Subject: new style for ChessSystemTal2.03 on faster hardware

hi,

i have made some observations in the last time while watching CSTal2.03
playing.

1.I think i have found out why the program plays weaker with black
(bug in the variables. Line-activity goes into minus. IMO a variable
out of range going into minus).
2.Also i think i found out that there is a bug in the null-move search
(causing wrong pruning).

Overall i have created a style.

it only works 40/120 on fast hardware (>=1200 Mhz Athlon).

Thank you.

You can get the small style via email from me.
if somebody has a web site, feel free to set it up. Its public-domain.
Just copy the style into the datafile-directory of cstal2.03.
this automatically loads it when starting. you will find out that null-moves
is switched off. but playing strength (especially with black) has increased.
