Closely associated with the facsimile reproduction of Pacioli’s work, the book is the result of the contributions of leading experts in the chess-playing and palaeographic-linguistic areas who discuss complex subjects such as the historic profile of chess, the phases of recovery, the transcription of the manuscript, the attribution of authorship and the chess technique used by Pacioli. To the traditional rules he added those of the "a la rabiosa" technique.
One hundred and fourteen entries, with the detailed transcription of the individual “decisions” and the resolution of chess problems, complete the contents of the book.
