Whey should they print 11 ply if they search 15 ply?
11 ply fullwidth with all those extensions is of course horrible.

We're not talking about me only, we're talking about all GM's here.

Read Seirawan analyzes ICCA june 97.

Yes, i'm not talking about winning games. Just 1 horrible move can
make you lose.

KK kup was fake. Diep got black in the only 2 important games.
Just 2 games.

And Diep got outbooked by both programs.
Game against Rebel it was directly lost. Diep's horrible in French.
Just look at ICC the % of wins of Diep in French.

This looks like this test conducted by Fernando Villegas.
My program was suddenly good because it managed to win
quicker against a small computer.

2500 SSDF says nothing.

Don't you get it, all programs sent to Sweden have played say 10000
auto232 games or something.

Sweden became one big book tuning event.

In the future this might change if books get more variaty.

Until then this Sweden list is laughable.

How can a program like Fritz5 which loses normally to all those programs
can get on top?

How can Rebel9 get stronger than 8, considering that the only
4 things changed are interface,few extensions to solve some tricks,
BOOKLEARNING, and with capital letters BOOK.

The program didn't play better, yet it got a higher elorating because it
scored better in matches.

That kind of comparision is wrong. It won't play better against humans
than Rebel8 nor will it play better in tournaments.

A simple 1.d4,d5 2.Bf4 was enough for Diep in aufsess tournament
to beat it.

No doubt that when i send my program to Sweden that  i will
have played some hundreds ot auto232 games too (i'm only
having a Pentium pro 200 and a laptop 133, so i can't produce
thousands of games like the pro's).

Your computerchess insight is laughable.

A program just playing 6 games in its life you call God.

Where i need to get a rating in Sweden based on cooked lines
after hundreds of games, or thousands of auto232 games, before
you believe me?
