As result of many testgames on playchess.com
and including the games with Rybka analysis
in my large database, some variations in my
book have been updated. For example in the
Queens Indian, after d4 Nf6 c4 e6 Nf3 b6!
g3! i've replaced the bookmove Bb7 with
the more modern Ba6.
Also, against the Sicilian Najdorf, my
preferred bookmove is now Bc4!, the Fischer
attack. While not always getting an advantage
for white, at least the results are better
than with the English attack, Be3, which
still is played often, but against which
black can hold equality with carefult defence.
For the rest many update were made to my book
'Better chess opening play', of which you can
see some selected pages at:
More in general, when comparing the results
achieved when looking for the 'best' bookmoves
or opening variations -as result of Rybka3 analysis-
seem to become in line with mainstream theory,
as published in many specialized opening books,
which in principle is an encouraging result;
and proves that the evaluations made with
the Rybka 3 engine indeed make sense.
When appropriate, and possible, with deeper
analysis ofcourse some improved lines can
be found, and in such a way computer chess
is getting ahead of GM games, even games
played by the top-GM's..
