There are three stories in the contest between the IBM-backed chess program and the then World Champion, Gary Kasparov:
.. the human story, both of the programmers and Kasparov
.. the chess story, what moves were made in the matches
.. the program story, why the computer made the moves it did.
This book does one and a half. The human story is overwhelmingly from the programmers point of view and the chess aspect is good enough for the non-chess expert (once you avoid the errors another reviewer has pointed out), but there is almost nothing on the program itself. If you're interested in creating computer programs, rather than reading about the struggle to create them, this is not the book for you.
In that sense, it's a bit like classic book, The Soul of The Machine, which told the story of the creation of a new minicomputer in a way that minimised the discussion of the actual hardware. In both cases, the team had problems and solved them, but you'd never know how from reading the books, only that it involved lots of effort.
This book is a good account on this famous match. Many books have been written on this match, from the chess players point of view and also the chess programmer. This book concentrates on the latter, but also gives some great background into the match as it happened, something that is lacking in a lot of books on tournament matches. I found it interesting to compare Deep Blues moves with todays chess programs, and also to read about Kasparov's reactions during and after the matches, especially in light of his recent match against Deep Junior ... It is a good read for both chess enthusiasts and chess programmers. There are 16 chapters plus 13 appendices. The first 6 chapters concentrate on background information on computer chess,deep blue development and its earlier matches. The remaining chapters cover the 1997 match itself, the lead up, 3 chapters dedicated to 3 games that were won, and 1 chapter to the 3 games drawn. The appendices are excellent with moves/times/diagrams on all matches played by deep blue and its predecessors.There is even the full log printout of deep blues thinking during one match. (these can also be obtained from ibms research web site ..) I dropped a star because there are a lot of typos/mistakes in the text, especially with games moves ( Kasparov first move in one game is Knight to g3???) .. it looks like it was not edited properly by someone who knows chess. The appendices are correct re: game moves but have some errors in who resigned after the final diagrams ...
