Chessmaster 9000 oddity noted in "old" forum

[rhoadesb]

For anyone who remembers and is interested, I ran a second set of 100
games.

Basically, the personalities were Chessmaster 9000 with the following changes
in both runs:
pondering was off
randomization was set to 20
the opening book used by both runs had only one line, which was: 1. d4 d5 2.
c4 dxc4
after that, both white and black were out of book.

The only change I made for the second set of 100 games was that I also cloned
the ONE opening book that the two were using. So that while each had the same
knowledge of 4 plies as indicated above, Physically there were two books.

This may have had an influence since the second run showed 33 wins for
personality 1 and 29 wins for personality 2. This is much closer to what I
would have expected.

At what time controls did you play 'em out?
I think it's fairly fast 2...dxc4 they are both out of book. I think that being out of book is a bigger problem for then personaliry in blitz games than in standard. Perhaps the results would be different with another time control?

A grandmaster needs to retain thousands of games in his head, for games are to him what the words of their mother tongue are to ordinary people, or notes or scores to musicians. – Garry Kasparov

All games in both runs were at Fischer 15-15 time controls.
