No one can explain to me that 1.e4 in round 10 with the same book and similar
bookline would have won there.

This where Noomen when he sees a line that can win potentially against a
program, he is taking 10 minutes effort to modify the books short before the
game, also against for example DIEP.

DIEP-Sjeng

Noomen sees this line against diep and loudly says he finds it a great line for
black, because white has played a nonsense move Qa4 (according to Noomen).

He knows that i haven't modified book of course. Then some hours later there is
the game DIEP-Rebel.

Before the game, noomen goes find the book that he used for Sjeng and does all
kind of stuff that i cannot see of course but it has to do with book issues.

Only when games start then he copies the game, knowing i have not changed the
book:

61.Kc1 Nb4 62.Rg1+ Kf6 63.Rgg8 Nxa2+ 64.Kd1 Nc3+ 65.Ke1 a2 1/2-1/2

So he plays same opening again, of course which is legal though i didn't find it
very sportive because he knew i had not modified book and he did effort short
before game to select the book he had delivered to Sjeng. I found that out of
course during the game.

Rebel plays other move, diep reacts wrong and gets lost endgame. Then because of
bugs in Rebel it still blows it.

So Noomen copies game against diep when he guesses it can be advantage for
Rebel.

When however Sjeng can profit in the same way it gets not done.

Why?
