Hi! I just published the first two volumes of The Tactics Ladder! It has been a project that I have worked on since last spring where I got the idea. It is special to publish a series of puzzles selected by specific criteria set up by me and based on data (user-ratings and themes), but not to have worked through them several times as I have done with my other books. However, I’m impressed by the puzzles I have looked at while setting up the book, so I’m confident that the selection method brings forth interesting puzzles.
Thanks! Just bought paper copies of the two books. I am looking forward to working with them.
