New Blindfold Book Series

Philidor playing blindfold chess.

I have decided to make another series of blindfold training books. If you do not know I have published two blindfold books so far: Blindfold Endgame Visualization and Blindfold Opening Visualization.

However, after solving some good mate-in-two problems blindfold I thought why not utilize the work I did with the large mate-in-two database I worked on earlier in the year to make a blindfold-mate-in-two-problem-workbook-series?

Here is an example problem:

VOGEL Peter, 1999
♔b6, ♖c7, ♘a7
♚a8, ♝b7
White to move  

But before I go on I would like to ask you some questions. My idea is to make the workbook series include 3 books with rising difficulty levels (Level 1, Level 2, Level 3). The above problem would most likely be in the level 1 book.

The thing I would like to ask you is, how many problems would be manageable and good value for you if a book costs §9.99?

Also, I would like to get some ideas from you about how the book cover could look like. So if you have a brilliant idea, please drop a comment:

As always paid subscribers will get the ebooks for free, so consider upgrading your subscription and support my little publishing house.
