A psychiatrist matches wits with Fritz

5/18/2002 – When's the last time a "how to" book really solved your problems when it came to love, children or money? Not to mention how to get the better of your PC chess opponent. Psychiatrist Ernest F. Pecci has written a book that makes defeating Fritz seem effortless. Does the book deliver? James DuBois uncovers the truth.

CHESS: A PSYCHIATRIST MATCHES WITS WITH FRITZ

A review by JAMES DuBOIS

Dr. Ernest F. Pecci, M.D. has written a physically formidable how to book on the subject of defeating our beloved (most of the time) Fritz. As expect from a lifelong psychiatrist this nicely bound book is quite academic in nature with its gold lettered spine and burgundy covers. The dust jacket is littered with praise and hyperbole from both ends of the ELO scale. A certain Mr. Wilmont McCutchen is quoted as saying that Dr. Pecci's Bird's Strategy raised his rating by 200 points, while Garry Kasparov proclaims the book as having "...a far reaching influence on shaping new ways to approach the game of chess ...." The four hundred plus pages are overflowing with strategy and diagrams with some interesting personal insights by the author.

This reviewer must take at face value that every word in the foreword was actually written by Garry Kasparov. He briefly mentions Deep Blue (of course), Advanced Chess and Rapid Chess. There is a definite sense that he truly does believe in Pecci's system and makes an almost spiritual connection with the "creative intuition" aspect in the battle of man versus machine.

We learn from the author's preface that he began playing chess again after Kasparov-Deep Blue, 1996 even though he hadn't played since the early 1980's. He started with Chessmaster 3000 and progressed to Fritz 6. He writes that this program is considered to be nearly unbeatable and was frustrated by it. With some "slight adjustments" he was able to defeat it from a number of openings in less than 40 moves. "I had developed strategies and tactics that were considerably different from modern chess theory to combat ideas that had strongly influenced the chess database [sic] programmers." A healthy ego at work. At this point I was extremely anxious to test his theories, but I also could not help from reading on when encountering statements such as, "...White should be able to win or draw every time regardless of what black does." Conversely it would have been as challenging for Pecci to finish that sentence with, "...regardless of who or what Black is!" He does confess, "In enjoying a game for pleasure, I might, sometimes take one or two 'blunder' moves back...." "I would gladly offer the computer the same courtesy, but why should a computer need it? Computers don't make mistakes."

We are introduced to Edward Sheppie, a well rounded chess player who discusses his relationship with Dr. Pecci and how his chess was changed forever. Sheppie writes, "There is a certain sense of exhilaration associated with beating Fritz 6 in a blitz game without having to take any moves back." He tells that Fritz had a more than adequate time allotment for the games played in the book to allow a full search to arrive at the best move. The scope of this work is seemingly as endless as the game itself. I must reiterate, that this is a physically formidable book. That doesn't translate to dull by any means, especially for devoted Fritz users. More short chapters follow with the emphasis on rethinking, that our "surface minds" are no match against a computer. Agreed. Pecci acknowledges several times that chess playing programs do come in an assortment of strengths. "...the highest rated programs... put you on the defensive very quickly." I believe for the most part he does know the subject matter well enough to author a book of this stature and that he has a deep love for chess, computers and the human mind. Our kind of guy. "...there is enjoyment in often disagreeing with the evaluation it (Fritz) gives your move selection." Sure, if you win.

I disliked the author's parallel of chess as a military game. It works for the purpose of the book in the middle chapters as Pecci outlines "establishing an attack trajectory to the castled King", but I think we (certainly ChessBase users) are far more sophisticated to perpetuate this metaphor. This leads to the main concepts of the "Barrage" position. It is essential to obtain an inverted triangle of three pawns. White wants pawns on d4, e3 and f4. Ideal is the Bird opening. Then push the Kingside pawns to the fifth rank as quickly as possible while contemplating 0-0-0 or just playing the King up one square. "A pawn chain obstructs the Black pieces from engaging in the defense of their King." It's not quite that easy and the author warns that the moves must be precise.

