Some (but slow) progress..

Well, my windoze64 expired, so i did an upgrade with a Vista OEM;
for the rest, updated my positional database again, with lots
of games analyzed (endnode values) with Rybka, now
more than 15 million positions. Full minimax again, and started some
finetuning/checks of the 'best' lines; then had to struggle quite a bit
with the Najdorf variation of the Sicilian.

First it appears that the variation with Bg5 was the best for white,
and i had to look a bit further to the complex poisoned pawn
variation. But in the end i went back to a more common variation,
namely with Be3, the English attack. With a plan of long castling
(after Qd2), it looks promising for white, but i have to play
much more games before i have a conclusive result.

Any other results ? Well not many, i'm starting to update my
main lines of the closed Ruy Lopez (in which i still managed
to keep a slight advantage , ie += for white), and then
have to plug them into my Arena book. Have played
some comp tournaments with the new Arena beta4,
which again looks much better, but unfortunately
it doesnt seem to play on the internet yet.

And still have to update my 'superchess' website,
coming year trying to switch it to my domain name
bookbuilder.nl, and maybe add some more fancy
stuff about opening theory and/or computer chess.

Last rating record ? Well with quite a big selfmade book now
with Arena (50M), almost the size of the 'Schnapps' book,
and the latest Rybka (using the lkmp64 version), i achieved
a new bullet record on ICC in March, namely 2994.
Latest records were from November last year (standard),
but i'll try to improve on that again coming months..
:)

Until later,
