  Jim Bartle: I just noticed that games are listed as round 79, 87, 123. Wonder what happened in the 100 games not listed here...
Dec-11-07  parisattack: <Themofro: > Thanks for the Bird pointers! Bird's was the first opening I played and I had wonderful luck with it; thus a fondness 40 years later for it. In the grand scheme of things I think the first move is a little early for the committal f4 - but if you don't forget development and watch the square weaknesses its as good as anything else under 2400 elo.

I also definately agree with holding back d4 if you're going for a Stonewall. The extra move over the Black Stonewall has little or no initiative value but offers developmental flexibility.

Jan-08-08  Kombi: Amazing stuff! I was actually happy to see something like this.... maybe because at some point I became one of those non-believers. Now I see some hope and understand better what to do and how to play against computers and computer-like young players. ;) Thanks for posting those games!
Jan-08-08  MichAdams: <I thought love was only true in fairy tale. Meant for someone else but not for me.
Love was out to get me
Thats the way it seemed.
Disappointment haunted all my dreams.

Then I saw her face, now Im a believer
Not a trace of doubt in my mind.
I'm in love, I'm a believer!
I couldnt leave her if I tried.>

Jan-17-08  Knight13: <Jim Bartle: I just noticed that games are listed as round 79, 87, 123. Wonder what happened in the 100 games not listed here...> He played over 200 games, all win against Fritz (with one draw NO LOSSES) and I don't feel like submitting that many games so I picked the most interesting ones.

  Jim Bartle: Very impressive, then.
Mar-06-08  Lorenzon: WOW, what an impressive score against Fritz.
I wonder if he could do it again nowadays...
Mar-07-08  Knight13: <He played over 200 games, all win against Fritz (with one draw NO LOSSES) and I don't feel like submitting that many games so I picked the most interesting ones.> Sorry I mean over 100 games, with 128 games total in his book.
Mar-21-08  awalters869: I am sure this individual spent alot of time playing behind-the-scenes practice games and looking for the flaw/weakness in the code. Most computer programs have difficulty playing closed positions --- take away their main strength (tactical perfection) and they begin to show some cracks as far as long term positional play --- which is usually what closed positions create ...though Pecci did have some great tactical shots !?
Mar-21-08  awalters869: this was OTB play ...not correspondence right? with normal time controls?

  whiteshark: He wrote the book <Chess: A Psychiatrist Matches Wits with Fritz> afterwards.

It's a "compilation of over 125 games systematically illustrates a strategy that succeeds in beating today's best computer chess programs. With a detailed description of the steps that lay the groundwork for victory, this manual includes easy-to-follow diagrammed chessboards to illustrate each move. It also contains a description of the conventional principles of chess as well as the strategic differences of computer chess."

Tks to for the synopsis. :D

Aug-05-08  awalters869: there are two miniature wins for pecci ...with the black pieces!! Wow!
Apr-23-09  Raisin Death Ray: Do I amuse you?
May-15-09  SirChrislov: This Guy has a book called "a psychiatrist matches wits with fritz". he shows you how to beat computers using his "barrage position" example: 1.d4 Nf6 2.e3 d5 3.Bd3 e6 4.f4! followed by Nf3,Nbd2,Qe2 and a K-side p storm. you should get the book if you're crazy about beating your program. I defeated an old version of Chessmaster with it. it's nice to see the program play on in a lost position until mate. because as you know, comps never resign.
Jun-26-09  Knight13: <because as you know, comps never resign.>



Aug-04-09  Dredge Rivers: Where's his brother Joe?
Aug-04-09  MaxxLange: I looked at his book in Borders a few years ago, it was very interesting. I would have bought it if it had been less expensive.

I think the most recent games were against the Fritz 6 or maybe Fritz 7 era of chess programs. Basically he was working a really slow Stonewall attack, and perfecting how to work it. Kramnik beat Junior horribly in the same way about 2000.

I'd love to see an update of how his system does against today's engines. Not so good, I expect. One could argue that Nakamura's Hippopatamus experiments against Rybka on ICC continue Pesci's work.

Dec-11-09  M.D. Wilson: <Dredge Rivers: Where's his brother Joe?> Haha.

So this guy is a psychiatrist? Anyone know anything more about him?

Mar-25-10  birthtimes: "A retired pyschiatrist, Dr. Ernest Pecci has succeeded in finding the limitations inherent in the belief systems utilized by chess programmers in creating today's best computer chess playing machines...For 40 years he has studied both Western and Eastern traditions in the understanding of consciousness, intuition, and the untapped potential of the human mind"...from "Chess: A Psychiatrist Matches Wits With Fritz", foreward by Gary Kasparov.

Dr. Pecci has also written such well-acclaimed books as "The Violence Potential", "Guidance From Within", and "Rise Above It."

  whiteshark: <rapidcitychess> No, a few months back. I remenbered it when I saw your post here. :)
Aug-12-13  GumboGambit: According to Rybka, Peccis constant need to beat this computer at chess is undoutedly rooted in a series of insecurities caused by overexposure to Fritz The Cat cartoons. His uncommon opening choices are clearly a desperate cry for attention. To remedy this disorder, Rybka prescribes Percocet and Ritalin to offset this fixation. Also, weekly therapy sessions @$150 per.
