Review by Tim Bourke: The first half is largely an exposition of Culbertson, with some ideas from Acol, in the first edition. In the second the bidding was based on Acol, with honour tricks as the primarly valuation method, and with some add-ons from other systems popular at the time. The second part of the book has over 100 pages on the play of the hand. It is only the latter that remains of any real interest today.
