer to 10%!

The variety of positions is excellent, usually quite double-edged (where many of these tactics are most important), material is usually equal. Just thought I'd put a few more comments in there.
