Didzis does not only let CM idle. To have it really idle, you have to open a
dialog box. When you do so, Tiger is not slowed down significantly.
Try it, and you'll see that you'll get almost no slowdown.
>Aside from this, Ed's findings about PB on/off seem quite conclusive to me.
Ed has just demonstrated that PB ON adds a significant amount of strength to a
program. He has not given comparative results about 2 program playing each with
PB OFF.
My permanent brain management follows another philosophy and I have no problem
with testing Tiger with PB OFF.
I don't want to find any excuse if CM7000 beats Tiger.
However I don't understand exactly why the discussions are taking place NOW. The
current score is 4.5-2.5. Only 7 games have been played.
Just turn only 1 loss into a win (you know how easily a game can turn from win
to loss and vice versa in computer chess), and you get an even result.
Let's wait for a significant amount of games and we will see...
