Jul-16-10  TheFocus: I once dreamed that I would one day become a Grandmaster.

But that dream did not come true, so I dreamed of becoming an International master.

Didn't happen, so I dreamed of just becoming a Master.

Ditto, so I tried to become an Expert.

Something was lacking, so I dreamed of being just a Class I.

Guess what? Nada.

So on and on, until I dreamed of just getting a Class WXYZ rating.

Then I woke up and found out that I had wet the bed.

Jul-17-10  The Famous Chess Cat: <SetNoEscapeOn: Taken together, tabbed browsing and Wikipedia are both the joy and the bane of all curious minds "suffering" from ADD.>

I wholeheartly agree!

Jul-31-10  just a kid: Deep thought...something that is impossible for me to do :)
Feb-14-11  seeminor:

Excellent doco

Feb-14-11  Whitehat1963: It takes a big man to lose a game gracefully. It takes a bigger man to laugh at the loser.
Jul-01-11  SetNoEscapeOn: "Don't put all your eggs in one basket."

But if one has only one basket...? How many baskets can one carry, anyway?

Dec-22-11  whiteshark: What we do in life echos into enternity.
May-15-12  whiteshark: What is spare time when time is relative, Albert Einstein?
Jun-09-12  PinnedPiece: One ponders why the Deep Thought page at CHessgames has only four pages of thoughts.

What makes a thought deep? Is a deep thing desired? A deep valley makes travel difficult, and can separate things...

--- ---- ---- ---

What makes a thought deep? The deepest parts of the ocean are lifeless, oxygen-deprived, canyons of eternal darkness.

--- ---- ---- ----

What makes a thought deep? If you probe into the deepest, furthest recesses of man's physical brain, you enter his reptilian zone.

--- ----- ---- -----

What makes a thought deep? The most common phrase in English for being in a deep place is actually rather unpleasant and foul-smelling: I'm in deep d_ _ d_ _ now!

--- ---- ---- -----

What makes a thought deep? When we view deep space, we are looking at energy that has taken years or thousands of years to reach us. Does a deep thought take years to appear?

--- ----- ---- ----- --- --

What makes a thought deep for a computer? It has piled lots of calls on a recursion stack, and as often as not, if you are not careful, you crash.

---- ----- ----- --- ---- ---

Perhaps deep thinking for me just means pondering questions I can't answer?


Oct-02-12  SetNoEscapeOn: The regular members of this site are the biggest fans of elite chess in the entire world.
Oct-20-12  whiteshark: Time is a great teacher, but unfortunately it kills all its pupils...
Oct-20-12  whiteshark: The road to success is always under construction.
Nov-05-12  whiteshark: If Atheists are so bad then how come AtheistZilla never attacked Tokyo and Godzilla did?
Nov-05-12  RookFile: Toykyo needs to have their buildings knocked down every 5 years. It's good for their economy, they get to rebuild them for next time.
Nov-05-12  rapidcitychess: So if we are all nonexistent, and imagining everything, then how did you just tell my that I am imagining everything? Do I know I am imagining things, but I don't actually know?
Jul-02-13  whiteshark: And now something completely off-topic:

"<Deep Thought> was a computer chess machine built at Carnegie-Mellon University in the 1980's. It was a predecessor to Deep Blue, the chess machine that defeated Garry Kasparov in a match. Neither machine exists at this time.

<Andreas Nowatzyk> was one of the contributors to the Deep Thought project while he was in grad school. A few years ago when he and I [<Tim Mann>] were both working for Compaq's research labs in Palo Alto, Andreas sent me a copy of Deep Thought's evaluation function tuning program and asked me to put it on the Web for him, since he no longer has an interest in computer chess.

If you are interested in this material, you can download it here. Please don't ask me questions about it; I had nothing to do with developing it, and I don't have any information beyond what is on this page.

Explanation written by Andreas Nowatzyk in January 2000.

God only knows.

Oct-12-15  Esauwept: I can't find the supposedly well-annotated games between Kasparov and Deep Blue computer. Does anyone know what game collection they are in? Many thanks
Oct-12-15  Howard: There's always the Informant. Otherwise, there's good commentary right here on this website, though (admittedly) you have to wade through a lot of spam-like comments.
Oct-12-15  King Radio: The Pandolfini book on the match is pretty good, and it's pretty cheap.
Nov-04-17  TheTamale: I used to think Deep Thought was an incredible machine. Then I noticed something missing... an utter paucity of 10-move demolitions of NN. Deep Thought might be a strong player, but it's no Greco.

  perfidious: In the US Open held at Boston 1988, I faced the silicon wretch and was put out at losing to it--in the very next round came the demolition job Deep Thought vs Igor Ivanov, 1988.
