Number One (on ICC)

(mainly) as result of the strong Houdini 1.5 engine(*), but
also due to the recent improvements in my Chess Partner book,
got a new 'standard' rating record of about 3050 on the
Internet Chess Club (ICC) with my 'bookbuilder' account,
on 28 December 2010, and nr 1 rating
for standard (rapid and slower_ play) !

On a 'simple' Quad comp, while there are some 6 core
comps around (with often an intel icore extreme), so
using a good book, does it matter ?

Yes, indeed it matters, especially at higher levels
of play (i.e. slower time controls, like in standard),
this now simply is proven in actual play,
and it makes sense, a chain is as weak as its weakest
part, and for a chess program this means everything has
to be without weaknesses, opening book, middlegame
(engine) practical endgame (engine) and theoretical
endgame (tablebases); have a lousy book, and against
a similar or even slightly weaker engine the
game can be lost, it makes a difference +/- 100
Elo or so, is my ex…

intermediate repertoire

Having found some better repertoire for advanced players,
and simplified the 1.e4 repertoire for beginners (exchange
RL instead of closed RL), a repertoire for intermediate/
average players was still lacking.

So, using some more recent analysis with Rybka4, i added
such a repertoire in my book 'better chess opening play',
and now advise the Petrov (e5 e5 Nf3 Nf6!) against e4,
instead of the Ruy Lopez (RL). Whereas i found it to be
more solid, it also avoids variations as Scotch, Giuoco
Piano, and many related gambits.

For further info see the book, a new version now has been
uploaded, and is available for registered users of Bookbuilder.

NB End of year 2010 special offer:
50 % price reduction !

While the book is not finished yet, i'm sure the latest
version can help you ie most chess players except super GM's
a lot in your chess play, and i also am getting to get
some positive feedback (eg from one user in the USA:
"excellent E-book") .

advanced repertoire with 1.d4

having done some more research with Rybka4, which in many cases
gives a better evaluation of some positions than eg. Rybka3,
another repertoire, which i use in my computerbook is emerging,
namely with 1.d4 .
Against e4, having done considerable analysis on many lines
and playing some testgames both on ICC and,
the Sicilian 1..c5!, in particular Najdorf, (with d6 and a6)
looks quite a strong defence, currently even the strongest.
In fact these developments are not surprising, as many top
players also have switched their repertoire from e4 to d4, eg
world champion Anand. Although its often said that this is because
of the Petrov or the Marshall gambit defence in the Ruy Lopez,
for me the reason is the Najdorf, which in fact is played quite
often on against e4. Highly accurate play is
required in this sharp, double-edged defence, so for average
players - and certainly beginners- i still advocate 1.e4
as most suitable repertoire.
By starting with 1.e4, you learn vari…

Improvements in the Ruy Lopez

found the Russian Firebird 64mp engine, of which it is said that it
has been made with reversed engineering of Rybka. Well anyway
tried some new analysis. While less solid than Rybka, Fire(bird)
very fast sometimes finds interesting lines, and i seemed
to be able to maintain some slight advantage against both
the Zaitsev (9.. Bb7) and the Chigorin defences in the Ruy Lopez.

For example, whereas i previously thought black is ok in the
main line Zaitsev (9..Bb7 10.d4 Te8 11.Nbd2 Bf8 12.a4 h6 etc.),
with new analysis a rather obscure line, namely with 12.Ng5
seems to be able to achieve a white advantage.
After 12.Ng5 black plays 12.. Re7 to cover f7, and now
the (rare) move is 13.Ndf3! In Guez(2177)-Colin(2402),2005 black
played exd4?! (.. h6 also has been played, but 12.. Qe8N is
probably best), white played 14.cxd4 (Nxf7 would have been
better), and after 14. .. Qe8?! (Na5 would have been better)
we get the following position:

Now white could have got the advantage with 15.e5!N but
being a lo…