After demolishing the bulk of the Chessmaster series, Fritz 5 is "...approached with some trepidation." Game one was drawn. The author's resolve was strengthened to refine his system until he could routinely defeat Fritz in an average of 30 moves from a variety of openings. His second game actually brought Fritz to its digital knees. The bulk of the book (300+ pages) consists of the author illustrating how his barrage position system wins with a variety of openings. He includes many standard openings with emphasis on Bird's Opening (because of Fritz's consistent response) for the human, of course not omitting From's gambit and with a lengthy chapter, "Fritz plays White." Fritz wouldn't be the same without his personality. The author found the licking sound of Fritz's chops "annoying" as he goes down two pawns in a game to ultimately come out the victor in 36 moves. The book closes not with glorious praise or condescending conclusions, but with one last game against Fritz 6 as the author woke from sleep with some self doubt, "...despite hundreds of victories...." "The result was one of my most satisfying games." This with the program set at its highest level.

With all this said, the acid test for the book comes down to one single question. Does the method outlined by Dr. Pecci work for players other than him? The only acceptable way to give credibility to his system is if any player of average playing strength (or stronger) can assimilate the theories outlined well enough to win at regular intervals.

I began with some play on the Internet Chess Club site. My rating for blitz on this server generally stays around the 1700 mark. I sought out my online computer nemesis JSBach. I enjoy playing this program because it does offer chances instead of the elite (some rated 3000+) and snobbish programs that occupy the ceiling of the seek graph. I confess that I did loose a fair amount of games because of the learning curve involved in gaining a barrage position. Most of those games were closer than usual, but the clock was an adversary since I needed the few extra ticks to play more precise. This game was my first win. It is also the first win in my life with Bird's Opening.

However, I do see some logic here. 8.Nbd2 h5 9.Ne5 Double d pawns are okay according to Doctor P.  9...0–0–0 In the classic Pecci dictum I strive for 0–0–0 while my opponent goes 0–0.  10.0–0 Still the opposite wing castling principle is just as effective and follows the plan. 10...Rg8 11.b4 Rd6 12.b5 Nd7 I think the program just didn't comprehend what was going on. Black is now on the defensive no matter which alternate moves could of been played. At this point it's pretty much over and I'm wondering how I'll fair against Fritz. Surely it won't have a brain cramp like this.13.bxc6 bxc6 14.Qa6+ Kd8 15.Qxa7 Nb6 16.Qb8+ Nc8 17.c4 Qf5 18.c5 Rf6 19.Ndf3 g6 20.Ng5 Bh6 21.Bd2 Rf8 22.Ba5 Ke8 23.Qxc7 Nb6 24.Bxb6 Rd6 25.Qb8+ Qc8 26.Qxc8+ Rd8 27.Qxd8# Thank you Dr. Pecci for the virtual rating points! 1–0.

I can quite honestly say that I gave the Pecci system a more than fair examination against Fritz 7 at a variety of time controls ranging from blitz (game in 5 minutes) to games of 40 moves in two hours. Running on a 1 GHz Pentium III machine with 256 megabytes of RAM and assimilating a new chess paradigm made for excruciating play on my part. I'm sure that I exhausted Fritz's insult repertoire.

The book included over 4,000 diagrams illustrating how Fritz's king is to be naked at the conclusion of the game. I find it extremely difficult to digest that it is as simple as stated to accomplish said task. Returning to Mr. Wilmot McCutchen (quoted earlier) I'd be very interested in seeing how he handles Fritz 7 on compatible hardware since his peak rating was almost identical to mine, thus putting us both in the majority of the rating pool. This book seems to be geared for the strong club player up to Expert. I believe that I understood the concepts, but was it my own weaknesses as a player and/or my psychological composition that lead to my failure with his approach? If so, then the system itself fails since it is not universally adaptable. The book is definitely intriguing, but perhaps more so would be a contest similar to the recently completed Ilya Smirin match, replacing the GM with the doctor and have him square off against the ChessBase stable of thoroughbred programs under the same playing conditions.

There is a conviction to the book; otherwise I'm sure Pecci would have never written it. It is thought provoking, well produced and is of some worth to chess computer aficionados (primarily Fritz users) if only as a curiosity. I don't see it as a panacea for the man versus machine battle or as the "how to" book on defeating Fritz. Perhaps solving the problems associated with love, children and money will after all prove to be easier subject matters.

REVIEWER'S ADDENDUM

Just as the author questioned himself the night before sending the book to the printer, so did I question myself as to whether I played to my full potential regarding Dr. Pecci's system. Without comments or annotation, here is my last game before pointing my cursor to send.
