The Livshitz "Test Your Chess IQ" series is like what you want.
Each test is a set of 8 positions, and you have a certain amount of time for each set. Sometimes more than an hour per set. There is some motif for each set of problems but finding the solution can be devilishly hard.
They are not a pattern recognition series of problems but rather a test of board vision and analytical powers, while being mainly combinative in nature.
There are 3 books in the series. I have done 1 and 2, and I found the 2nd book to be a fair challenge for me (max barely 1800 USCF).
There is a provision to compare your accumulated score and find an Elo equivalent. It gave me 1750. The first book was the easier test and I scored maybe 100 + points higher. The 3rd volume is Grandmaster Challenge and is supposed to be quite hard.
Hello Hive!
I'm asking the well-read players out here to recommend a chess book that really drills one's analysis skills. Not mate-in-X puzzle books or tactics books that "broadcast" the fact that there is a awesome move waiting to be calculated out.
Just exercises with positions that require intense sit-down-and-calculate efforts to find the best move (which is not going to be a tactic).
My goal is to compare my analysis with some reference source to see what I missed.
One example I've been going through is Cheng's Practical Chess Exercises. Any others?
