I keep seeing a really big improvement with chessmaster 10k w/o log file. A
modest improvement for chessmaster 9k w/o log file. I am using 4min+2sec time
control. With longer time control, less improvement is likely.

My testing is not statistically adequate to make a valid conclusion. So let's
just say I'm making a suggestion to cm9k and cm10k users to try it without the
log file. To remove the log file when using fritz8 gui, blank out the log file
in "inbetween.ini".
