small update (for the chess book)

a few corrections;

Having looked at some transpositions in some more detail, i
will re-arrange some chapters in mybook in the positional
repertoire; after 1.d4 Nf6 2.c4 c6!? 3. Bf4,  Black may still
have some problems after all, although i had analyzed such stuff.
So after 1.d4 Black can probably better play d5! going for the Slav
(2. c4 c6! but then Black can also throw in a dubious  Albin gambit
2...e5 no big deal. And 2.Nf3 still is possible, but then after 2...Nf6
3.c4 c6! Black is going for the solid Slav defense again

Secondly there's another possible improvement, in the Moscow
line, After Bxf6 Qxf6  instead of the neutral 8.e3 because
of the strong defense systems with ...g6!, White might  better
go for the Hastings variation with 7,Qb3!?, although
also then Black can equalize, for example:

1. d4 d5  2. Nf3   Nf6  3. c4  c6  4. Nc3 e6  5. Bg5  h6  6. Bxf6  Qxf6  7. Qb3  a5   8. e3  a4!  9. Qc2   a3  10. b3  Bb4  11. Bd3  Nd7  12. O-O   O-O  13. Rac1  Qe7  14. Ne2   Ra5  15. Ng3 =

so stay tuned,
until the next update

A super-GM repertoire

From my research the English opening (1.c4!) seems a good
first move in top level chess. Although the fundamental differences
between various opening moves are small (*), and a good GM
obviously also tries to look at what the opponent usually plays,
or knows (repertoire). Yet fundamentally, it also matters to know
how theory  develops, for example:

1.c4 e5 (1...c6 leads to Slav2. Nc3 Nf6 3. g3! Bb4! (3...Bc5
4.Nf3! e4 5.Nd4 0-0 6.Bg2 Bxc3 7.dxc3 d6 8.0-0 Re8 9.Nc2
and White maintains a slight advantage.

Otherwise, after 1. c4  Nf6  2. d4 e6 (2...g6 leads to Gruenfeld
or Kings-Indian) 3. Nc3    (g3 also is possible) Bb4!  4. Qc2!  0-0
(5. e4!?   d5   6. e5   Ne4  7. Bd3  c5 8. Nf3  cxd4  9. Nxd4 Nd7
10. Bf4   Ndc5 11. 0-0  Nxd3=) 5.Nf3! d5 (c5 6.dxc5 Na6 7.g3!
Nxc5 8,Bg2 b6 [...Nce4 9. 0-0 Nxc3 10. bxc3  Be7 11. e4  d6
12. e5  dxe5 13. Nxe5 Qc7 14. Qe2  Bd6 15. Re1 Bd7 16.Bg5!N]
9.0-0 Bxc3  10.Qxc3 Bb7 11.Rd1! Qe7 12.Qa3! +/=) 6.a3 Bxc3
7.Qxc3 dxc4  
8.Qxc4 b6  9.Bg5  Ba6  10.Qa…

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…
