The pgn miss a "}" before 11.Rg1 here's the corrected pgn (+ variations instead
of comments for lines)
[Event "X3D Man-Machine match"]
[Site "New York City"]
[Date "2003.01.30"]
[Round "3"]
[White "Kasparov, Garry"]
[Black "Deep Junior 8"]
[Result "0-1"]
[Opening "QGD semi-Slav: Stoltz variation"]
[ECO "D45"]
1. d4
{I was operating again, and this time the guest of honour was legendary director
Milos Forman. He made this move for white, then sat down in the VIP section of
the playing room for the rest of the game. There are about 10 chairs for VIP's
about four meters from the board, but they are usually unoccupied because it's
much more interesting three floors down where Ashley and Seirawan are commenting
for the crowd. Klara Kasparova, however, is always there, keeping an eye on her
son}
1... d5 2. c4 c6 3. Nc3 Nf6 4. e3 e6 5. Nf3 Nbd7 6. Qc2 b6
{Here's where we differ from the previous game's 6...Bd6. Are we now going to
see a conventional line from the Semi-Slav ? Not if Kasparov can help it}
7. cxd5 exd5 8. Bd3 Be7
{We are out of book here}
9. Bd2
{What's this ? Is he going to castle queenside ?}
9... O-O 10. g4
{So that's the idea again. This time, we have to take}
10... Nxg4
11. Rg1
({Deep Junior expected} 11. Bxh7+ Kh8 12. h3 Ngf6){ While Kasparov was
considering
his next move I went out to the computer room and found Boris, much troubled,
analysing continuations after this line. I asked him: "Will he take on h7?". "He
has to", says Boris. "Can't he play say Rg1 ?". "No, then I play Ndf6" says
Boris.}
{Kasparov is not listening to Boris. Maybe in the spirit of the g4 move, white
doesn't want the pawn back, but much more. I believe he was out not only to win,
but to completely humiliate the program and get it over by move 15. This may yet
happen on another day, but today Junior found the right moves}
11... Ndf6 12. h3 Nh6 13. e4 dxe4
{This looks very dangerous now, but Deep Junior is not concerned. Evaluations
are level, and not falling. Every iteration that doesn't bring a massive
fail-low is a relief}
14. Bxh6
({We expected}14. Bxe4 Kh8 15. Bxh6 gxh6 16. Bxc6 Rb8 17. Qd2 Bxh3 18. Qxh6
Bg4{with advantage for white})
14... exd3 15. Rxg7+ Kh8 16. Qxd3 Rg8 17. Rxg8+ Nxg8 18. Bf4 f6
({Deep Junior didn't like }18... Qd7 19. Ne5 Qxh3 20. Qxh3 Bxh3 21. Nxc6 Bh4 22.
d5{and instead opted for this key defensive move, shutting out e5 and g5 for
white's minors. With the knight at g8 the king looks well protected now. At
around 0.5, this was the most negative score in the game, but in the next few
moves Deep Junior believes it equalizes})
19. O-O-O Bd6 20. Qe3 Bxf4 21. Qxf4 Bxh3
{This looks safe now. It is rare to see Junior defending a pawn up. It goes
against its temperament}
22. Rg1 Qb8
{Equalizing}
23. Qe3 Qd6 24. Nh4 Be6 25. Rh1 Rd8 26. Ng6+ Kg7 27. Nf4 Bf5 28. Nce2 Ne7 29.
Ng3 Kh8 30. Nxf5 Nxf5 31. Qe4 Qd7
32. Rh5
({We are showing draw scores for several moves now, and are now pondering} 32.
Qg2 {which for a while looks like flat draw, until we see} 32... Qxd4 {breaking
out. This should be interesting to analyze.}) ({Of course there's the more
direct}
32. Ng6+{. Black's next move, however, is no way to draw. I don't think Kasparov
was conceding a draw yet, either})
32... Nxd4
{Kasparov had 10 minutes to time control here, and was behing the curtain of his
private corner. When I played 32... Nxd4, he was audibly dismayed while still
behind his curtain without coming to the board! He then spent a full 5 minutes
reprimanding himself, and with 5 minutes left, got back to thinking about the
position}
33. Ng6+
{Deep Junior suggests 33.Rh1 and it's still playable for white. Does it work ? I
don't know, but I think Kasparov didn't consider it for even a second. It seems
that human players are incapable of accepting the price of a mistake and
rethinking the position objectively. The knight manouevre gets it over quickly}
Kg8 34. Ne7+ Kf8 35. Nd5 Qg7 36. Qxd4 Rxd5 {White resigns} 0-1
