Black is ok, chess is a draw with perfect play..

With some more Rybka analysis, i'm convinced that
chess is a draw, with perfect play for black.
After e4 e5!, and with the Ruy Lopez it seems not
possible anymore to obtain a structural advantage
for white. Neither with the Bobuljubow Ruy Lopez
variation (8.d4) nor with the Closed RL with 9.h3,
as not only the Zaitsev (10..Bb7) but maybe also
the Breyer (10..Nb8) can maintain equality
for black, i.e. equally valued positions.

Of course careful play for black is needed,
to anticipate any winning plans for white,
but i've analyzed these lines deep enough i think
that a draw seems 99.999 % likely with perfect
play for black.

If one would talk about 'solving' chess, ie.
trying to find a forced win for white against any
defence for black (like eg. in four-in-a-row) then
proving chess would be a draw, also would be a
'solution' of chess. So, i now can say that
chess has been 'solved', its a draw.. :)

'Proof':
*if* there would be a forced win for white…

Opening theory and the art of bookmaking

Having looked more in detail into 'my' repertoire,
i.e. the opening book(s) i made for Arena it
appears that gradually i'm getting into new theory.

This is because conventional theory, and also
most 'conventional' opening books are based on (top)
GM games. But the deeper you get into a line, the
fewer games there are, after which the theory gets
very dependent on just one or a few games.

The statistics then get unreliable, and it the of
course is interesting to analyze some of the most important/frequent positions with the top engine
Rybka (in the past most computer chess programs,
i.e. 'engines' were positionally not good enough
to make good moves/ evaluations, but with the latest
Rybka 2.3.2 i believe it can be used to make
professional/GM quality evaluations); this sometimes
leads to interesting results, eg. more solid defences
for black in lines such as the closed Ruy Lopez,
Zaitsev or Breyer variations (doing a full minimax
with the old Boo…

A new start

First of all best wishes to all for the new year 2008.

For this year, i've got some plans to renew my chess repertoire.
After comprehensive analysis and computer games with
the top engine Rybka, it appears that 1 e4 still is
slightly better than d4. Games by Rybka with the Noomen book,
and also human games by Anand seem to confirm this idea.

In my own computer-repertoire, there will be some changes,
and i will write them down in the e-book 'better chess opening play',
so i'm planning a new version, probably ready in a few months.
Writing down the new variations will take less time,
probably only a few weeks.

Some noticeable changes: the Caro Kann defense has become
stronger for black, and the 'best' line for white now isnt
the advance line anymore, but more in line with the
classical lines, with a few improvements of course.
Against Sicilian, both in the Kalashnikov/Pelikan/Sveshnikov
as well as the Najdorf (English attack with Be3!) it appears white
can maintain a positional a…
