This board is interesting. Things of interest happens here, and real
computer chess stuffs are discussed.

The only bad thing is that people always feel the need to say something,
even if they have nothing to say. For example: I have nothing special to
say about journalism, but with this sentence I just managed to say it!
And the problem is that this thread could quickly become: "what to do if
you have nothing special to say today about journalism". This thread
could well continue until year 2000, and become 90% of the postings on
CCC.

So I just go back to computer chess and, yes, I saw Junior in Paris. One
day, it was doing a kind of self-play. I suppose Amir was testing the K6
computer. The rate of play was roughly 1s/move. I was very surprised to
see very long lines on the screen and stood there for a while. In only
1s Junior was able to compute 10 or 12 plies lines. And the last moves
usually were not captures.

I don't like to bring unverified news, so maybe Amir could confirm what
I say. I often read postings from him on CCC, so he's likely to read
this tomorrow!

Anyway, I was impressed by Junior's depth. As a chess programmer I would
like to achieve something like that. My program, Chess Tiger, is fast
and usually reaches ply 8-9 in blitz on a P200. But Junior's algorithm
is smarter. The only program I know with a similar behaviour is
Genius...
