I recently received 1st 3 books of Aagaard's latest series
Grandmaster Preparation in the mail this weekend. I'm at not at a point
where I will be able derive the full benefit of these books, but I did
look through the introductory parts to see what GM Aagaard had to say.
One thing I thought was interesting was his training method for
developing intuition. He has a set of 3 questions (pared down from an
initial 9) that he has his students ask when looking at a position prior
to selecting candidate moves and analyzing.
1. What are the weaknesses? (potential targets)
2. What is the worst piece? (improve position)
3. What is my opponent intending? (prophylaxis)
For training ask and answer these before doing anything else and it
will help you focus on the proper things. Eventually you will do it
automatically without even thinking about it.
So while I am not ready to work through these books, I plan using
this training method immediately. My path to these books currently
consists of working through Yusupov's 9 volume set, Aagaard's earlier
excelling series for Everyman, his attacking and defense books, and then finally this latest series.
After that it will be time to take a crack at Dvoretsky, but that is a
long way off.
