Practical relevance/opening repertoire

Now after the previous ideas and perfect opening lines, whereby black can maintain a draw, one can (and indeed should) ask what's the practical relevance in chess..

Well first of all, by using such almost perfect opening lines, an opening book for a chess program becomes much better of course. Much better ? Well, at least slightly better. For example i've tested my Arena book against the main book by H.Schapp, and achieved improvements of about 60 Elo points. Not really very much, and indeed, the engine/tactics still are much more important.

So what's the relevance of such opening theory for human players ? Well, having thought about this a bit more, i suspect that the approach of finding 'best' opening
moves is not really suitable for human players, having not such perfect memory as computers of course.

Yet another approach can be worthwile, namely choosing opening lines which restrict the number of playable options
for the opponent. Does this mean choosing the sharpes…

Criticism, theory, etc.

In a recent discussion on Usenet, rec.games.chess.analysis
my 'conjecture' (hypothesis) that chess fundamentally is
a draw, was critized by some people. Trying to give
some evidence, i showed some standard comp-comp
games, eg. with Rl Zaitsev, and Queens Indian,
where black clearly could maintain a draw.
But people may still question such 'evidence'
of course, as there are many many other lines.

Yet, with perfect play for both sides, assuming
white tries to maintain some initial positional
advantage, i found that often Ruy Lopez, and
against d4 black Nimzo Indian or Queens Indian
are the result of such 'perfect'games.

Then again, one may wonder whats the relevance
of mentioning the RL Zaitsev variation as the
main drawing line for black after 1.e4 , as
white for example doesnt have to play 9.h3
in the Ruy Lopez. Well this doesnt matter,
otherwise i wouldnt have mentioned such
lines. Of course i also have analyzed other
possibilities, eg. with 9 d4, the Boguljubow
variation, …
