Not an especially easy read, but close study of the book will definitely improve the card play of the vast majority of bridge players.

The text is not all that difficult to navigate if one is at all familiar with the Greek alphabet and the scroll bar on the bottem of the Kindle screen. I have found it extremely helpful, even though I do not have a Ph. D. in Greek. For several months I did not purchase this based on previous comments about it being of no use on the kindle. I finally broke down and purchased it during a sermon at church. I could not have been happier with it. I am assuming the phd commenter was somewhat new to his ebook.
