Hi,

I hope sometimes next year.
Depending of if there will be a 2005 WCCC or not it could be next summer.

A deeper book is better, but the moves should be checked.

The book increase the program strenght if the lines are good and the program
gets good positions. Some times the score given by the program is not correct
and after some moves the evaluation improves move after move. In most positions
however it is better to have a positive score. It depends on the
positions/lines.

If some lines are weak and the opponents know that you will play them than the
risk to lose some games is quite high. This is the same with human players too
even if they may "feel" the danger while the computer will play what has been
put in the book.

We lost the first 2 games due to this problem. Also we did not know what our
opponent would play while they knew it with a good percentage.

I knew we were not ready for the match and we underestimated Hydra strenght too
also considering the very powerful hardware.

Next time it will be different as we will prepare carefully.

I hope there will be Shredder 9 for sales before the end of the year, but we
need to have a quite stronger version to sell, so we are working on it.
When it will be ready it will be announced.
